This document provides an overview of computer networking. It defines networking as interconnecting two or more computers to enable communication and sharing of resources. It discusses the applications of networking like sharing printers, software, and data. The advantages include increased speed, reduced costs, and improved security. Disadvantages are high installation costs and failure risks. The document classifies networks by geography into personal area networks, local area networks, wide area networks, metropolitan area networks, and campus area networks. It provides examples of each type of network.

INTRODUCTION

3. What is Networking
A Computer network is defined as the
interconnection of two or more computers.
It is done to enable the computers to
communicate and share available resources.

4. Applications of Networking
Sharing of resources such as printers
Sharing of expensive software’s and Database
Communication from one computer to another computer
Exchange of data and information among users via network
Sharing of information among users via network
Sharing of information and geographically wide areas

5. Advantages of Computer Network
Increased speed
Reduced Cost
Improved Security
Centralized Software Managements
Electronic Mail
Flexible Access

6. Diadvantages of Computer Network
High cost of Installation
Requires Time For Administration
Failure of Server
Cable faults

7. Classification of Area by their
Geography

8. Personal Area Network (PAN)
A personal area network is a computer network organized
around an individual person
It Generally consisits of a mobile, computer,a cell phone
or personal digit assistant. PAN enables the communication
among these devices
It can also be used for comunication among personal
devices themselves for connecting to a digital level
network and internet
The PAN’s can be constructed using wireless or cables

10. Local Area Network (LAN)
LAN is a network which is designed to operate over a small
physical area such as an office, factory or a
group of buildings
LAN’S are easy to design and troubleshoot.
Exchange of information and sharing of resources
becomes easy because of LAN
In LAN all machines are connected to a single cable
Different types of topologies such as star,tree, bus, ring etc
Can be used

11. LOCALAREA NETWORK (LAN)

12. Wide Area Network (WAN)
When network spans over a large distance or when the
computers to be connected to each other are at widely
seperated locations a local area network cannot be used a
wide area network (WAN) is installed
The communication between different users of WAN is
established using leased telephone lines,satellite,
links and similar channels
It is cheaper and more efficient to use the phone
network for the link

13. Wide Area Network(WAN)

14. Metropolitian Area Network (MAN)
It is in betweeen LAN & WAN technology that covers the
entire city
It uses similar technology as LAN
It can be a single network such as cable tv network,or a
measuere of connecting a number of LAN’s or a large
network so that resources can be shared LAN to LAN as
well as device to device

15. Campus Area Network (CAN)
A campus area network is madeup of an interconnection of
LAN with limited geographical area.
Network equipments such as switches, routers and the
transmission media I’e optical fibre etc are almost entierly
owned by the campus owner
