Computer Network, Systems, and Database Administrators Are in Demand

2010-10-28T05:16:00.000+08:00

If you're looking for a fast-paced career that combines technology with creativity, check out the field of computer network, systems, and database administration. This dynamic career path reflects the increasing number of computer networks in business today.

In the workplace, computers and computer networks have become an integral part of everyday life. Nearly everyone who works in an office has a computer, and big companies may have thousands of workstations, each with a computer terminal. These computers don't just sit on desks like little islands; they need to be linked together into one seamless operating system. The ways that computers are linked together include local-area networks (LAN), wide-area networks (WAN), network segments, and Internet and intranet systems. Networks can be very complex, and creating a network of computers is a task that must be performed by highly qualified personnel.

Network and computer systems administrators design, install, and support an organization's computer network systems. Network and computer systems administrators work in a wide variety of organizations including professional offices, government organizations, small businesses, and large corporations. They analyze problems, maintain a company's network hardware and software, and monitor networks to ensure their functionality. Administrators may plan, coordinate, and implement network security measures, and they may gather data to identify customer needs and then use the information to identify, interpret, and evaluate system and network requirements.

Systems administrators ensure that the design of an organization's computer system allows all of the components, including the network, the computers, and software, to work properly together. They are often responsible for maintaining the network's efficiency, and they monitor and adjust the network's performance. They continually survey the current computer system to determine future network needs, troubleshoot problems reported by users and by automated network monitoring systems, and make recommendations for future system upgrades.

When the computers in the sales office crash, or when the finance people can't access their networked spreadsheets, or when the warehouse cannot access the intranet to track a shipment, the company can become paralyzed. A network systems administrator is the person who can, and must, resolve these network issues. It's an important position.

Education and training are key. A bachelor's degree is required for many network and computer systems administrator positions. In addition, many employers will demand that applicants have specialized computer network training of the type that may be offered by a career college. The best way to explore your career training opportunities is to log onto a reputable online college directory and compare computer training programs. Choose the ones that are right for you and request free information from the schools. This will allow you to make the best choice for your career education.

Here are some of the program areas that are key to this career field:

Connecting Lines - Computer Networking Explained

2010-10-27T11:39:00.000+08:00

In a nutshell, computer networking is basically a cluster of computers linked together in a way that it can transmit data and share resources. These sets of connections do not necessitate that the computers bear the same operating systems (OS); it does not even require that similar types of gadgets be used. A perfect example is a personal data assistant (PDA). One may connect a PDA to a laptop over a network. Even kitchen appliances like the internet enabled refrigerator uses networking to activate its surfing functions.

How Is Networking Done?

There are various methods to link computers and other gadgets to a network. And among the plethora of ways and means, the most common networking method is the use of cables. The market provides an assortment of cables from copper-wired to fiber optics each with its advantages and disadvantages.

Copper Wire: Unshielded Twisted Pair Cable (UTP)

The UTP is one of the frequently utilized cables for a local area network (LAN) connection, which is essentially linking a few computers within a small geographical area (thus the name, LAN). Going back to the UTP, this is composed of two unshielded and insulated copper wires coiled and twisted together to diminish electrical interference. This type of cable is often opted due to its flexibility, easy maintenance and low cost. The downside, it can (and will) possibly receive severe blows from electrical interference.

Fiber Optics

Data is exchanged by sending voltages along the wire. But for fiber optics, the data is transmitted through light pulses. While the UTP has copper, fiber optics has threadlike strands of glass, or silica. The process goes like this: the laser translates digital signals into pulses of light and conveys it down the series of glass strands. Fiber optics offer rapid data correspondence, though this speed comes with a price, a pocket burning price. With that said, this kind of connection is often seen being utilized by huge internet service providers (ISP) and data centers, not in office or home networks.

Network Topology: Bus Network

Simply put, network topology is the physical formation of the network. And the bus network is the most straightforward among the various network topologies. Let us begin with the bus. All the machines link up to a linear transmission channel, or the bus.

In operation, when a computer sends off data through the bus, all connected machines can see the data, otherwise known as packet. These packets possess pieces of information tagged as packet headers. And these headers, in turn, reflect the recipient or to which computer or machine the data is intended for. The bus inspects the header: if it is for that computer then the whole packet is recognized and received, but if it is not, it will be merely ignored.

The Downside: One at a Time

Unfortunately, the bus can only handle a single data at any given time. In here, two is a crowd. Imagine what could happen if three computers in the network simultaneously transmit data. Well, you will certainly have a few network problems if this collision happens. Speaking of collision, if and when two computers concurrently send data, the main computer (or the first one that notices the collision) will transmit a blocking sign onto the bus. This will trigger a standstill among the linked computers preventing any further data exchange.

Network Interface Cards (NIC)

NICs usually control the 'to and fro' or the transmission of packets across the wires bridging the computers in a single network. It also provides a venue of communication among the computers.

Hub

Hub is intended for small-scale computer networking. The problem with this is that it does not sort packets, meaning the data may be sent to the wrong recipient. Another is that the data will be open for everyone in the network. Security wise, this is not the way to go.

Router

To speed things up, this is a network device that diffuses data packets between two networks bearing different protocols. Yes, it is that blinking box that allows you to connect to the web.

There you go. This is simply scratching the surface of networking. You may opt to scour the internet for more information.

Computer Network Overview

2010-10-26T16:32:00.000+08:00

Computer networking or data communication is a most important part of the information technology. Today every business in the world needs a computer network for smooth operations, flexibly, instant communication and data access. Just imagine if there is no network communication in the university campuses, hospitals, multinational organizations and educational institutes then how difficult are to communicate with each other. In this article you will learn the basic overview of a computer network. The targeted audience of this article is the people who want to know about the network communication system, network standards and types.

A computer network is comprised of connectivity devices and components. To share data and resources between two or more computers is known as networking. There are different types of a computer network such as LAN, MAN, WAN and wireless network. The key devices involved that make the infrastructure of a computer network are Hub, Switch, Router, Modem, Access point, LAN card and network cables.

LAN stands for local area network and a network in a room, in a building or a network over small distance is known as a LAN. MAN stands for Metropolitan area network and it covers the networking between two offices within the city. WAN stands for wide area network and it cover the networking between two or more computers between two cities, two countries or two continents.

There are different topologies of a computer network. A topology defines the physical layout or a design of a network. These topologies are star topology, bus topology, mesh topology, star bus topology etc. In a star topology each computer in a network is directly connected with a centralized device known as hub or switch. If any computer gets problematic in star topology then it does not affect the other computers in a network.

There are different standards and devices in computer network. The most commonly used standard for a local area network is Ethernet. Key devices in a computer network are hub, switch, router, modem and access point etc. A router is used to connect two logically and physical different networks. All the communication on the internet is based on the router. Hub/Switch is used to connect the computers in local area network.

Hopefully, in this article you may have learnt that what a computer network is, how important it is in our lives, what are different network devices, standards, topologies and communication types.

The Critical Nature of Professional Computer Network Security

2010-10-25T06:41:00.000+08:00

In a world of ever-evolving and increasingly sophisticated Internet threats, computer network security has become an unmanageable necessity for many small businesses and homeowners.

It is more important now than it has ever been to put the needs of one's network into the hands of a highly skilled and experienced professional.

Even the small home network can benefit and save money by turning to a PC technician who has the proper software and tools for the job.

Proper computer network security takes the burden off our shoulders, and protects our small business and home networks from all threats.

Consider that these threats can expend far more energy attacking our systems than we can spend defending them.

When one considers the ever-expanding array of network threats, it is clear that we must allow specialists to manage our defense.

How else can we have confidence that all of our precious information is secure?

Consider the following evolving Internet-based threats:

Worms & Viruses

In addition to being the original form of malware and predating the Internet, viruses are still the most common and dangerous form of security threat.

Once they gain access to the network, they begin to spread until the network is disabled, compromised or both.

The fortunate aspect of worms and viruses are that they require user intervention in order to introduce themselves to the systems.

This means that with proper and professional security and protocols in place, a business can provide themselves with invulnerability to these types of attacks.

Phishing

Phishing is a criminally fraudulent process of attempting to acquire sensitive information, such as credit card information, usernames and passwords.

Phishing attacks generally target individuals, but this does not mean that our businesses are safe from this type of threat.

Our employees are more mobile, and more connected to our business networks than ever.

A phishing attack that compromises the employee can lead to a compromise of the business' entire computer network security.

This is why it is critical that we use professional measures to protect our employees and, in turn, protect ourselves.

Packet Sniffers

Packet sniffers capture network data streams, thus allowing them to seize a business' sensitive information.

Packet sniffers are very difficult to detect, and they can gain access to the network through legitimate connection means.

In order to secure a network from this type of threat, every point within the network must have proper security protocols, and be able to transmit and receive encrypted communication.

A business must employ a network security specialist in order to implement a system such as this.

Securing All Components of Network Access Control

The common small business owner or homeowner does not appreciate the complexity of fully securing a network.

There are four primary phases:

? Authentication

? Enforcement

? Endpoint Security

? Management

Defend your business from all computer network security threats by hiring a network security consultant that will properly secure and define protocols for each of these phases. Network security is like a house of cards. If just one of these broad aspects fails, the entire structure falls apart.

Security is very important when it comes to saving your business computer network.

This is why it is very important to find a computer technology specialist to manage your company's computer network.

Setting Up a Small Business Computer Network

2010-10-24T12:23:00.000+08:00

How to Set Up a Computer Network for Your Small Business

Small business computer networking has become common practice in the current business world that relies so heavily on evolving technology. While it may seem like a daunting task, setting up network technology has become a do-it-yourself project that doesn't require hiring a techie or specialist. With the following information you can acquire the tools to set up your own business computer network.

The advantages of networking computers center on the concept of efficiency. A network allows you to make optimal use of your computers and tech devices, perhaps in ways you weren't even aware of. Networks promote the sharing of resources, whether those resources are files and software or even physical devices such as printers. The Internet connection itself is also shared by the range of computers employed. Setting up a network is one of the best small business ideas for improving productivity by creating a sense of community among both technology and employees.

The debate of wired versus wireless comes down to personal preference. Wireless equipment has become more popular due to lower prices and ease of use. The wireless approach allows a greater degree of freedom in the fact that you don't have to rely on cables or having your technical equipment in a certain area. That's not to say Ethernet (wired) networking is obsolete. Wired connections tend to more reliable and speedier than wireless, meanwhile remaining untouched by variables that tend to impact wireless connections.

The starting point of small business computer networking comes in your choice of operating system. Again, this has a great deal to do with personal preference. Windows 7/Vista/XP and Apple OS X are the standards and should serve you well, especially if you're already familiar with them. Each has built-in networking abilities that are easy to manage from a laptop to desktop computer. Outside of actual computers, you'll need some equipment. This includes a router (possibly two or more if setting up over a large area) and a few Ethernet cables. Wireless networks will require a cable to link your router to a central computer that will represent the server. This will link the router to your Internet connection, allowing external computers with wireless capabilities to connect to your LAN (local area network).

