Overview

Computer network helps computers to communicate with each other.Computer network is classified into three category. They are Local Area Network (LAN), Metropolitan Area Network (MAN), Wide Area Network (WAN). This note elaborates about different types of computer networks.
Computer Network Categories

Computer network is classified into three category. They are as follows:

  • Local Area Network (LAN)

    A local area network (LAN) is small network of computer. It is a network of computers within small area like room, building, or colleges. Nowadays instead of cables, wireless media are used as data transmission channel. LAN where wireless media are used is known as Wireless Local Area Network.

  • Metropolitan Area Network (MAN)

    It is larger network than LAN.Metropolitan Area Network (MAN) is a network of computer within a city or between neighboring cities. Big companies like banks, offices etc use MAN. In MAN, cables and unbounded communication media are used as the transmission channels.

  • Wide Area Network (WAN)

    A wide area network (WAN) is a very large network of computers. WAN is a network of a computer in a wide geographical areas such as country, neighboring countries, continent etc. A WAN can be formed by joining many LANs and WANs. The Internet and Intranet are the WANs.

Things to remember
  • Computer network is classified into three category. They are Local Area Network (LAN), Metropolitan Area Network (MAN), Wide Area Network (WAN).
  • A local area network (LAN) is small network of computer. It is a network of computers within small area like room, building, or colleges.
  • Metropolitan Area Network (MAN) is a network of computer within a city or between neighboring cities.
  • It includes every relationship which established among the people.
  • There can be more than one community in a society. Community smaller than society.
  • It is a network of social relationships which cannot see or touched.
  • common interests and common objectives are not necessary for society.

A local area network (LAN) is a small network of computers that are relatively near with each other within a small area like a room, building or within a short distance through wire or wireless media. A LAN where wireless media are used is known as Wireless Local Area Network (WLAN).

A metropolitan area network (MAN) is the network of computers spread over a city through wire or wireless media. A MAN can be formed by joining two or many groups of LANs within a cities. Network of different branches of bank, college, companies etc. within a same city are examples of MAN

A wide area network (WAN) is the large network of computers in wide geographical area such as cities, districts and countries through satellite or other long range communication technologies. A WAN can formed by joining many groups of LANs and MANs. The internet and intranet are the examples of WAN
