The advantages of networks are numerous they save money because only one printer, scanner or backup device is needed between multiple computers, files and memory can be shared between machines, files can also be made read only so they can’t be corrupted.

Software liecences are cheaper for networks than single computers and the administration is centralised so a program can be loaded onto multiple computers at once.

LAN (Local area network)

A group of computers under one administrative control

WAN (Wide area network)

A WAN connects LANs in different geographical areas, the internet is an example of this.

WLAN (Wireless LAN)

Wireless devices are used to connect computers

There are two main network types

Each user controls their own machine and decides what others can see and use eg printers
