Networks - Local Area and Wide Area Networks


A network contained within one building or site is called a Local Area Network (LAN). Anetwork that spans several sites across a city, country or even the world is called a Wide Area Network (WAN).

A Client/Server network may be a LAN or WAN, however a peer-to-peer network can only be a LAN.

The most famous and widely used Wide Area Network is the Internet which contains many thousands of servers and many millions of clients right across the world.
