When multiple users share a single computer's resources and information through independent terminals, it is called computer networking. There are three types of computer networks: local area networks which operate within small physical areas like an office or factory; metropolitan area networks which interconnect multiple local area networks within a city or large campus; and wide area networks which can span entire countries or continents.

2. When a number of
users work together
with a single computer,
using their
independent terminals
to share resources and
independent terminals
to share resources and
information the system
is called networking.

3. Computer network may vary in size,
complexity, graphical spread. On basis of this
computer network is of three types:-
 Local Area Network (LAN)
 Metropolitan Area Network (MAN)
 Wide Area Network (WAN)

4. Lan is designed to operate over small physical
areas such as office, factory, its range may be 10
m (same room), 100m (same building), 1 km
(Same Company)

5. A metropolitan area network is a computer
network that usually spans a city or large
campus. A MAN usually interconnects a
number of local area networks (LANs) using a
high capacity backbone technology.

6. A wide area network (WAN) is a computer
network that covers a large geographic area
such as a city, country, or spans even
intercontinental distances
