2. 1.0 INTRODUCTION
The purpose of a computer communications network is to allow moving information from one
point toanother inside the network. The information could be stored on a device, such as a
personal computer in the network, it could be generated live outside the network, such as speech,
or could be generated by a process on another piece of information, such as automatic sales
transactions at the end of a business day. The device does not necessarily have to be a computer;
it could be a hard disk, a cameraor even a printer on the network. Due to a large variety of
information to be moved, and due to the factthat each type of information has its own
conditions for intelligibility, the computer network hasevolved into a highly complex system.
Specialized knowledge from many areas of science andengineering goes into the design of
networks. It is practically impossible for a single area of science or engineering to be entirely
responsible for the design of all the components. Therefore, a study of computer networks
branches into manyareas as we go up from fundamentals to the advanced levels.
2.0 MOBILE COMPUTING
2.1DEFINITIONUsing a computing device while in transit. Mobile computing implies wireless
transmission, butwireless transmission does not necessarily imply mobile computing. Fixed
wireless applications usesatellites, radio systems and lasers to transmit between permanent
objects such as buildings andtowers

4. 3.0INTERNET TECHNOLOGY ANDSERVICES
3.1 VoIP
Voice over Internet Protocol
Example of VoIP adapter setup in residential network
is ageneral term for afamily oftransmission technologies for delivery of voice communications over
IP (internet protocol) networks such as the Internet or other packet-switched networks.
Other terms frequently encountered andsynonymous with VoIPare IPtelephony,Internet telephony,
voice over broadband(VoBB), broadband telephony, and broadband phone.
3.2BLOG
A blog is basically atype of website,like a forum orasocial bookmarkingsite. As such it is defined by
thetechnical aspects and features around it,and not bythe content published insideit.

5. 4.0 TYPES OFNETWORK
4.1 PAN
A personal area network (PAN) is acomputer network used for communication among
computer devices (including telephones and personal digital assistants) close to one's person. The
devices may ormay not belong to the person in question. Thereach of a PAN is typically a fewmeters.
PANscanbe used for communication among the personaldevices themselves
(intrapersonalcommunication), or for connecting to ahigher level network and the
Internet.Personal area networks may bewiredwith computer buses such as USBandFireWire.
4.2VPN
A virtual private network (VPN) is anetwork that uses a publictelecommunication infrastructure,
suchas the Internet, to provide remote officesor individual users with secure access totheir
organization's network. A virtual private network can be contrasted withan expensive system of
owned orleasedlines that canonly beused byoneorganization. The goal of a VPN is
to provide the organization with the samecapabilities, but at a much lower cost.

6. 4.3 WLAN
A wireless LAN (WLAN) is awirelesslocal area network that links two or morecomputers ordevices
using spread-spectrum or OFDMmodulation technology based to enable communication
betweendevices in a limited area. This gives usersthe mobility to move around within a
broadcoverage area and still beconnected tothenetwork

7. 4.4WIMAX
WiMAX, meaningWorldwide Interoperabilityfor Microwave Access, is
atelecommunicationstechnology that provideswireless transmission of datausing a variety
of transmission modes, from point-to-multipoint links to portable and fully mobileinternet access.
Thetechnology provides up to 3Mbit/s broadband speedwithout the need for cables.The technology is based
onthe IEEE 802.16 standard (also called Broadband Wireless Access). The name "WiMAX"was
created by the WiMAX Forum, which was formed in June 2001 to promote conformityand
interoperability of the standard. The forum describes WiMAX as "a standards-basedtechnology
enabling the delivery of last mile wireless broadband access as an alternative tocable and DSL"
5.0 CONCLUSIONWe can conclude that computer networks and communication makes our life
easier tocommunicate with each other and the world using the computer .