How do you keep your computer wireless network safe? Implementing a password may be a basic first step which will help weed out those attempting to illegally access your server. WEP and encryption software for businesses also serve as a further step for keeping outsiders from getting into your network. Much of this can be set up within the operating system. Additionally, you can use your browser security settings to prevent attacks on your server. Small business computer networking has become commonplace and should be embraced by those looking to make their business more efficient in a time where business and technology go hand in hand.

Computer Network Management

2010-10-23T20:01:00.000+08:00

Today it is almost inconceivable for a business not to have computers, whether it is a construction company or a high technology firm. When a business has more than one computer, they are almost always connected together in a local area network. These networks may be more or less advanced and therefore more or less costly.

Companies invest so much (in terms of both money and time) in a local area networks because there are many advantages that a local area network brings to a business and how it is administered.

Some businesses use a local area network in such a way they are highly dependent on it always working. If the company's network fails, then you may see all the employees chatting away in the corridors because they can't do their work. This means big losses for the company and causes stresses on the employees. All companies must consider their local area networks a vital asset and downtime must be avoided. This imposes huge demands on the network staff to keep such networks running almost 100% of the time.

The advantages of Computer Network Management

One of the main advantages of installing and maintaining LANs is the opportunity they create for better communication and cooperation between employees and customers.

Security considerations: Local Area Network security can be both a help and hindrance. Comprehensive security is beneficial because it provides a central and safe strategy for data access and disaster recovery. All information is protected by the design and implementation of the network security solution. On the other hand, interconnecting computers in local area networks creates a security risk, since doing so makes it technically possible for intruders to access many machines on the network at once.

Cost considerations: Installing a local area network is a relatively expensive project. Servers, cabling, switches, routers and software can all be expensive and should never be purchased without expert advice. Keeping the network operating and secure also requires a lot of resources and can be costly.

Surprisingly, a local area network can bring a number of cost savings. Sharing resources avoids the need to purchase equipment for each individual. Even more important is the security that a local area network can provide. Data loss could cost a business a great deal of money and in some cases, cause the business to shutdown altogether. Computer Network Management should require a consistent routine for data backups with regular checkups of data quality - a practice that will save a company huge sums in the event of a mishap.

Computer Network Management: preliminary analysis phases

The first phase of computer network management is to determine the source of the problem (a preliminary study that looks into several options of differing scope may be useful here) and defining it in a specification of requirements. Examples of what should be evaluated are different network operating systems, mail systems, and other applications. The choice of hardware components should also be evaluated. This phase is generally aimed at establishing what the system should do, not how it should do it.

Computer Network Management: design phase

The purpose of design phase is to determine how the requirements of the specification are to be met. The current approach to large, complex projects is to break them down into smaller, more manageable subprojects.

Computer Network Management: implementation phase

This phase involves the physical installation of the local area network. Cables are run, software is installed, and computers and other hardware are put in place.

Computer Network Management: integration and system testing phase

In this phase, commissioning of the network begins, and routines are adapted to users and the operating personnel. The system must be tested, both to ensure that the network meets the requirements set out in the specification and that it is stable enough to perform the central function it has in the organization.

Computer Network Management: operation and maintenance

Local area networks have complex operating routines. This is because there may be serious consequences when faults occur or unauthorized persons gain access to the system. Many companies have employees devoted solely to take care of running and maintaining computer networks. These system administrators may deal with network issues such as performance, reliability and security of both hardware and software.

Computer Network Management: tools

Although an organization may have computer administrators on site, they must also monitor the network more than eight hours a day. In fact, some of the worst trouble that arises with networks can happen during the night hours when nobody is using the network. With the right computer network management tools, your organization can receive the security of knowing that problems will be foreseen, prevented, and taken care of - and that your network administrator can be notified at a moment's notice, should anything go exceptionally wrong.

An Overview Of Computer Networks

2010-10-22T20:37:00.000+08:00

My second degree, or should I say my second go through inside the education system was in networking. I'm a certified Novell and Microsoft engineer, not that I'm all that excited about the fact. Networking is actually pretty mindless work once you learn it. It's pretty much do it by the numbers based on what the customer wants. After you hook everything up the software installation is pretty straight forward. My 16 year old daughter could do it or as GEICO would say, a caveman could do it.

In this article I'm just going to cover the basics of what a network is and the types of networks. I'll go into more detail in later articles.

A network is simply a means for computers to speak to each other, or communicate with each other. With a network, computers can receive emails from each other, send files to each other, instant message each other and a variety of other things. This is something that we take for granted today but there was a time when networks were not so sophisticated and not all that efficient either.

There are basically two types of networks.

The simplest network is a LAN or Local Area Network. This is where all the computers in the network are located in one place such as an office building. Within this type of network you have 2 ways to connect.

The simplest way is peer to peer. This is where 2 or more computers are hooked up directly to each other. In other words if you have 5 computers you would have computer 1 hooked into computer 2 which would be hooked into computer 3 and so on. In this type of connection each computer is dependent on the other. So if computer 3 would go down then computers 1 and 2 would not be able to communicate or exchange information with computers 4 and 5 and visa versa. That is the main problem with a peer to peer network. Also in peer to peer networks the write process between computers leads to data corruption problems. This is not something they teach you in school but something you learn from experience.

The more common type of LAN connection is client server. This is where all the computers in the network are connected to each other via a central computer. This kind of connection does require more work in set up but is more efficient, carries data better and if one computer goes down the others aren't affected. However, should the server go down then all the computers on the network would be affected as far as their ability to get information from the other computers and the server itself. They, however, would still be able to do work locally on their own such as with a word processing program, unless the word processing program was located on the server. Then it would not be available. Usually, however, most applications are installed on each computer. What is most commonly lost when a server goes down is the ability to retrieve data that is common to everyone in the network, say an in house database of all employees.

The second type of network is a WAN or wide area network. This is where several LAN networks or even single computers are connected to a much larger network. A perfect example of a WAN is the Internet. This is where users from all over the world can interact with each other through email, chat rooms and instant messaging. WANs are enormous to say the least and are very intricate in their design, requiring hubs from all over the world to stay connected. One hub goes down and it can affect connections for millions of people though there are protocols instituted to reroute connections if a hub does go down.

The above is a very simplified overview of computer networks. In future articles I'll go into detail on the hardware and software required to set up these networks and some of the finer points. Stay tuned.

An Overview of the Computer Network Devices & Components

2010-10-22T07:57:00.000+08:00

A Computer network is comprised of different devices to share, transmit, and boost the signal, voice and data. Network devices or components are the physical parts connected to a network. There is a large number of the network devices and are increasing daily. The basic network devices are: Individual Computers, Server, Hub, Switch, Bridges, Routers, Modems, Printers, DSL Modems & Routers, Gateways, Network Interface Cards, Cabling & Wireless access point. The following is a overview of each of these network devices.

INDIVIDUAL COMPUTERS: The personal computer is usually a desktop computer, a work station or a laptop. The personal computers are most widely used in any organization or for personal use. The individual computers are the most common types of the microcomputers.

SERVER: A server is a computer on a network, which process request and is used to share the data and resources among the other computers in a network. A server stores all the necessary information and provides the different services like, workstation computer's logon access, internet sharing, print sharing, disk space sharing etc. There are different types of servers e.g File and print server, database server, proxy server, Fax server, backup server etc. A database server stores all the data and software, which may related to the certain database and it allows other network devices to access and process the database queries. A file server is used to store the data of any user on the network and a print server manages one or more printers in a network. Similarly a network server is a server that manages the network traffic.

NETWORK INTERFACE CARD: Network interface cards are attached with the computer or other network devices and are used to provide the connectivity between the two computers. Each network card is specifically designed for the different types of the network like Ethernet, FDDI, Token Ring and Wireless Networks. The Network card operates on the first and second layers of the OSI models i.e Physical layer and datalink layer specifications. NIC basically defines the physical connection methods and the control signals that provides the timings of the data transfer over the network.

HUBS: Hub is a simplest network device. The function of the hub is broadcasting i.e data is forwarded towards the all ports of a hub, regardless of whether the data was intended for the particular systems in the network or not. Computers in a network are connected to a hub with a twisted pair (CAT5) cables. There are two types of the hubs. 1. Active Hubs. 2. Passive Hubs.

SWITCHING HUB: The Switching hub (also called "switch" is the most advance shape of the basic hub. In a basic hub all the computers are connected with the hub and the speed of the network is defined by the slowest computer network card connected. For example if you have 10/100 Mbps cards in a network and only one card of 10Mbps speed then the system cannot run faster than the 10 Mbps. Now if you have a switching hub in a network, it will allow all the faster connections in the network to remain at the higher speed and still interact with the 10Mbps system.

SWITCHES: Switch is a intelligence device than hub. Switch is a layer 2 device. Swith provides the same function as a hub or a bridge but it has the advance functionality of connecting the two computers together temporarily. Switch contains the switch matrix or switch fabric that can connect and disconnect ports. Unlike hubs, switch only transmit or forwards the data to the destined computer and it does not broadcasts the data to all its ports.

MODEMS: Modems are the devices, which are used to translate the digital data into the analog format and vice versa. It performs the two main functions. Modulation and demodulation. A modulated data can travel across the conventional telephone lines. The modem modulates the signals at the sending end and demodulates at the receiving end. Modems are required for different types of the access methods such ISDN, DSL and 56K data modem. Modem can be the internal devices that plug into the expansion slots in a system or can be external devices that plug into the serial or USB ports. In Laptops, PCMCIA cards are used for this purpose and many new laptops having the built in integrated modems. The specialized devices are designed for use in the systems such as handheld computers. In ISPs where the large scaled modems are required, rack-mounted modems are used.

ROUTERS: Routers route the data between two logically and physically different networks. A Router has the capability to determine the destination address for the data and hence provides the best way for the data to continue its journey. Router gets this capability through its software called routing software. Unlike Switches and Bridges, which use hardware configured MAC address to determine the destination of the data, router uses logical network address such as IP address to make the decision in determining the destination of the data.

GATEWAY: A gateway performs the function of translating the data from one format to another format without changing the data itself. A gateway can be a device, system, software. A computer with two NIC cards can function as a gateway. Router acts as a gateway e.g a router that routes the data from a IPX network to a IP network is technically a gateway. The same can be said of translational switch converts from a Ethernet network to a token ring network.

CABLES: There are two most common types of the cables. 1. 10baseT and 10base2. 10baseT is a four paired cable. 10baseT has further two types 1. UTP (unshielded twisted pair) and 2. STP (shielded twisted pair. STP is most secure cable covered with the silver coated twisted paper to protect the cable. On the other end Thin 10base2 looks like the copper coaxial cabling that often used to connect TV sets and VCR. 10baseT/Cat5 cables are most commonly used cables to connect the computers. It has the connector, (like a telephone connector) called RJ45 connector.

