Depending on the size and coverage area of the network, it can be classified into the following:-
1. Local Area Network (LAN)
LAN is a computer network that spans a relatively small area. Most LANs are confined to a
single building or group of buildings area such as office building, manufacturing plant,
educational institutions etc. Hence most LANs connect workstations and personal
computers. Each computer in a LAN has its own CPU with which it executes programs, but
it is also able to access data and devices anywhere on the LAN. This means many users can
share expensive devices, such as laser printers, as well as data. Users can also use the LAN
to communicate with each other, by sending e-mail or engaging in chat sessions.
LANs are capable of transmitting data at very fast rates, much faster than what can be
transmitted over a telephone line, but the distances are limited, and there is also a limit on
the number of computers that can be attached to a single LAN.
