types of networking

There are mainly three types of networking based on their size

·         Local Area Network (LAN)

·         Metropolitan Area Network (MAN)

·         Wide area network (WAN)

LAN (Local Area Network)

A LAN is a computer network which spans over a small geographical area such as home, building, office, etc. In LAN, computers are placed relatively close. Since computers are located within small distance, they do not need special devices and cables to connect with each other.

MAN (Metropolitan area networks)

A MAN is a computer network which connects two or more LAN networks within same city. When due to distance connecting two LANs is not possible, MAN network is used. It is larger than LAN but smaller than WAN. It deploys special devices and cables to connect the LANs.

WAN (Wide Area Network)

WAN is a computer network which spans over a large geographical area such as state, region, country etc. WANs are typically used to connect two or more LANs or MANs which are located relatively very far from each other. To provide connectivity, this network uses special devices, cables and technologies.
