Discussion of networking and its roles:
Networking has played a
huge role in effective global information communication something which allows and
connects users to access resources, hardware and services with other users regardless
of their location. The underlying principles of networking is of vital importance
as it has connected the world by the grouping of small networks through
internet links to support global communications. Network computing devices can
either be connected through cable media or wireless media but the best-known computer
network is the Internet.
Main benefits of computer networks include:
You can easily
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
machines or network-attached storage devices.
Networking computers also help to improve
communication, so that:
You can share
information and get in touch easily with staff, customers or friends and
Your business can
become more efficient – e.g. networked access to a common database can help
save time and prevent errors.
Staff can deal
with queries of customers and deliver a better standard of service as a result
of sharing customer data.
So what are the types of computer networks?
There are several types
of computer networks. Computer networks are characterized by their purpose and
size. Some of them are:
LAN (Local Area
WAN (Wide Area
PAN (Personal Area
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.
