What are different types of networks based on geographical spread ?

The different types of networks based on geographical spread are as follows :

1. LAN (Local Area Network) — Small computer networks that are confined to a localised area such as a building or­ factory, are known as Local Area Networks (LANs). LANs have geographical spread of upto 1 km.
2. WAN (Wide Area Network) — The networks spread across countries or on a very big geographical area are known as WANs. The WANs link computers to facilitate fast and efficient exchange of information at lesser costs and higher speeds. The largest WAN in existence is the Internet.
3. PAN (Personal Area Network) — It is the interconnection of information technology devices within the­ range of an individual person, typically within a range of 10 meters. PAN could also be interconnected without wires to the Internet or other networks.
4. MAN (Metropolitan Area Network) — MAN refers to a network that is spread over an area as big as a city.
