Types of Computer Network
Computer Network is a collection of autonomous computers interconnected by a single technology. Computer Network can be classified mainly into three categories –
1. 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.
2. 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.
3. 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.
