First Steps in Computer Networking – Get it Together

Computer networking can be a tricky. With different devices and protocols, things can get mixed up rather quickly. However, learning the basics should be manageable for the average computer user. Below explains the first networking building block — connecting computers to the network.

Until recently, the most common way to connect computers directly was with an Ethernet cable, or an Ethernet cable via a hub. However, wireless technologies make connecting even easier. Instead of a cable, think of a wireless network as having invisible, or radio signal, cables.

To connect computers in a wireless network, even if you don't have an internet connection, can be done very easily — no router required. If the computers have Wi-Fi devices, whether built in or added, you can create an "ad-hoc" wireless network by configuring the computers to ad-hoc mode.

Alternatively, if your computers have Bluetooth built-in or added, you can set up a simple network. Bluetooth data transfer speeds are slower (it uses a radio signal) and require computers to be closer together. But it's still an effective way of sharing information and is easily configured.

If your computers are more than a few years old, there's a good chance that they do not have Wi-Fi or Bluetooth built-in. And, unfortunately, older Microsoft operating systems don't support Bluetooth technology at all. If your computers do support Bluetooth hardware, weigh the costs of buying new hardware with using simple Wi-Fi technologies.

Both computers will need a networking interface. Any computer sold within the last five years will more than likely have an Ethernet hookup. Then all you need is an Ethernet cable. An Ethernet cable will provide much higher connection speeds than wireless alternatives and both Windows and Mac OSX make configuration very easy with networking wizards and guides.

If your computer lacks an Ethernet interface, you can buy special USB enabled Ethernet devices that are standard plug and play.

If you want to share your internet connection between computers, you will want to get a router, or hub. Buy a multiport hub so you can add other devices later — a printer, scanner, or server. Even if you don't plan on sharing information between the computers, you can always configure your network later to accomplish the task.

With a little trial and error, you should have little trouble setting up your first network. And you will quickly realize the value and convenience or your network.
