What would we do without computer networks and the internet? Criminals would have to go back to robbing banks and students would fight for the one library book on a course topic!

A computer network is a group of computers and other hardware linked together to enable communication and to share resources among a wide range of users with different needs. 

The key benefit of networks is the sharing of resources whether it is a document on the internet or harwdware. Without a network, a classsroom of 30 computers would need a technician to install all software one by one. A printer will have to be plugged in and out of every computer as it is needed. To share data would mean sharing around flash storage for example.

If they are linked together in a small geographical area like a school, the network is called a Local Area Network (LAN). If they are linked over a wider geographical area as in two cities then the network is a Wide Area Network (WAN).

Other types include a global network(GAN), wireless networks (WLAN) as well as Peer to Peer (P2P) and one you will use a lot with your smart phone, wireless personal area networks(WPAN).