Twisted pair cables are ideal for the small, medium or large networks.

My recommendation for using cables for networking is to use 10baset/Cat5 cables

Computer Networking - Higher Education Programs Online

2010-10-21T09:29:00.000+08:00

Computer networking has become an integral part of everyday life. Networks are used by multitudes of people from the businessmen that share information with each other to the teenager uploading photos to a social networking site. The role of online education in computer networking is to teach students to keep networks working and usable. Education is obtainable from numerous online universities that offer several concentrations.

The connection between computers that share information defines the industry of computer networking. This is a complex system that needs the constant work of specialists. Online training encompasses many aspects of the field, which includes network design, troubleshooting, maintenance, and information protection. Based on career trends, having an education is quickly becoming a standard due to continually advancing technology. Students learn how to be specialists that provide daily support, train individuals to use a system, and develop a network for a company. These are only a few areas that are covered through courses in a program.

Computer Networking Fundamentals

2010-10-20T09:56:00.000+08:00

In the past, when two persons were willing to share data between each other, they were relying on movable disks such as floppy disks and CD-ROM. These ways of transmitting data between remote computers are often difficult especially if the files will be transmitted very often.

Because of the above difficulties in transmitting data across movable disks, the idea of networking two or more computer has been arisen. Instead of transmitting the files across movable disks, the computers are connected to each other by cables through ports on the computer. When someone needs to transmit the data to another computer, he simply can share the files he needs to transmit across the network. This way no movable disk is needed and the matter is easier.

When talking about computer networking, one must differentiate between the many types that exist for the network. The computer network can be classified according to the geographical area they occupy or according to the manner they will behave when sharing and accessing data between the computers in the network.

Let us first see how they are classified according to the geographical area. The meaning of this classification is how much the network will occupy or simply what the size of the network is. There are three types for any networks according to this classification. They are the LAN, WAN, and MAN. The LAN (Local Area Network) has the smallest size with respect to the other types. The LAN can occupy a room, a floor, a building such as company, or at most a group of adjacent buildings. The MAN (Metropolitan Area Network) can occupy a whole city or even a while state. On the other hand, the WAN can occupy a whole country, group of countries, or even the whole world.

The second classification is according to the data distribution across the network and how the computers that are connected to each other are treated. There two types of networks according to this classification. The first one is peer to peer network. The meaning of this classification is that all computers in the network are treated as equal. Thus the size of the data on one computer can be equal to the size on another computer. Also the processing and storage power of the all devices are equal. Thus there is no computer on the network that is higher in value than the other computer. Hence the name peer to peer network.

The second type of networks according to the above classification is the client-server network. In this type, the matter is different in that not all computers are equal in value. At the least, there is one computer (that is called the server) that has much processing power and storage power. Therefore the data is stored on that computer to be shared across the network. Every computer that needs some data that is shared across the network can take it from the server only. This is because all computers other than the server have less sizes of memory and also processor power.

Types of Computer Networks

2010-10-19T17:27:00.000+08:00

There are different types of Computer Networking that you may need for your home or office. To begin with you have the option of a wired or wireless computer network. These types of networks differ. A wired computer network will have copper or fiber optic cabling running between computers while a wireless network uses radio waves and/or microwaves to maintain communication channels.

A client/server network works by using client devices, typically PCs with network software applications installed that request and receive information over the network. The server device will usually store files and databases and includes more complex applications like Web sites. These devices often feature high-powered central processors, more memory and larger disk drives than the client devices. Two examples of client-server systems include Web browsers and servers.

In addition to these types of networks there are also types of area networks. These are categorized by their scope or scale. Some area network types include:

o LAN

o WAN

o WLAN - Wireless Local Area Network - a LAN based on WiFi wireless network technology

o MAN - Metropolitan Area Network - a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned an operated by a single entity such as a government body or large corporation.

o CAN - Campus Area Network - a network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus.

o Storage Area Network - connects servers to data storage devices through a technology like Fibre Channel.

o System Area Network - links high-performance computers with high-speed connections in a cluster configuration.

LAN and WAN were the original categories of area networks but through the evolution of technology we have been forced to keep adding more and more types due to the ever-changing field.

A LAN network will connect devices over a relatively short distance. This may include a building, school, or home that will contain a single LAN. Sometimes one building will contain a few small LANs and on the other hand a LAN may span a group of nearby buildings. A WAN spans a large distance. The Internet is the largest WAN as it covers the Earth. A network device called a router will connect LANs to a WAN. These are typically not owned by any one organization like LANs but are under a distributed ownership and management system.

Computer Networking Services

2010-10-17T04:39:00.000+08:00

A computer network is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. This interconnected system will share services and interact through a communications link. If data is being sent over the system then the individual computers must follow a set of common communication rules in order for the data to arrive at is correct destination. This is also vital for the systems to properly understand each other otherwise data will not be received. These rules are known as protocols.

So, in order for a computer network to be set up properly four things must be present: two or more systems, something to share (such as data), a communications link or physical pathway, and a set of rules for communication or protocols.

Wireless computer networking uses radio waves and/or microwaves to maintain open communication channels between computers. This version of computer networking is a more modern approach and is an alternative to wired networking. The advantages of wireless computer networking are that this involves mobility and the elimination of a copper or fiber optic cabling running between computers. However, a wireless computer network has the potential to have radio interference due to weather, other wireless devices or obstructions.

If you are unsure what type of computer network you would like you can have a trained professional come to your home, business, or other location and have them recommend what you need depending on what you are using your network for. You should always hire a trained computer specialist when setting up a computer network as there may be complications and it can be very difficult to learn how to set up a computer network by yourself.

Easy to Understand Definition of a Computer Network

2010-10-16T16:07:00.000+08:00

By definition a network is a group or system that interconnects components together. A network of retail stores, for example, implies some sort of relationship between the stores. A railroad network suggests that the tracks interconnect at different points. And a computer network interconnects computers.

By far the most famous computer network in the world is the Internet. The Internet is, in fact, a collection of smaller networks that are interconnected together - a network of networks if you can imagine that.

But computer networks don't necessarily have to be large or complex. By definition, the smallest possible computer network would include just two interconnected computers. The interconnection can be achieved using a cable or by wireless technology. Whatever the medium, as long as the computers can communicate together they are part of a network.

Surprisingly, the Information Technology industry doesn't define networks by size, rather, by location. Computers that are interconnected in a small geographical location such as a home or an office are said to be in a LAN (Local Area Network). A LAN can have two computers or two thousand computers.

Conversely, computers that are connected across a wide geographical area such as between cities or countries are said to be in a WAN (Wide Area Network). Strictly speaking a WAN actually interconnects LANs. Five computers in a New York office are in a LAN, however, the New York office also connects to an Office in Chicago who hosts ten other computers. All together, that network is said to be a WAN spanning New York to Chicago. But individually each office is a LAN in its own right. One LAN in New York and one LAN in Chicago. This is why we say that strictly speaking a WAN interconnects LANs.

A description of how the network is wired together can be provided using a physical network topology. Network topologies are used to describe the different ways to connect computers together. A bus topology, for example, describes computers connected across a common wire in a linear fashion. A star topology describes computers connected to a common central device such as a switch. Other types of common topologies include ring topology as well as mesh and partial mesh topology.

But possibly the most important working components of a computer network are the protocols. A protocol is a set of rules. In order to communicate correctly, computers must talk the same protocol so that they understand what is being received and know how to send information in return. The IT industry has successfully established TCP/IP as the dominant network protocol across the world. The standardization of TCP/IP in computers has allowed the internet to thrive because is provides a common language that computers can use to communicate with each other.

Networking careers are sought after and rewarding. Visit us to discover IT books and world class Network Training Solutions for all levels.

What Hardware Is Needed for a Computer Network?

2010-10-14T21:49:00.000+08:00

The hardware that you will need for setting up your computer network will be the computers, the interface cards, peripherals and whatever is needed to allow data-processing as well as for communicating between the network computers.

File servers are needed. They are rather quick computers with a lot of RAM and a fast network card as well as storage. The operating system for the network is on this computer and if data files and/or software applications need to be shared they are here as well.

File servers must have a microprocessor that is at least 800 megahertz, preferably more. The hard drive will need to have storage of 120 gigabytes or more. A RAID is needed to keep data if there is a problem with the disk. A tape unit for backup which can be a Zip, JAZ, DAT or CD-RW drive is needed.

Another requirement will be several expansion slots and a network interface card (preferably a fast one). Also needed for networking at the very least 512MB of RAM. A network interface card (NIC) is going to provide the connection needed between the computers and the network. All the computers that are connected to the network are workstations.

Workstations will be the computers that have been connected to the network. The standard workstation is the computer which has been specifically arranged with the cables, the networking software and a network interface card. The computer does not require a floppy disk drive since files can be kept on the file server. Practically any computer can be a network workstation.

What else is needed for the computer network? A router is needed for translating the information to all the networks. This can be compared to a bridge. The router chooses the best way to send a message using the destination address and the origination of the address. It sends the message by routing it to keep it from colliding with other messages. The routers know the computers' addresses and the other routers on the network as well as the bridges. They even know which sections are busier than others and redirect the data until the sections are not so busy.

Repeaters are a necessity due to signals losing their strength when they are passed using a cable. The signal may need boosted and this is where a repeater comes in handy. It can transmit the signal by amplifying it and rebroadcast. The repeater can be a single unit. It can also be combined with a concentrator. This is necessary when the length of the network cable is longer than the standard for the cable used.

Providing a connection point that is central to the cables from peripherals, servers and workstations is a device called a concentrator. In computer networks often a twisted wire goes from each and every workstation to a central switch. The switches amplify the signal as it goes from one place to another. Rather than broadcasting network packets, switches or hubs as they are often called, memorise the computer's address and send the data to the right location.

So, there you have the many elements that are needed to connect a computer network. This hardware, when attached correctly will allow you to set up your network and start moving data.

Brandon Douglas Bradshaw has studied IT and computer systems for many years and it have become his passion. In his studies she has discovered some very important foundational facts. Computer networks can be defined as an engineering discipline regarding the interaction between devices of computer and computer systems. Routing protocols, networking, routers and entire networking system over the internet services have their details defined in documents termed as RFCs (request for comments). Computer networking is also considered as a discipline of computer science, telecommunications, computer engineering and information technology. It deals with practical and theoretical applications of these engineering and scientific disciplines. There are three kinds of computer networks: 1. Internet 2. Intranet and 3. Extranet.

Generally a computer network is sets of various devices and computers that are associated to each other having capability to send or receive data. Here is the list of different kinds of computer networks that Brandon Douglas Bradshaw is experienced with:

* LAN (Local Area Network): this is a small network deals with local and small regional area. Like a computer network covering a building.

* MAN (Metropolitan Area Network): This is medium size network deals with a city or state.

*WAN (Wide Area Network): This is a bigger network deals with large geographic area.

* WLAN & WWAN (Wireless LANs and MANs): These networks are the equivalent of the WAN and LAN in a wireless form.

