LAN: LAN is a Local Area Network. As name suggests LANs are basically used to connect a limited geographical area: for e.g. when we want to use network at home, a school, an office, at college, etc. Computers placed in this limited area are linked together. LANs can span over a limited range i.e. of 1 km in radius.Communication is carried out from one computer to another, and there is no need of any central computer, and each computer has the same role. The smallest LAN can consist of 2 computers.omputers placed in this limited area are linked together. LANs can span over a limited range i.e. of 1 km in radius.
