Q3. What are the four types of networks?

Ans. Four types of computer networks are LAN (Local Area Network), PAN (Personal Area Network), MAN (Metropolitan Area Network) and WAN (Wide Area Network).

LAN (Local Area Network)

A LAN is a group of computers connected in a small area such as building, office. IT is used to connect computers via a communication medium such as twisted pair, coaxial cable, etc. It is comparatively inexpensive as it is built with hardware such as hubs, network adapters, and ethernet cables. It provides higher security for other types of computer networks.

PAN (Personal Area Network)

A PAN is a network arranged within a person, typically within a range of 10 meters. It is used to connect personal devices over an area of 30 feet or less. These devices may include laptops, mobile phones, media players, and even play stations.

MAN (Metropolitan Area Network)

A MAN covers a larger geographic area by different interconnecting LANs to form a larger network. This type of computer network is mainly used by Government agencies to connect to its citizens and private industries. Some of the most used protocols in MAN are RS-232, Frame Relay, ATM, ISDN, OC-3, ADSL, etc.

WAN (Wide Area Network)

A WAN extends over a large geographical area such as states or countries, extending via telephone lines, fiber optic cables, or satellite links. An example of a WAN that is used around the world is the Internet.
