The features of LAN include the following
a) Limited geographical area say within a few kilometers.
b) Common communication link for sharing information, software and peripheral devices
without regard to proximity of user to such resources on the network.
c) High transmission capability.
d) Low error rate as the network contains built-in component for detecting for system errors.
e) Private ownership by the user.
f) Not subject to regulation by the telecom service.
LAN interconnects computers and computers and components within a limited
geographical area. Such LANs are normally set up within a single site can have one or more
business complex, a hospital, an office- building etc. The site can have one or more buildings but
they should not be too for a way, say less then5 kilometers. A LAN can also include a variety of
computer systems and devices such as workstations, microcomputer, file servers, plotters,
scanners, graphic terminals and printers.
A large personal computer or mini computer serves as the LAN’s hub. A high capacity
hand disk is attached to the hub as data files and software are stored on the network file server.
The users can load the software on the file server and retrieve data files for processing. The
output can be directed to the printer attached to the LAN.
Any the communication network that meets most or all of the following characteristics
can be classified as LAN:
a) All the devices on the network share a common transmission medium, that is, the cable and/
or the controller.
b) The devices connected to the network can operate independent of the network.
c) Any device connected to it can communicate with any other device on the network, and
d) The network is capable of supporting heavy data traffic over short distances compared to
telecommunication network.
e) The network covers a limited area usually a few kilometers in radius or a single site like a
university campus, an office or a factory.