There are all kinds of computer networks that are connected to each other to let the communication be done among various Medias like copper wire cable, optical fiber, coaxial cable, micro wave system, power lines and different wireless technologies. The devices regarding computer set-ups can be operated within a few meters or unlimited distances, depending on its range.

There are many organizations such as insurance companies, railways, hospitals, banks etc that needs real time processing of huge number of transactions via many computer systems in order to interact and communicate with each other via same network. Thus the installation procedure of an entire computer group is very important as well as sensitive also.

Overall, Brandon Douglas Bradshaw had discovered that in an ideal computer network the system, software and hardware must work together seamlessly. There are many software solutions and hardware solutions companies ready to serve you if you have any trouble with your own network system. A network security system with supported services should be applied to assist the whole computer network and keep the network safe from virus and spamming.

Uses of Computer Networks

2010-10-13T12:31:00.000+08:00

Computer Networks are everywhere. From the distributed systems to the middle ware and to the world wide web, computer networking has proved to be improving in techniques to reach remote areas and applications to serve the purpose.

Business Applications: Resource sharing is one of the most popular use of computer networks in the business applications. For Instance, a printer is shared in a network and hence saves a lot of investment in hardware. The computers connected in a network can make use of the printer in the network instead of having separate printers for every computer. Scanners, Cd burners, Fax machines are few other resources which can be shared in a network. Email facility with the help of Outlook application has enabled communication among the members of the company in sending reports and analyzing data. There would be a server handling the requests of all the computers connected in the network. Clients pass the request and the server works on the request by giving the reply.
Home Networking: Computers are now a days used just for person to person communication with the help of Internet. Internet can be used to have remote access to the information, person - person communication as discussed earlier electronic commerce, Interactive entertainments like games. Interactive entertainments such as XBOX gaming online and online tutorials which used flash for interactive environment. Now a days, people are buying a computer just for the sake of checking their email which enables person to person contact. With the help of VPN ( Virtual Private Network) one can work and access of office data right from home. In peer -peer systems there is no client system. Every computer in a network is connected to every other computer through wire.
Mobile Users: With the advent of technology in improving protocols for better communication, WAP (Wireless Access Protocol is now being increasingly used to communicate in a network. There are two forms of wireless: Fixed Wireless and Mobile Wireless. Desktop computers in an office are neither fixed nor mobile wireless. A notebook computer used in a Hotel room with the help of Ethernet cable is an example of mobile wireless and not of fixed wireless. Networks in old unwired building is an example of typical fixed wireless and not of mobile wireless. Portable office or PDA for store inventory is a perfect example for fixed as well as mobile wireless technology being used. M-commerce is using mobile device for paying cash using credit cards and act as an electronic wallet.

The Broad Categories of Computer Networking

2010-10-11T08:08:00.000+08:00

For some people, the computer itself could be a scary topic, considering the fact around how complicated the machine is. Talking about computer networking could give a heart attack to such people. However, it is not as scary as it may sound.

Computer networking could be understood by separating the two words in the term. A "computer" as we know is a complex machine that helps us to process information. "Networking" refers to linking or connecting. Hence computer networking would simply mean getting two or more computers connected. When we say the word "connected" in this reference, we mean that one computer could be accessed through the other.

Broadly speaking there are two ways of connecting two or more computers. The first one is called the wired network and the other one is called the wireless network. Both of these are huge subjects to study and understand. However, in layman's language it could be said that when two or more computers are connected through wires it's called the wired network. And when they are connected without the wires through wireless router, it is known as wireless network. As the wired networks are limited to the area wherein the wire web is installed, similarly the wireless has range limitations. The number of machines that are on a network would ensure the speed of the network. More machines in a network would mean a slow network.

The various computer network systems could be - Personal Area Network; Local Area Network; Campus Area Network; Metropolitan Area Network; Wide Area Network; Global Network and most importantly internet, intranet or the extranet. The names are given to the network depending upon the arena they have. Like for example the campus area would mean the machines that are in a given physically limited campus are connected through the computer networking. This could be wired or wireless networking.

Internet could be understood as a global network system.

E-Commerce Supporting Technologies - Computer, Computer Networking, Internet, Internet Connectivity

2010-10-10T13:11:00.000+08:00

E-Commerce as the word suggests means doing business on the internet or on-line. The scope of business may involve:

o selling hard goods on-line such as a phone, computer or shoes

o Electronic goods such as e-books, mp3 music, software, graphics or pictures

o selling ideas or services

To sell the goods the merchant has to have a website or a virtual store on the internet for him to sell the goods on line. A prospective customer finds that site, buys goods on it, pays owner using a credit card or via other mode. Merchant receives payment and deliver the goods and supports the customer. Practically, that's e-commerce in its simplest sense.

In between those e-commerce transaction a lot technology are involve to complete the sale. For instance, the merchant has to design and build a website developed using a complex programming language called HTML. Merchant has to register a domain name to identity his business on the internet. All information and products from his on-line store or business are encoded and stored on the merchant's computer server or hosted by a third-party web hosting company. In order for the customer to find the merchant's site, he needs a computer that is in turn connected to a system popularly known as the internet, for him to be able to visit the merchant's site.

The Personal Computer in relation to E-Commerce

A PC or Personal Computer is a computing device or tool built around a microprocessor. It has lots of different parts -- memory, a hard disk, a modem, etc...That work together. It is also called general purpose equipment. General purpose means that you can do many different things with a computer. You can use it to type documents, send e-mail, browse the Web and play games.

On each own, the computer can be used to expedite the processing and storing of information such as word processing. It can also be made to transmit and receive information from other computers. These computers can talk and exchange information from each other thru a common computer language or protocol. The PC is the most valuable and core-technology needed to drive E-Commerce and Internet Business.

Computer Network in relation to E-Commerce

Two or several computers can be physically linked and made to communicate with other computers with in a local network (LAN). The term use to describe this interconnection is called networking. Networking of computers can be made using either a wired (cable) or wireless (radio) type of connection. Usually, networking or the linking of computers is subject to the range or distance limitation because the signal and quality of communication will degrade as distance increases. Computer Networking is applied for most on-line internet business for an efficient and productive E-Commerce business.

The Internet in relation to E-Commerce

The internet is a system that connects computer networks. The system of internet enables the interconnection of computers all over the world. It allows your computer to get stored information from other computers far away.

The protocol (TCP/IP) or language when computer communicate in a network is similar to the one used on the internet. That is why computers around the world understand each other despite different maker and place of manufacture.

Lots of computers all over the world are stored with lots and lots of information. The internet system hooked them together. If you have access to the Internet, you can read, hear and view all this information from your own computer. The Internet is all the reason behind the existence of E-Commerce and without internet connectivity virtual on-line business will totally cease to exist.

Telecommunication in relation to E-Commerce

A different type of technology is needed to transmit information from one computer to another over long distances. Telecommunication companies come into the picture to service the requirement of connecting one computer network to another computer network using different kinds of transmission technology.

Telecommunication is a broad term as it also covers not only data communication such as the internet but includes voice telephony as well.

Telecommunication companies are driving internet businesses to achieve internet connectivity. Without them one could never put their business on-line as only telecom companies are able to link networks over very vast geographical distances.

Connectivity in relation to E-Commerce

Connectivity is a broader term than networking. Networking refers to the physical (wired) or virtual (wireless) connection between computers. Connectivity refers to the state of being connected. For instance, a computer can be sync to a phone, music player and other devices. Internet access or the state of being connected to the internet information super-highway is a classic example of connectivity.

Internet Connectivity is important both in urban and rural-remote regions of the world.

Some regions are suffering from lack of telecommunication infrastructure thus internet access service is very limited. In order to achieve internet connectivity, remote villages either use satellite link, wireless radio systems and long-range phone extenders. Some communities have established telecentres which serve as a communication hub and outside link to the rest of the world. All forms of connectivity including internet connectivity are helping push the envelope of internet business as a whole.

So you've read about e-commerce overview and its supporting technologies. Try to imagine and picture out how e-commerce is being practice and how important are those technologies to making it possible.

Your business is growing. You've added 2 new staff members in the past year, and all 5 employees are complaining about the increasing difficulty of sharing files. Your billing database is on a computer which can only be accessed by your administrative assistant, and you are concerned about not having a centralized backup of the files being saved on each employee's computer. If this all sounds familiar, it may be time to implement a computer network.

In this discussion, we'll look at two main computer network solutions for small and medium businesses. We'll explore the pros and cons of each type so that you can decide which network might be the best solution for your business.

Network Basics

Networks begin when two or more computers are connected so that information can be shared. In order to connect to any kind of network, a computer requires a network card and CAT5 or CAT6 cables. (If the computer has a "wireless" network card, radio signals can be used in place of the cables.) A network also requires a piece of equipment called a switch, which acts as a central routing "hub" for the information being shared. A switch is kind of like a mail room in a large company. It makes sure the addressed messages get to the right recipient.

Peer to Peer Networks

The most basic type of network is a called a peer to peer network. This type of network consists of several computers which are connected to each other. The "network" consists of shared folders located on computers within the network. These folders are set to a "shared" status, so that other people connected to the network can access them. Each shared folder is accessed by the users of the network, who set up a certain drive letter (say H:) as a "pointer" to the shared folders on other computers. In addition, any printers connected to any computer can be shared to other network users.

Benefits of a Peer to Peer Network:

A peer to peer network is inexpensive to set up. It uses the built in networking capabilities of Windows XP Professional (or Vista Business), so no special software is needed. It allows for file and printer sharing, and can be an adequate choice for a very small office.
Limits of a Peer to Peer Network

Peer to peer networks are dependent upon the computer knowledge of each employee, as certain rules must be followed in order to minimize network interruptions. If a user shuts down his machine in the middle of the day, other users on the network lose access to the files in that machine's shared folder. In the picture provided above, the laptop might only connect to the network when an employee is not traveling. Any files stored on that laptop are not available (and may not be backed up) when that employee is out of the office. Network and data security are weak. Files are not centralized, so getting a back up of all critical files is more difficult. Ongoing tasks like anti-virus scanning and Windows updates are localized on each machine. Updating virus definitions and patches has to be done manually at each machine, which is time consuming.
Client Server Networks

A more common type of network is called a client server network. This type of network uses a central server and specialized network software. The server is dedicated and is only used to store files and run server tasks. The computers which connect to the server are called clients and these are the machines the company staff would use. The server acts as the "hub" of the network, and does most of the "behind the scenes" maintenance and storage. Common server network operating systems include Windows Small Business Server 2003 or 2008, Windows Server or Linux.

Benefits of a Client Server Network

The server stores all of the shared files for each user. The server runs the file backups which can be scheduled in the middle of the night, minimizing network interruptions. The server manages user security, and insures that all users who access the network are authorized to do so. The server manages printer sharing and acts as a central repository for the printer drivers and settings. The server manages other common tasks such as internet access, email routing, Windows updating and anti-virus definition management. The server can also share software applications out to multiple users. The server can also provide for an "Intranet", an internal website which holds shared company information such as news announcements, HR policies, training documents, and more. In short, a client server network provides for easier network administration, and provides a much more robust environment in which provide secure and manageable access to company data.

