Computer networks may be classified on the basis of the geographical area in two broad categories.
1. Local Area Network (LAN):
- Networks used to interconnect computers in a single room, rooms within a building or buildings on one site are called LAN
- LAN links computers i.e. software and hardware, in the same area for the purpose of sharing information
- Usually, LAN links computers within a limited geographical area because they must be connected by a cable
2. Wide Area Network (WAN):
