There are five types of networks. Let's learn about them.

        LAN (Local Area Network)

        LAN is a short form of Local Area Network. It is a digital communication system that interconnects a
        large number of computers and other peripheral devices within a radius of less than 1 km. This type
        of network is usually preferred for a smaller area such as a residence, school, laboratory, university
        campus or office building. By using the LAN network, users can exchange data and messages in the
        easy and fast way. Cables and communication devices are used to connect computers to the LAN.

        MAN (Metropolitan Area Network)

        MAN consists of  two or more local area networks or campus area networks together that usually
        spans several buildings in the same city or town.

        WAN (Wide Area Network)

        WAN is a digital communication system that interconnects a large number of computers in a wide
        geographical area. This network may operate on a worldwide or nationwide basis. In such type of
        network, there may not be physical connection between computers. In WAN, telephone lines, microwave,
        satellite links, etc. can be used as transmission medium.