Limitations of a Client Server Computer Network

A server based computer network is more expensive to implement. Server computers are powerful machines with built-in redundancy and other hardware to provide data safety. Hence, they cost much more than a simple desktop computer. The server network software is also much more powerful, complicated, and must be installed correctly to run all of the required tasks, and so the cost is higher for both the software and installation charges. The server is a critical point of failure. If it goes down, the entire network comes to a halt. This drawback can be minimized with the installation of redundant drives in the server (so that if one fails, the others will still be working), and even a second server that can take over if the primary server fails completely. Cost then becomes the only issue.
Which Computer Network is Best For Your Business?

Peer to peer computer networks are reliant upon the computer users, so employee behavior is a major factor. Peer to peer networking could work for your business if you have the following:

Computer savvy employees whom you trust. Low employee turnover. Five or less employees. Newer desktop or laptop machines with lots of memory and hard drive space. A large capacity portable data storage unit for backing up files and taking them off site. Time and motivation to keep the computer patches and maintenance up to date.
A client server computer network is more secure, easier to manage, and would be a better solution for your business if the following is true:

You want to secure your company data and provide access to certain files and folders to only a few employees. Your business experiences high employee turnover. You have more than 5 employees. A secure, complete backup of all of your critical business data is needed. A central information repository for your employees would be helpful. You want to have a cohesive email solution using a single domain address (i.e., jack@yourcompany.com, megan@yourcompany.com).

Think of the cost of implementing a network as an investment in your business. As your business grows, implementing a computer network will help your employees share information and resources, and in the long run, will play a major role in the successful growth of your business.

Computer Networking Solution for Small Business

2009-03-20T17:56:00.002+08:00

Computer Networking Solution

Many provisions of the computer network as a basis for small businesses in the physical world of transport. Some examples of these terms in its ports, hubs, bridges, switching and routing. However, this comparison is not unwarranted, since they have the same interest in the development of the information age, such as transport of the industrial age. Both networks and transportation system is a very good infrastructure.

Computer Networks connect computers:
Basic shape of most computer networks began to connect two electronic devices to transfer data between them. Third equipment only to reporting. However, connecting a printer to the computer using a USB cable is not a network. This will be a part of or in connection with the router or switch. The emergence of the Internet has forced most companies to think about computer networks solution. No matter how small businesses operate, you have networks for advertising, e-mail and online marketing of your products and services. If you do not have a good network of computers, your competitors leave you in contact with potential customers.

The biggest advantage is the sharing of files:
Sharing files is perhaps the most discussed in the core network. Sharing files is a centralized organization of files on a network server. Availability of all files in a place that makes the management of documents and data easier. You can also prevent the nuisance caused by the work inconsistent between different departments of the company. New versions of operating systems provides vast network control to the administrator. It is in complete control of a person can access a particular file or not.

Sharing printers save time and money:
A second important component of basic computer networks solution for small businesses to share printers. It saves a lot of time and money you would have spent for the purchase and maintenance of printers. Printers connected to the computer more features than that connected to one computer.

E-mail:
We must also learn the importance of e-mail to the full understanding of the fundamental principles of computer networks for small businesses. E-mail group facilitates the rapid and efficient communication among employees. Small businesses can also improve their programs, tasks and contacts management with the help of the group or internal e-mail. In addition, in the house of the production of documents rather than faxing as a group e-mails are less expensive and easier at an incredible rate.

Computer Networking Solutions: Don't let XP Service Pack 3 hose your system

2008-09-11T15:56:00.001+08:00

Computer Networking Solutions.

Scott Dunn from windowssecrets.com writes about problem with Windows XP Service Pack 3. He says “from the moment Microsoft released it, Service Pack 3 for Windows XP has been the subject of almost daily reports of bugs, incompatibilities, and general headaches.

You can install SP3 with confidence — providing you take certain precautions — or, if you prefer, use Windows' Automatic Update settings to keep the service pack off your system.”

Read the full story at http://windowssecrets.com/comp/080911

He also explains about making an upgrade decision that works for us. He says, In light of these and other problems, you may wonder whether you ever want SP3 at all, especially given that many of its enhancements focus on networking and IT-level administration. He advice us to consider about think security, consider support and be prepared. For full story at http://windowssecrets.com/comp/080911

Lastly he gives step on how to remove SP3 from your automatic updates.
This is the step:

If you decide you don't want SP3, Microsoft offers a tool for suppressing the automatic installation of the service pack. The Service Pack Blocker Tool Kit won't prevent you from downloading SP3 manually from the company's site, nor will it stop you from installing the patches from a CD or DVD. All it does is stop the service pack from being installed via Windows' Automatic Updates.

In addition, the Service Pack Blocker postpones the installation for only a year from SP3's release date last April.

Surf over to Microsoft's Service Pack Blocker download page and click the Download button for SPBlockerTools.exe. Click Yes to accept the license agreement and type in the path to the folder where the files will be stored (click the Browse button and navigate to the folder if you want to avoid typing).

Now open the folder containing the extracted files and double-click SPBlockingTool.exe. A command prompt window appears for a few moments and displays the statement "Action successfully completed." Unfortunately, that doesn't tell you very much. The action the message refers to is the addition of a Registry entry instructing Windows Update not to send you SP3. (The same setting on Vista blocks SP1.)

If you want to see the code that is added, do the following:

Step 1. Choose Start, Run. Type regedit and press Enter.

Step 2. In the Registry Editor, navigate in the left pane to this entry:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ WindowsUpdate

Step 3. With the WindowsUpdate icon selected in the left pane, look in the right pane for a key named DoNotAllowSP.

If you later decide you want Automatic Updates to offer you Service Pack 3, simply select the DoNotAllowSP key and press Delete (or click Edit, Delete).

If you're concerned about editing the Registry (which involves risks of its own), the Service Pack Blocker can also undo the block:

Step 1. Choose Start, Run. Type cmd and press Enter.

Step 2. At the command prompt, either type the path to the SPBlockingTool.exe file, or drag the file into the command prompt window and let Windows do the typing for you.

Step 3. At the end of this command, type a space followed by /U and press Enter.

Once again, you'll see the "Action successfully completed" message and Windows Automatic Update will no longer be blocked from installing the service pack on your system.

The other tool included with the download, SPreg.cmd, is a batch file useful for administrators who want to block the service pack on remote computers; this utility requires that the machine name be specified in the command line.

Even though most of SP3's problems should now be in the past, these precautions can help ensure that you aren't one of the service pack's installation victims.

Computer Networking Solution: Does Restore function restore everything?

2008-09-10T09:15:00.002+08:00

Computer Networking Solution: Does Restore function restore everything?

All of us know that Windows has RESTORE function. But does it really restore everything. Read below for some info.

To give a simple answer to the question,
Yes, Microsoft system restore sometimes do not "fix" everything.

OK, now a little more detail...
It is designed to only make "restore points" at certain specific times "it thinks" are important AND it then it only protects a VERY limited sub-set of MS stuff that MS uses inside the OS...
Note that making or storing an "MS Restore Point" can be done manually at any time, up to the limitations of "allowed space" it was assigned (or set to...) At that point, it starts to
"get rid of" older restore points.

It is NOT (and was not designed to be) an Image Program that would take a snapshot of the entire computer "as of" a certain point in time and restore the entire HD contents to the condition at that time.

Someone else will likely give good links to WEB sites that can explain this in much greater detail, but for now, if you are "sure" you used a MS Restore Point before the problem first
"happened", I believe you need to "fix" the original problem instead. As John has said, someone on the list will be happy to help with that if we can.

Restore does not always fix a problem. Even worse, sometimes you fix a problem only to have it re-develop from a restore file. A lot of anti-virus and anti-malware programs ask you to disable system restore during the fix process so that you will not become re-infected...

New Phishing Technique..Beware!!! (Computer Networking Solution)

2008-07-31T08:50:00.005+08:00

Computer Networking Solution: New phishing technique.... Beware!!!

We all know or at least heard about phishing. The tipical example for phishing is you received email from your bank saying they are updating customer database and want you to logon to your bank account and update your record. In the email there is a link for you to click that look like from your bank. When you click to the given link, it will not direct you to your bank website but you will redirect you to fake website that look similar to your bank website. When you logon to the fake website, it will collect your user ID and password than they will use it to the actual bank website...you know what happen next.

This is information from trendmicro.
Now there's new phishing technoque, no URL link or redirection within this email like the old phishing mail. So how the new phishing work? You receive email and if the customer reply the mail, then they are “fish” by the phishing mail. So from this new phishing technique, the user awareness is very important to educate user on how to be more aware on nowadays security risk in order for them to avoid being “fish” by the phisher.

The phisher can hijack the legitimate domain name and this can avoid them to slip through our ERS filter and no URL or redirection to avoid being filter by our WRS. So it is time to promote the TAAS to educate our customer in handling today’s threat and awareness. Below is the sample email that use new phishing technique.

So please beware and always double check with your bank. share this with your friend.

Why I cannot Print???? (Computer Networking Solution)

2008-07-17T17:19:00.003+08:00

Computer Networking Solution

One of common problem that I face in daily job is printer cannot print. By the way I work in IT department and one of my jobs is to settle user computer problem.

So, back to the printer problem. Normally user will call and say “I cannot print…why?”, User also will say, “This morning I can print….why now I cannot print?. User will call direct to IT people when they face problem.

Normally when I received that call, I will ask, is there any error message? They will say “ I don’t see any error message” or “Too long for me to read” or “I don’t understand what it says”. I may ask another question in order to rectify the problem over the phone. Some user don’t like it and simply say “You just come over here and settle my problem”.

So basically, when we face problem with Computer, look at the error message, try to understand it and follow as instructed. If you have no idea what it says, presses the ‘print screen’ button and paste to excel or words. Pass the file to your IT guys. The message is important for IT people to understand about the problem and solving process will become faster.

You can troubleshoot the problem by you self by doing simple check.

1. Check weather the printer was installed in your Computer or not? This may sound strange but for me this is what you should check first.( For WinXP SP2 – Click Start -> Printers and Faxes)
2. At the same place also, check the status of your problem/default printer, is it ‘ready’ or ‘offline’? Is the printer icon blur or not? If ‘ready’, means and the printer icon is not blur, means the printer is OK, you should be able to print. If you cannot print, the problem is not with the printer, look at others. If the printer status is ‘offline’ and the printer icon is blur, than you need to make the printer online.
a. If it is a network printer ( the printer has it own IP Address )- Check weather the printer is on or not. Check also for any error message. From the message start your troubleshooting.
b. If the printer is ‘network’ printer but connected to other computer in your office LAN(Local Area Network), please check if the computer that the printer connected to it is on or not? Try to print from the computer that the printer connected to it. You will not able to print to that printer until the computer that the printer connected to it is able to print.
3. After you try all, but still not working than call your IT guy.

