Computer Network and its types

MAIN TYPES OF COMPUTER NETWORK

As far a computer networks are concerned, we can identify three main types. They are,

 Local Area Networks (LAN)

A computer network, which is spread in a small area, is called a Local Area Network. In most of the instances, this kind of network is limited to one building or else the network is built connecting a few places, which are situated very close to each other. For instance, a computer network built in a school or a university can be called a Local Area Network.

 Metropolitan Area Networks (MAN)

Networks, which are spread in a larger area than a Local Area Network but smaller than Wide Area Network, are called Metropolitan Area Networks. A computer network, which is maintained in a government institute, can be cited as an example here. The relevant divisional institutes are operated while being connected to this network. For instance, a computer network, which connects Divisional Secretariats, can be called a Metropolitan Area Network.

Wide Area Networks (WAN)

A computer network, which is spread in a large area, is called a Wide Area Network. The best example, which can be given for this, is the Internet. No geographical restriction can be shown is such a network.
