Types of Computer Network

Computer Network is a collection of autonomous computers interconnected by a single technology.

Classification of Computer Network:

Computer Network can be classified mainly into three categories –
1. Local Area Network (LAN)
2. Metropolitan Area Network (MAN)
3. Wide Area Network (WAN)

Local Area Network (LAN):

LANs are privately owned networks laid within a single building or a campus up to a few kilometres in size. It can be distinguished from other kinds of networks by three characteristics: size, transmission technology, and topology.
Example: Ethernet
Computer Network

Metropolitan Area Network (MAN):

MAN is a network that is spread over cities or over metropolitan areas. It may be partially or completely privately or publicly owned.
Example: Cable TV network.
MAN

Wide Area Network (WAN):

WAN spans over a large geographical area, often a country or a continent. In most of the WANs, the subnet consists of transmission lines which carry the bits and switching elements which are special kind of computers that are called Router which is connected with a number of transmission lines.
Example: Internet
