1.0 INTRODUCTION
A computer network is a system of interconnected computers and peripherals
devices.For examples,it may connect computers,printers,scanners and cameras. Using
hardware and software, these interconnected computing devices can communicate with
each other through defined rules of data communications. In a network, computers can
exchange and share information and resources. A computers network may operate on
wired connections or wireless connections. When two or more networks are linked or
connected and are able to communicate with one another using suitable hardware and
software,it is called an internetwork.
Communications is about the transfer of information from a sender,across a distance,to
a receiver. Using electricity,radio waves or light, information and data in the form of
codes are transmitted trough a physical medium such a wire,cableor even the
atmosphere.
Therefore,
in
order
to
make
communication
possible
from
computers,across telephones and radios and back to computers and other digital devices
again,there must be a signal translator,which we call a modem. The modem, which is
short for modulator or demodulator,converts digital signals into analog and back again
into digital signals for information to move across the telephone line.
2.0 MOBILE COMPUTING
2.1 Definition
Mobile computing is human computer interaction by which a computer is
expected to be transported during normal usage. Mobile computing involves
mobile communication, mobile hardware and mobile software. Communicaton
issues include ad hoc and infrastructure networks as well as communication
properties, protocols, data formats and concrete technologies. Hardware includes
mobile devices or device components. Mobil software deals with the
characteristics and requirements of mobile applications.

3.0 INTERNET TECHNOLOGY AND SERVICES
Voip services convert your voice into a
digital signal that travels over the Internet.
If you are calling a regular phone number,
the signal is converted to a regular
telephone signal before it reaches the
destination. Voip can allow you to make a
call directly from a computer, a special
voip phone, or a traditional phone
connected to a special adapter. In addition,
wireless "hot spots" in locations such as
airports, parks, and cafes allow you to
connect to the Internet and may enable
you to use voip service wirelessly.

3.2 BLOG
A blog (a
truncation
expression weblog)
is
of
a
the
discussion
or
informational site published on the World
Wide Web consisting of discrete entries
("posts") typically displayed in reverse
chronological order (the most recent post
appears first). Until 2009, blogs were usually
the work of a single individual[citation
needed]
occasionally of a small group, and often
covered a single subject
4.0 TYPES OF NETWORK
4.1 PAN
A personal area network (PAN) is a
computer
network used
for
data
transmission amongst devices such as
computers, telephones, tablets and
personal digital assistants
4.2 VPN
4.2 VPN
A virtual private network (VPN) extends
a private networkacross a public network,
such as the Internet. It enables users to send
and receive data across shared or public
networks as if their computing devices were
directly connected to the private network,
and thus benefit from the functionality,
security and management policies of the
private network.[1] A VPN is created by
establishing
point connection
through
virtual point-tothe
use
of
dedicated
connections,
virtual tunnelling
protocols, or traffic encryption
4.3 WLA
4.3 WLAN
A wireless local area network (WLAN)
is a wireless computer network that links
two or more devices using a wireless
distribution
method(often spread-
spectrum or
OFDM radio)
within
a limited area such as a home, school,
computer laboratory, or office building.
This gives users the ability to move
around within a local coverage area and
still be connected to the network, and can
provide
connection
to
the
wider Internet. Most modern wlans are
based
on IEEE
802.11 standards,
marketed under the Wi-Fi brand name.
4.4 WIM4.4.4 WIMAX
Wimax (Worldwide
Interoperability for Microwave
Access)
is
family
ofwireless communications
standards initially designed to
provide 30 to 40 megabit-persecond data rates,[1] with the
2011 update providing up to
1 Gbit/s for fixed stations. The
8
name "wimax" was created by
the wimax
5.0 CONCLUSION
Computer networks have highly benefited various fields of educational sectors,business
world and many orgnizations. They can be seen every where they connect people all
over the world. There are some major advantages which compute networks has
provided making the human life more relaxed and easy.