For my case, the message that I receive is 'too many connection'. So I just reset ( on and off ) back the printer and the user is able to print as normal. :)

10 tips on how to help reduce spam: Computer Networking solution

2008-06-25T17:47:00.003+08:00

Computer Networking Solution: This article is taken from Microsoft website, and it’s a good article and I want to share with all of you. This is because SPAM is never ending story(at least at this time)

At the moment what we can do is try to reduce it by practicing simple method that is listed below. We also should change our way in handling our email address. Do you know why people like to SPAM, for me because it’s work. Many of us give good responding to SPAM. So it’s time to change and share this info with your family, friends and colleague.

10 tips on how to help reduce spam
Applies to: Microsoft Office Outlook 2007

Follow these guidelines to help lower your risk of receiving junk e-mail.

1. Take advantage of the Junk E-mail Filter in Microsoft Office Outlook 2007 Office Outlook 2007 helps to mitigate the problem of spam by providing the Junk E-mail Filter, which automatically evaluates incoming messages and sends those identified as spam to the Junk E-mail folder.

2. Block pictures in HTML messages that spammers use as Web beacons Office Outlook 2007 has an additional anti-spam feature. By default, this feature blocks automatic picture downloads and other external content in messages if the content is linked to a server. If you open a message that has external content when this feature is turned off, the external content downloads automatically, inadvertently verifying to the server that your e-mail address is a valid one. Your e-mail address can then be sold to a spammer. You can unblock external content for messages that come from sources that you trust. For details, see Block or unblock automatic picture downloads in e-mail messages.

3. Turn off read and delivery receipts and automatic processing of meeting requests Spammers sometimes resort to sending meeting requests and messages that include requests for read and delivery receipts. Responding to such meeting requests and read receipts might help spammers to verify your e-mail address. You can turn off this functionality. However, read and delivery receipts and automatic processing of meeting requests are useful features that you should not be afraid to use within a secure corporate network.
Note Delivery receipts can be turned off only by your e-mail server administrator.
Turn off read receipts
1. On the Tools menu, click Options.
2. Click E-mail Options.
3. Click Tracking Options.
4. Under Use this option to decide how to respond to requests for read receipts. Only applies to Internet Mail accounts, click Never send a response.

Turn off automatically acceptance of meeting requests
5. In Outlook, on the Tools menu, click Options, and then click Calendar Options.
6. Under Advanced options, click Resource Scheduling.
7. Clear the Automatically accept meeting requests and process cancellations check box.

4. Limit the places where you post your e-mail address Be cautious about posting your e-mail address on public Web sites, such as newsgroups, chat rooms, bulletin boards, and so forth. When visiting public sites, you might want to use an e-mail address that is different from your main e-mail address. Remove your e-mail address from your personal Web site. Whenever you list or link to your e-mail address, you increase your chances of being spammed.

5. Review the privacy policies of Web sites When you sign up for online banking, shopping, or newsletters, review the privacy policy of the site carefully before you reveal your e-mail address or other personal information. Look for a link or section (usually at the bottom of the Web site's home page) called "Privacy Statement," "Privacy Policy," "Terms and Conditions," or "Terms of Use." If the Web site does not explain how your personal information will be used, consider not using the services at that site.

6. Watch out for check boxes that are already selected When you shop online, companies sometimes add a check box that is already selected, which indicates that it is fine with you if the company sells or gives your e-mail address to other businesses (or "third parties"). Clear this check box so that your e-mail address is not shared.

7. Don't reply to spam Never reply to an e-mail message — not even to unsubscribe from a mailing list — unless you know and trust the sender, such as when the e-mail message comes from a service, an online store, or newsletter that you have signed up with. Answering spam just confirms to the spammer that your e-mail address is an active one.

8. If a company uses e-mail messages to ask for personal information, don't respond by sending a message Most legitimate companies will not ask for personal information to be sent in e-mail. Be suspicious if they do. Such a request could be a spoofed e-mail message disguised to look like a legitimate one. This tactic is known as phishing. If the possible spam appears to be sent by a company that you do business with — for example, your credit card company — then call the company to verify that they sent it, but don't use any phone number that is provided in the e-mail. Instead, use a number that you find by using other means, such as directory assistance, a statement, or a bill. If the request is a legitimate one, the company's customer service representative should be able to assist you. The Junk E-mail Filter also includes phishing protection to help identify and disable suspicious messages.

9. Don't contribute to a charity in response to a request sent in e-mail Unfortunately, some spammers prey on your goodwill. If you receive an e-mail appeal from a charity, treat it as spam. If the charity is one that you want to support, locate their telephone number or Web site to find out how you can make a contribution.

10. Don't forward chain e-mail messages Besides increasing overall e-mail volume, by forwarding a chain e-mail message you might be furthering a hoax — and meanwhile, you lose control over who sees your e-mail address.

Eventhough this article meant for Microsoft Office Outlook 2007, but some of it we can practice it even we use others email software. This guide is not difficult to practice, so let us start practicing it, and don’t forget to share with your family, friends and colleagues. ( Computer Networking Solution )

You are installing FREE AVG on your PC which was working
fine previously with C: and D: drives shown and working well.

Strangely the system lost the D: drive (cdrom) not showed.
You could not access it at all. You cannot see it from BIOS and Windows XP Home control
panel/systems. You also reboot your PC more that 2 times but the result still the same.

You also do virus scan and scan for spyware but no found nothing.

No body opened the tower to tamper with power and IDE cables.

What would you do?

Computer Networking Solution: Basic about BIOS

If the drive is not showing in BIOS, you have a simple hardware
failure. The fact that you were installing a windows based program like
AVG is not relevant. It is just one of those things. BIOS is the
basic hardware detection area of your motherboard, and this level of
device management is not even "aware" that a hard drive exists that
might have Windows on it with AVG installed. That process starts at the
end of Power On Self Test (POST) when the system gets around to looking
at the hard drive to see if it is bootable. But the CD drive has
already been detected (or not) by that time.

Computer Networking Solution to try

You can try to do ‘Cold Boot’, a full electrical shut down.
You even need to unplug the power cord for a minute or two just to be sure
"everything" gets back to a "known state". Totally discharge the electricity from the system

Then Boot to the BIOS.

If it is still missing, and it is set to auto configure,
OR the settings are locked for it to be assigned properly,
you will have to open the case.

Nothing you installed "inside Windows" can make a CD-ROM drive
disappear "IN THE BIOS".

DO NOT open the case if the computer is under warranty as
that might kill the warranty also...

Gently remove the proper data cables and power cables and re-seat
them a time or two. THEN check that ALL cables are seated properly.

Computer Networking Solution : Attention
Anytime "anyone" tells you to open a case, you need to know about
proper anti-static precautions.

Get anti-static "wrist thing", or touch bare metal inside the
case to drain any static charge from yourself while working.
Don't work in an area known to cause lots of "sparks" or "snaps"
(when you walk across the rug, etc... . Unless you are "extra"
careful... (That is hard to define unless you are there...)

If you have a high static area it is better to "stay out"...

Good luck – Computer Networking Solution

Microsoft Outlook 2003 error (Computer Networking Solution)

2008-06-04T09:29:00.002+08:00

Computer Networking Solution: Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or wrong version
This morning when I want to open Microsoft Outlook 2003 I got below message “Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or wrong version.” It also suggests reinstalling the Microsoft Office Outlook 2003. I did as suggested, I reinstall Microsoft Office Outlook 2003. After reinstall, I open the Microsoft Outlook 2003 BUT I still received the same message “Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or wrong version”

I found one forum at http://www.planetamd64.com , they discuss about this issue. Here are the three solutions that the members give.

Solution 1
I was having numerous overall system problems with Office 2007 so I uninstalled the Beta. I had installed it beside 2003 and not as an upgrade. Everything was back to normal except Outlook which I had no option but to upgrade to the 2007 version. After uninstall, I kept getting an error concerning MAPI32.DLL being corrupt or the wrong version and to reinstall Outlook, which I did (I had a full backup of my folders and emails). After the reinstall, I was still getting the same error and Outlook would not open. I did a search and found that the file listed in the error was not MAPI32.DLL but instead MSMAPI32.DLL.

The folder was Program Files (x86)\Common Files\System\MSMAPI\1033. The non-reverted file was 50 KB in size and had a 5/2006 Date Modified. The correct file should be 1,326 KB with a 6/2004 Date Modified. I copied the correct file from another installation and pasted it into the folder listed above. Outlook then opened and the program was just as it was prior to the upgrade to 2007. If anyone has this same problem and you don't have another installation to copy the file from, let me know and I will get it to you. I don't want to take up space at PAMD64 with that size file as an attachment...talker

Solution 2
No need to download any files at all. Just rename the MSMAPI32.DLL to MSMAPI32.DLL.old found below

Drive:\Program Files\Common Files\System\MSMAPI\1033\MSMAPI32.DLL

Start outlook2003 and it reinstalls the DLL and you don't loose anything.

Solution 3
I would reinstall 2007. Export message store, address books, etc. Uninstall 2007. Reboot. Reinstall 2003 and patch it. Import everything back in

I use solution 2 and it worked like a charm. After I rename the file and start Microsoft Office Outlook 2003, the Microsoft Office Outlook 2003 does the short installation and my Outlook open with all the email remain.

I never try the 2 method as I have no time. Maybe you can try it and reply to me.

Cheers

A Magic Number To Avoid Spam?( Computer Networking Solution)

2008-05-30T09:22:00.003+08:00

Spam is a common topic today, all computer user know what spam is? Do you know why people do spamming? The answer is because this method works. It' works in generate sales, membership, opt-in list and etc. This time Computer Networking Solution find an interesting question ask by user in www.pcmag.com. Neil J. Rubenking answer the question.

Q. I was told that e-mail addresses with numbers in them get less spam. Is this true? Is it worth changing my e-mail address for?—Linda Young

A. Spammers get a hold of e-mail addresses in roughly a zillion ways. When you buy something at a small, lesser-known online store there's a decent chance they will sell your address to spammers. Even if it's a big, reputable store that gets your cash, the store's records could still be stolen or leaked. Sign up for a newsletter? Your address could certainly get sold. Ever write comments in blogs or discussion forums that display your e-mail address? Spammers have tools that "scrape" those addresses. That is, they process the text on the page and strip out anything that looks like an e-mail address.

In any of the above scenarios—and plenty more—it doesn't matter what your address is. The one technique your number idea could foil is what is called a "dictionary attack." The spammers get a list of common first names, a list of common last names, and a list of ISP e-mail domains they want to try. Then they generate all possible combinations and fire off a gazillion messages (at next to no cost). Anyone unwary enough to respond gets moved to a list of "live" addresses that can be sold to other spammers. Yes, an address like Joe142857Blow@domain.com would be more resistant to this attack than plain JoeBlow@domain.com.

