3. LESSON OBJECTIVES
At the end of this lesson, the student should be able to:
Explain the types of networks.
Understand the features of the types of networks.

4. Types of Computer Networks

5. Personal area network
A personal area network, or PAN, is a computer network
centred on a single person within a single building.This
could take place inside a small office or home.

6. Features of personal area network
Communication is short range
It does not consume much power
It is very less in cost and has no complex connectivity
It includes devices like laptops, smartphones, printers, etc.
It supports both wired and wireless connection.

7. Local area network
A local area network is a network that connects computer
systems and devices in a small area, such as an office,
home, or several floors of a building (LAN). Personal
computers, laptop computers, and powerful mainframe
computers can all be linked together using LANs.

8. Features of local area network
It has limited geographical area because it is used mostly at
places were devices are close to each other like an office
building.
Data error rate is very less since data is transferred to a
limited geographical area.
Delay in communication time is short, making it highly
reliable.
It is a private network. It is not controlled by any outside
regulatory body.

9. Metropolitan area network
Metropolitan area networks cover a larger area than that of a
local area network and smaller area as compared to wide area
network.These networks are mostly used as links between
office buildings that are located throughout a city.

10. Features of metropolitan area network
It covers a geographical area wider than local area network but
lesser than wide area network
It is an interconnection of local area networks
It is controlled or owned by a user group or an Internet service
provider (ISP) who sell services to users
There is moderate to high data rates
It helps in the sharing of resources across cities
Metropolitan area network provides uplinks for connecting
local area networks to wide area networks and the Internet.

11. wide area network
Wide area network is a network that extends over a large
geographical area, although it might be confined within the bounds
of a state or country.A wide area network is a collection of local area
networks or other networks that communicate with one another.

12. Features of wide area network
It generally covers large distances like states, countries and
continents
Communication media used are satellite, public telephone
networks, cable systems, etc.
Wide area network provides uplinks for connecting local
area networks and metropolitan area networks to the
Internet
It facilitates the sharing of resources globally.
