How to Build a Computer Network System

 

A network allows multiple computers to send files and folders to one another, share a single Internet connection and print from the same printer. Although setting up a network used to be a challenging task, modern operating systems do most of the software configuration automatically, so setup is simple even for a novice user.
You will need to connect each computer to a router. This acts as a switching station, directing signals from and to the appropriate systems. Although a hub or a switch can be used instead of a router, a router is recommended because of its stability and more advanced features.

     Locate the router in a central location and plug it into a wall. If it has a power switch, turn it on. To share a high-speed Internet connection, such as DSL or cable, plug the modem's Ethernet cord into the Internet port on the back of the router. This will normally be labeled "Internet," "WAN" or "WWW."

     Connect an Ethernet cable into the networking jack on the back of each computer. Run the cables along a path that's out of the way and won't cause people to trip. Connect the other end of the Ethernet cables to any of the numbered ports on the back of the router. As each computer is connected, a new light on the front of the router should turn on.

     Power on all of the computers, and run the operating system's network configuration program. In Windows XP, for example, this is the "Network Setup Wizard" located under the "Control Panel." In Windows Vista, click "Network and Internet" under the "Control Panel," followed by "Network Sharing Center" and then "Setup a connection or network." Macintosh systems will normally configure the network by themselves.

     Walk through the steps in the installation wizard. It will ask you a few questions about the network, such as what type of Internet connection is being used. Finally, you will be asked if you want to enable file and printer sharing. If you say no, only the Internet connection will be shared among the computers. If you say yes, then all of the network printers and shared document folders will be available for each computer to access.
