The term “computer network” refers to a collection of computers connected to one another that allows the computer to connect with another computer and share resources including data, applications, and other information.
Computer networks can be classified by the size. Computer networks are generally comprised of four kinds:
- LAN(Local Area Network)
- PAN(Personal Area Network)
- MAN(Metropolitan Area Network)
- WAN(Wide Area Network)
LAN(Local Area Network)
- Local Area Network is a collection of computers that are connected to one another in the smallest space, such as office, building.
- The term “LAN” is used to connect to two computers via the use of a communication channel like coaxial cable, twisted pair or coaxial cable.
- It’s also less expensive since it is built using inexpensive hardware, such as routers and hubs and Ethernet cables.
- The data transfer is done at an more speed through the Local Area Network.
- Local Area Network provides higher security.

PAN(Personal Area Network)
- Personal Area Network is a network set up by one person, typically within a distance that is 10 metres.
- Personal Area Network is used to connect the computers for personal use. It is referred to by the name of Personal Area Network.
- Thomas Zimmerman was the first researcher to develop the concept that”the” Personal Area Network.
- Personal Area Network covers an area of 30 feet.
- Personal computers that are used to build the personal area networks are those of the mobile phone, laptop,, and play stations.
There are two kinds of Personal Area Network:
- Wired Personal Area Network
- Wireless Personal Area Network
Wireless Personal Area Network: Wireless Personal Area Network is built by utilizing wireless technology like WiFi, Bluetooth. It is a low-range network.
Wired Personal Area Network: Wired Personal Area Network is made by the USB.
MAN(Metropolitan Area Network)
- Metropolitan area networks are a system that extends over a greater geographical area, by connecting different LAN in order to create the larger network.
- Government agencies utilize MAN to connect with the public and private sectors.
- In MAN, a variety of LANs are linked to each via an exchange line for telephones.
- The most popular protocols used in MAN can be described as RS-232, Frame Relay, ATM, ISDN, OC-3, ADSL, etc.
- It has a wider area of coverage than the it has a greater range than Network(LAN).
WAN(Wide Area Network)
- Wide Area Network: A Wide Area Network is a network that covers an area of vast geographical size, like countries or states.
- An Wide Area Network is quite larger in comparison to the LAN.
- The term “wide area network” refers to the fact that a Wide Area Network is not only restricted to a single area It covers an entire geographical area using the telephone line, fiber optic cable, satellite links or.
- The internet is among the most powerful WANs in world.
- An Wide Area Network is widely employed in government, business as well as education.
