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?
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?
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.

More on Computer Networking Solution
You may not know much about networking, what it can do? what is the benefit to have it?, how to do it?, when you need it? where to start and who to contact? No worries any more because here I give you a collection of good articles on Computer Networking Solution. I will also write an article about Computer Networking Solution. Enjoy article on Computer Networking Solution.
Computer Networking Solution is a process of sharing data and shared resources between two or more connected computers. The shared resources can include printer, Fax modem, Hard disk, CD - DVD Rom, Database and the data files. A Computer Network Solution can be divided into a small or local area network, a networking between computers in a building of a office (LAN), medium sized network (MAN), a network between two offices in a city and Wide network (WAN) a network between the computers, one is locally and the other can be thousands of miles away in any other country of the world.
WAN connectivity is achieved by a network device known as “Router”. The internet is the world’s largest WAN network, where millions of computers from all over the globe and connected with each other.
Networking is the practice of linking two or more computers or devices with each other. The connectivity can be wired or wireless. A computer network can be categorized in different ways, depends on the geographical area as mentioned above.
There are two main types of the computer network client-server and peer to peer. In the client server computing, a computer plays a major role known as server, where the files, data in the form of web pages, docs or spread sheet files, video, database & resources are placed.
All the other computers in the client/server network are called clients and they get the data from the server. In the peer to peer network all the computers play the same role and no computer act as a centralized server. In the major businesses around the world client-server network model is in major use.
A network topology defines the structure, design or layout of a network. There are different topologies like bus, ring, star, mesh, hybrid etc. The star topology is most commonly used network topology. In the star topology, all the computers in the network are connected with a centralized device such as hub or switch. Thus forms a star like structure. If the hubs/switch fails to work for any reason then all the connectivity and communication between the computers of a network will be halted.
In the Computer Networking Solution, a common communication language is used by the computers and the network devices and this language is known as protocols. The most commonly used and popular protocols on the internet and in the home and other networks is called TCP/IP. TCP/IP is not a singleprotocol but it is a suite of several protocols.
A network can be a wired or wireless and TCP/IP protocol can work both in types of network.
A data flow in a computer network can be divided into seven logical layers called OSI layersmodel that was developed by Intel and Xerox Corporation and was standardized by ISO.
1. Application layer
2. Presentation layer
3. Session layer
4. Transport layer
5. Network layer
6. Data Link layer
a. Media access control sub-layer
b. Logical link control sub-layer
7. Physical layer.
A network can be divided into different scales and ranges and it depends on the requirement of the network and the geographical location. Computer Networking Solution can be divided into Local Area Network, Personal Area Network, Campus Area Network, Wireless Local Area Network,Metropolitan Area Network and Wide Area Network.
There are several Computer Networking Solution connection methods like HomePNA, Power line communication, Ethernet and Wifi connection method.A network can also be categorized into several different types based on the services it provides like Server farms, Storage area networks, Value control networks, Value-Added networks,SOHO network, Wireless network and Jungle networks.

Either your business is small or big, knowledge of Computer Networking Solution is important. This is to make sure you can solve or do 1st level troubleshoot when you face networking problem. You should know some terms that use in Computer Networking Solution.
Many terms of the Computer Networking Solution fundamentals for small businesses have come from the physical world of transportation. 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.
