4. Types of Computer Networks Sir Enimil Anti-Dote Series

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. Sir Enimil Anti-Dote Series Source: https://www.javatpoint.com/types-of-computer-network

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. Sir Enimil Anti-Dote Series

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. Sir Enimil Local Area Network – source: TechTerms.com

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. Sir Enimil Anti-Dote Series

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. Sir Enimil

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. Sir Enimil Anti-Dote Series

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. Sir Enimil Anti-Dote Series
