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.
