c)      WAN (Wide Area Network)

2.      LAN (Local Area Network)

A LAN is a type of network which covers small area i.e. within a room, building, or short distance by using cables or small wireless devices. It is controlled by a single organization. It uses private connection media. E.g.: network in a school, college or cyber cafe. The diameter is not more than a few kilometres. LAN offers bandwidth of 10-100 Mbps.

3.      MAN (Metropolitan Area Network)

A MAN is a type of network which covers an entire city. It is controlled by single or group of organization. It uses private or public connection media. E.g.: interconnection between different branches on same branch and ISP providing internet services. It offers a number of network services compatible with bandwidth from 128 kbps to 1 Gbps.

4.      WAN (Wide Area Network)

A WAN is a type of network which  connects two or more computers generally across a wide geographical area such as cities, districts, and countries. It is controlled by group of organization. It uses public connections media like telephone lines, satellite links or microwave system to connect several LANs and MANs.  E.g. internet. Data transmission in WAN is slower than LANs and WANs