In general, when you change your e-mail address, it takes the spammers a while to catch up. So any change, with or without a number, will bring temporary relief. If you also change your habits to guard this new e-mail address more carefully, it will take the spammers longer to get you back on their lists. But sooner or later they always seem to find us.(end of answer)

So basically at the moment spam email will still come unless we take precaution. Computer Networking Solution will discuss about it later.

Wiindows XP SP3 Problem: Need urgent attention

2008-05-30T08:17:00.004+08:00

Weather you are home user or coorporate user, you should pay attention to this news. This time Computer Networking Solution bring you "Windows XP Service Pack 3 Problems require attention"

Brian Livingston from www.windowssecrets.com mention there is a problem with Windows XP SP3. Susan Bradley in the same news letter encourage us to wait on installing XP SP3 if we don't have urgency. Brian Said the problems with XP SP3 include AMD-based Hewlett-Packard desktop computers constantly rebooting and Symantec antivirus products developing strange behaviors. It makes him wonder which executives at HP and Symantec were supposed to test these companies' products during the months-long beta releases of SP3.

Base on Susan analysis Antivirus software from Symantec Corp. may cause the installation of Service Pack 3 for XP to corrupt the Windows Registry by adding unnecessary keys.

Symantec advises users to disable the SymProtect security feature of its products before applying XP SP3.

Thanks to Susan for th analysis and give us solution. Below is her message.

A Registry fix is needed by the latest XP patch

The latest in the continuing series of problems related to Windows XP Service Pack 3 involves Symantec's Norton AntiVirus. The company recommends that users disable the program's self-protection feature before installing XP SP3.

In a post to Norton's support forum, Symantec senior SQA manager Reese Anschultz suggests that customers disable the SymProtect feature found in various Symantec security products:

• To do this in Norton Internet Security 2008 and Norton AntiVirus 2008, uncheck Turn on protection for Norton products on the Options pages of these programs prior to installing XP SP3. Once the service pack is in place, return to the Options page and re-enable this setting.

• In Norton SystemWorks 2008, open the Advanced Options under Settings, click Next, choose Norton SystemWorks Options, and select the General tab. Uncheck Turn on protection for my Symantec product.

For other Norton products, read Anschultz's post, which comments that other third-party security products may also cause problems unless some functions are disabled before SP3 is installed.

Some Windows Secrets readers have had to remove Norton AntiVirus completely before deploying XP SP3. While taking this step may sound extreme, reader Bert Smith from Australia was told by a Symantec engineer that he should "follow these instructions" to use the Norton Removal Tool to uninstall Norton Internet Security 2008 before he deployed Vista SP1!

Given what we now know, it may actually be wise for you to uninstall Norton antivirus products prior to deploying SP3, which is XP's latest — and last — service pack. Thanks to reader Jan Levine for identifying this issue in the Microsoft TechNet Forums.

If you find that installing XP SP3 has corrupted your Symantec security product, my fellow MVP Bill Castner has devised a downloadable Registry fix (scroll down the page until you see My "Fix"). Castner first identified this issue along with Jesper Johansson, who's been tracking the XP SP3 problem in his blog.

Johansson also provides a patch for AMD computers that XP SP3 causes to reboot constantly. I described this problem in my May 22 column. For more information, see the following item.

A cure for XP SP3's never-ending reboots

If you're one of the folks whose AMD-based PCs constantly reboot after applying XP SP3, here's how you can recover.

When the system is first booting, press F8 to enter Windows' Safe Mode. Log into the Administrator acccount, click Start, Run, type cmd, and press Enter. When the command window opens, type the following command (don't forget the space after the equals sign, which is required):

sc config intelppm start= disabled

The problem is caused by the presence of Intel drivers on AMD-based systems. Follow the above steps only if you know your PC uses an AMD processor; doing so on an Intel-based machine could render the system unusable.

To determine which processor your system uses, open the Control Panel's System applet and click the General tab. (See Figure 1.)

Figure 1. Open the System applet in Control Panel to verify the type of processor your PC uses.

If the processor listed in the window is "Intel," do not enter the command shown above. An Intel-based system that constantly reboots may be having an unrelated problem. It might be caused by conflicts with antivirus products, as described in my previous item, or something else entirely that no one has yet identified.

As I wrote in my May 22 column, there's no rush to install XP SP3. Wait until we know more about these kinds of conflicts.

Thanks again to Susan for this valuable information. Computer Networking Solution will update this issue from time to time.

How to download Youtube video.

2008-02-25T14:31:00.002+08:00

The note below I took from yahoo group called simplycomputer2@yahoogroup.com. A person post a question to the group about how to save a youtube video to personal Computer. One of the group member named “ordinaryfoolisnj” give below answer.

There many programs to help you save Youtube videos, as well as amethod that uses the Internet Explorer browser internet files to do so. I use a program formerly called "KeepIt!" -- now available asVideoDownloader -- to save Youtube vids: http://javimoya.com/blog/youtube_en.php Instructions on its very simple to use interface are on the site, but briefly, you go to Youtube and start the video that you wish to keep, then copy the website address and paste it into the box indicated atthe website above. They then present a video download link for you. You click the download link, then save the video as whatever name you wish plus the .flv extension. Its key that you add the .flv extensionto the end of the new file name. You can "get" your Youtube video directly via the website abovewithout downloading anything, or with the plugin for FireFox. I've used them both successfully. The other way to get the video if you're using Internet Explorer, is to:

a. Let the video load completely (let it run once).

b. Go to your C drive and navigate to Documents and Settings, name ofthe account you're in, Local Settings, then Temporary Internet files.This shows all of the web information that has downloaded into the IEbrowser in order for you to view them.

c. Find a file that starts with name "GetVideo?vid..." (it should bea fairly large sized file).

d. Drag it to your desktop.

e. Rename the file to whatever you want with an .flv extention (thisis CRUCIAL).

Viola.

Now you need a flash content player. I use a player called FLV Player to view my downloaded Youtube videofiles (simply drag and drop the "whatever the name.flv" file from where its stored on the hard drive or CD onto the open FLV window). http://www.download.com/FLV-Player/3000-2139_4-10467081.html.

Most of the videos I think are not high enough quality to convert to DVD burnable files (I usually burn the .flv files and the player toDVD or CD to view later as data files). But there is a free program called Super that some guys and gals hereon the list have recommended to convert the .flv file to mpeg, etc.http://www.erightsoft.com/SUPER.html I've given you a lot of information, but don't be confused as allprocesses are very, very easy once you're run through it once. I hope that this helps,Nancy J

Make your computer dual-boot Vista and XP

2008-02-21T08:19:00.004+08:00

I received this article from Windows Secret Newsletter. I found it is a great article. So I put on my blog so my friends, readers and for myself to refer next time. Because we don't know when we need it. Frankly speaking I haven't try this tip's. I will try next week after I received my new Dell Latitude Notebook. By the way this article was written by Scott Dunn.

"It's getting harder to buy a new computer with Windows XP installed and — after Microsoft stops selling XP on June 30, 2008 — it will become nearly impossible. Fortunately, you can have your XP cake and eat your Vista, too, by setting up your system to boot between the two operating systems.

Add an XP option to your new Vista system.

If a new computer arrived in your recent past, or you plan to buy one in the near future, chances are it will come with Windows Vista installed. Although some manufacturers still give you the option of getting XP on your new system, that option is likely to dry up for most consumers later this year when Microsoft stops selling Windows XP. If you're not ready to dive into Vista all at once, there is an answer: set up your Vista computer to dual-boot between Vista and XP. In this article, I'll tell you how to make your PC give you a choice between Vista and XP every time you start up. In a separate article coming soon, I'll give you some additional tips that save disk space on a dual-boot system. Although some sources, such as Computer Shopper Magazine, advise that you need an add-on product like VistaBootPro to dual-boot, you can accomplish the same thing without any additional software other than the two operating systems. Before starting, make sure you have your Windows XP install discs ready as well as your Windows Vista DVD. In addition, it's a good idea to make a complete system backup before beginning an operation like this. Once you've laid that groundwork, you're ready to go to work:

Step 1. In Vista, click Start, type diskmgmt.msc, and press Enter. Click Continue if prompted by User Account Control.

Step 2. Right-click a drive and choose Shrink Volume. Specify the amount to shrink, which in this case is the amount you want for your XP partition. At a minimum, you'll need around 2.5GB for XP Pro SP2. I suggest you select a larger partition to leave room for updates and other files that may need to be on the same drive as XP. Because I wanted a 5GB partition, I typed 5000 (representing 5,000 megabytes) in the available box. Click Shrink.

Step 3. Right-click the newly available area and choose New Simple Volume. Follow the steps in the wizard to assign a drive letter now, or wait until the next step. When prompted, check Perform a quick format to format the volume with NTFS.

Step 4. When the wizard is done formatting the new volume, you can assign or rearrange drive letters as needed. For example, changing drive letters may also put your CD/DVD drive in a more logical order.To do that, right-click a volume or the CD/DVD drive and choose Change Drive Letters and Paths. If a volume hasn't got a drive letter yet, click Add. Otherwise, select the drive icon in the dialog box and click Change.If you're rearranging the letters on existing drives, you may need to change the drives in a particular order. Or you may need to give a drive a temporary letter (such as Z) to free up a letter for another drive; you would change the Z drive to something else later. Make your selection and click OK. Repeat for other partitions or drives until you have the order you want.

Step 5. When you're done with your partitioning chores, exit Disk Management. Insert your XP disc into the drive and restart your system, booting from that disk.

Step 6. Follow the steps to install XP. When asked for the target drive, select your new partition and press Enter. Because you already formatted this partition with NTFS, you can skip the formatting step. At the appropriate screen, arrow down to Leave the current file system intact (no changes) and press Enter. Continue the installation process until it's finished and XP has started.

Step 7. Your system now boots to XP, so we'll need to do some fixing to set up a boot menu. Insert your Vista DVD and restart the computer from it. Click Next in the first screen.

Step 8. Don't click Install when prompted! Instead, click Repair Your Computer in the lower-left corner.

Step 9. When the System Recovery Options dialog appears, make sure Microsoft Windows Vista is selected and click Next. In the next dialog box, select the Command Prompt option at the bottom.

Step 10. In the command-prompt window, type the following commands and press Enter after each one:

bootrec.exe /fixMBR
bootrec.exe /fixBoot

Step 11. Close the command prompt and click Restart.

Step 12. When your computer has booted into Vista, click Start, type cmd.exe, and press Ctrl+Shift+Enter to make the command window open with elevated privileges. Click Continue, if prompted by User Account Control.

