When two or more computers are connected in a room or building this is called a local area network (LAN). A wide area network (WAN) covers a large geographical area such as a country or continent.

There are two types of network:

LAN – Local Area Network

WAN – Wide Area Network

Local Area Network (LAN)

A local area network (LAN) has several benefits such as:

– You can share peripherals like expensive laser printers and eFax machines

– A fileserver can be used to store and share documents and files centrally

– Email can be sent between computers

– Computers on the network can be centrally managed

Wide Area Network (WAN)

This could be a network of school computers across a city or a business that has computers in offices all over Scotland. A wide area network (WAN) has similar advantages to a LAN. The major advantage is that it has a much wider geographical coverage for accessing files and sending emails.
