What is a network?

A network is a group of linked computers, printers, scanners, etc. They are connected by either cables (wired "Ethernet") or radio waves (wireless "Wi-Fi").

Networking lets you share one broadband internet connection in your home or small office. You can also share files, printers, scanners, and other devices. Multiple users can do all of the following simultaneously:

  • Check email
  • Bank or shop online
  • Play internet games
  • Download music
  • Instant message
  • Much much more

If you choose a wireless network, you can do all of the above without wires!