Step 13. Type the following commands in the command window, one at at time, pressing Enter after each one. After each command, you should get the response, "The operation completed successfully." A response of, "The specified entry already exists," is OK, too. If not, retype your command to make sure you've entered it correctly. If Vista is installed on a drive other than c:, change the first command below to use the proper drive letter. The curly braces around {ntldr} in each command must be typed exactly as shown:

bcdedit -set {ntldr} device partition=C:
bcdedit -set {ntldr} path \ntldr
bcdedit -displayorder {ntldr} -addlast
bcdedit -set {ntldr} description "Microsoft Windows XP"

That's it! The next time you restart your system, you should be see a prompt that will let you choose between Vista or XP. Select the one you want and press Enter.

How to customize your boot menu

When you start your dual-boot system, the menu will appear for a few seconds. If you don't press any keys, eventually Windows Vista will start. Fortunately, you can change this if you don't want Vista to be your default operating system. You can also customize the waiting period before the default kicks in.

Here's what to do:

Step 1. Click Start. Type systempropertiesadvanced and press Enter. Click Continue, if prompted by User Account Control.

Step 2. Under Startup and Recovery, click Settings.

Step 3. At the top of the dialog box, select the operating system you want to start by default.

Step 4. In the box to the right of Time to display list of operating systems, specify the number of seconds for the options to stay on screen. Click OK. Microsoft provides documentation of Vista's bcdedit command and its parameters in an article in the Windows Vista Technical Library."

Hope you all can try it...

My experience downgrading Windows Vista to Windows Xp.

2008-01-11T01:36:00.000+08:00

My company bought a brand new HP notebook with Windows Vista installed. Due to business reason I have to downgrade it to Windows Xp Pro. I thought it is straight forward process, so I just grab my Windows Xp Pro installer( Original) and put it inside the DVD drive. I restart the notebook and make sure the notebook boot from Windows Xp CD. As normal I reach to the screen where I have to select weather to install, repair or quit. I hit the enter key for install, and the next message I get is the installation cannot continue because no hard disk detected. I thought I make mistake and repeat the process. Again I received the same message. So I know something not right. I do a search using google and manage to get a few opinion from forum. I tried and one method work for me. The process that I did is,

1.Make sure the new HP notebook has driver for Windows XP Pro. I check with HP website and yes, there is driver for Windows Xp Pro. So I download and keep the driver in my external Hard Disk.
2.With the Windows XP CD still inside the DVD drive, I turn on the notebook
3.Keep tapping the F10 key when the Compaq logo appears. This will take you to BIOS Setup Utility.
4.Using arrow key I go to “System Configuration tab”.
5.Under that select you will see SATA Native support. The default value is enable, so I disable it.
6.Press F10 to "Save and Exit" the BIOS.
7.Click on OK/Yes to confirm the changes.
8.Restart the notebook.
9.The notebook boot up from Windows XP CD.
10. As normal, I reach to the screen where I have to select weather to install, repair or quit. I hit the enter key than I get the screen that show the partition.
11.After that I just do as normal and I manage to install Windows XP Pro. :-)

4 things to do when use public computer.

2008-01-02T09:38:00.000+08:00

Public Computer is the computer that we can find it libraries, Internet cafes, airports, copy shops and other place that allow people to access internet. It is very convinience, but we must take precoution. Here are the precoution list.

1. Don't ever save your logon information.
Always log out of Web sites by clicking "log out" on the site. It's not enough to simply close the browser window or type in another address. Many programs (especially instant messenger programs) include automatic login features that will save your user name and password. Disable this option so no one can log in as you.

2. Don't leave the computer unattended with sensitive information on the screen.
If you have to leave the public computer for a while, log out of all programs and close all windows that might display sensitive information.

3. Don't forget to erase your tracks.
Web browsers such as Internet Explorer keep a record of your passwords and every page you visit, even after you’ve closed them and logged out.

To disable the feature that stores passwords.
Before you go to the Web, turn off the Internet Explorer feature that "remembers" your passwords.
1. In Internet Explorer, click Tools, and then click Internet Options.
2. Click the Content tab, and then click AutoComplete.
3. Click to clear both check boxes having to do with passwords.

To delete your temporary Internet files and your history.
When you finish your use of a public computer, you should delete all the temporary files and your Internet history.
1. In Internet Explorer, click Tools, and then click Internet Options.
2. On the General tab, under Temporary Internet files, click Delete Files, and then click Delete Cookies.
3. Under History, click Clear History.

Don't enter sensitive information into a public computer.
These measures provide some protection against casual hackers who use a public computer after you have. But keep in mind that an industrious thief might have installed sophisticated software on the public computer that records every keystroke and then e-mails that information back to the thief. Then it doesn't matter if you haven't saved your information or if you've erased your tracks. They still have access to this information. If you really want to be safe, avoid typing your credit card number or any other financial or otherwise sensitive information into any public computer.

And lastly watch for over-the-shoulder snoops.
When you use a public computer, be on the look out for thieves who look over your shoulder or watch as you enter sensitive passwords to collect your information

7 Tips for Secure Home Network

2007-12-29T08:17:00.000+08:00

When you are planning to do home networking or your house already has networking, you should consider about security of your network. Security here means you don't want other people use your network resourses( use your wireless internet connection ), put spyware to your home PC's so it can monitor your activity, and the worst part is distribute virus. Here 8 tips on securing your home network;

1. Make sure to install virus protection software on all PCs on your network, and make sure they are updated as routinely as possible. You can buy or yse free antivirus like AVG.

2. Enable Microsoft file and printer sharing with extreme caution. If you set permissions incorrectly, outsiders can locate your PCs more easily and gain access to files on your hard drives. Consider enabling port blocking on your firewall.

3. If you have children using your network, consider setting up some form of Web filtering through either a software-based firewall (like McAfee Internet Security or Norton Internet Security ) or a hardware firewall (like the D-Link or Linksys Firewall Router).

4. You can also install monitoring software that can log internet activity like ccproxy. You can use it for free for 3 PC's.

5. If you choose a hardware firewall, make sure it includes Stateful Packet Inspection (SPI). SPI inspects the content of packets (not just the source and destination addresses and ports) to determine whether to allow them access to your network.

6. If you're building a wireless network, be sure to turn on WEP (Wired Equivalent Privacy) on your wireless router or access point. If you put open, your neighbour can use your internet connection for free :)

7. Periodically check for heavy traffic on your router's LEDs and whether each PC's log files contain new entries you are unfamiliar with. These factors could indicate that someone has hijacked your PC and is using it for DDoS attacks or other malicious activity.

8. At night, shut off your wireless router—especially if you live in a densely populated area—and your PCs. What is not available cannot be hacked.

Computer Networking Solution: What hardware you need?

2007-12-03T23:15:00.000+08:00

What hardware or equipment that we need to create or built network? Basically we need three equipments:

1. Network Interface Card
2. Network Cable
3. Network Hub/Switch

1. Network Interface Card.
It is a electronic circuit card inside any network computer. It is also called NIC in short. Most of motherboard nowadays has Network Interface Card built in with motherboard. This will make easy for us since we don't have to purchase additional NIC. But if your motherboard don't have it, don't worry because the price for NIC nowadays is cheap...trust me its cheap. The NIC has a slot that we can insert connector called RJ45. This is for wired situation. For wireless environment, the NIC has a small antenna that capture the signal send by access point. I will discuss about wireless in future. The most common NIC that I use is from 3-Com and D-Link. The are many brand in the market, just ask your computer shop.

2. Network Cable.
The network cable is what actually connects the computers together. It plugs into the network interface card at the back of our computer. The cable is called UTP cable. UTP is stand for 'unshielded twisted pair'. If you cut the cable, we can see 8 cable with different colour. Every two cable is twisted together and the cable is not shielded. There is a cable that shielded to be use in certain condition. At this moment, don't worry about it. The UTP cable also has category, normally we use CAT5 or CAT5e or CAT6. The different is speed.

3. Network Hub/Switch.
If your network is set up using twisted pair cable, the network probably also has a network hub/switch. The hub/switch is a small box with a bunch of cable connector. Each computer on the network is connected by cable to the hub. The hub function is to connect all computer to each other.

Computer Networking Solution: What is network?

2007-11-26T00:02:00.000+08:00

Network is not something new, but I still want to talk about basic things.
I will explain what is network and why we need it. Network is nothing more than two or more computers connected together. Either by cable or wireless. As long as the two computer connected, the two computer we say is network together.

How the two computer connected? what network hardware we need to use? what setup we need to do?, I will explain next time. As I said basic thing first.

By the way why we need network? Why people start to say " we better to have computer networking system". It start when people want to share information. Without network, what we have to do is save/copy our file to floopy/CD/DVD/thumb drive and give to our officemate. He/She then will copy the file to his/her PC and open it. After he/she finish modified he/she will pass back the device to you. So this is the scenario.

If the computer is networked together, we don't have to do all those thing I mention above. So that the important to have computer network. All the computers that network together in office or house we called it Local Area Network or LAN.

The are a few type of network like star, mesh, bus etc, but I not going to discuss here because we are not taking exam like CCNA or Network+ or MCSE. Here I want to write about home networking and small business networking solution. Also don't confuse LAN with Internet
. The Internet is a huge amalgamation of computer network strewn about the entire planet.

Frankly, computer networks are a bit of a pain to set up,. So why bother? Because the benefits of having a network make the pain of setting one up bearable. Networks is about sharing. Specifically, networks are about sharing three things
1. Files.
2. Resources
3. Programs.

See next time.

Some examples of such terms are ports, hubs, bridge, switching and routing. However, this simile is not unjustified because networks have same importance regarding the boom of the information era, as the transportation to the industrial era. Both computer networks and transportation system require very sound infrastructure.

Computer Networking Solution is connecting the Computers: Most fundamental form of computer networking goes back to connecting any two electronic equipments for the transfer of data between them. Third equipment only helps the communication of data. However, connecting a printer to computer simply with the help of a USB cable is not called a network. It will be a part of the network if connected with router or switch. Advent of Internet has forced the most of the companies to think about the computer networking. No matter how small business you are running, you need to have computer-networking facilities for publicity, email and online marketing of your products and services. If you do not have a well-established network of computer, your competitors will leave you behind in contacting the prospective customers.

The Biggest Advantage is File Sharing: File sharing is perhaps the most talked about component of the Computer Networking Solution fundamentals. File sharing is simply centralized grouping and organization of data files on a network server. Availability of all the data files at one place makes managing documents and data easier. Furthermore, you can also avoid the inconvenience caused by the inconsistant scheme of work among the different departments of the business. The newer versions of the network operating systems give tremendous control to the administrator. He is in complete control whether a person can get access to a particular file or not.

Sharing of Printers Saves Both Time and Money: Second important component of the computer networking fundamentals for small businesses is printer sharing. It saves a lot of money and time that you would have spent on the purchasing and maintenance of printers. The printers connected to the computer network have more features than those connected to single computers.

Email: One should also learn the importance of email to get the full understanding of Computer Networking Solution fundamentals for small businesses. Group email facilitates fast and effective communication among the employees. Small business can also improve their scheduling, task assignment and contact management with the help of group or internal email. Moreover, in-house communication of documents is better than faxing because group emails are less expensive easier and unbelievably fast.
