LAN is pronounced "lan", and stands for local Area Network. In a typical LAN, there is a

central network server which supports a number of terminals. Users have to

log onto the network server. Pages of information that can be viewed within a LAN are called

an intranet. A number of LANs connected to each other via satellite or other form

of communication are called a WAN (Wide Area Network). To be used as network terminals, each computer needs to have a network card installed.
