share data with other users using
network-connected peripheral devices, or access it remotely even if you keep it
on other connected devices.

·        
You can also share
a single internet connection as it helps reduce costs and can help protect your
computer systems if you secure the network properly.

·        
It also helps save
storage capacity if multimedia, such as images and music, are stored on other

There are several types
of computer networks. Computer networks are characterized by their purpose and
size. Some of them are:

·        
LAN (Local Area
Network)

·        
WAN (Wide Area
Network)

·        
MAN (Metropolitan
Area Network)

·        
PAN (Personal Area
Network)

A LAN can be as small as
two computers interconnected with each other by a single cable to share a
broadband or an ADSL connection but now LAN devices can be used over great
distances as it can span many sites within a town or city.
