What is Computer Network LAN, WAN, MAN, SAN, CAN, PAN and GAN?

Greetings friends! Today we will talk about computer networking means a computer network LAN, WAN, MAN, SAN, CAN, whether PAN and GAN And how it works.  

What is a computer network?

A computer network consists of two or more computers that are connected with each other and share resources such as printers, servers and hardware, and sharing data in the form of files, facilitating electronic communication. . On the network the computer can be connected through twisted pair cable, telephone lines, radio waves, satellites or optical fiber cables.
United States of America Department of Defense 's first computer network 'Advanced Research Projects Agency Network (ARPANET )' was designed. Since then, the innumerable new designs of new computer networking technologies have come to our world.
In this tutorial, only the first three network technologies namely LAN (LAN), WLAN, WAN, MAN, MAN, SAN, SAN, PAN (PAN) and GAN Have been included.


Computer networks can be classified into different types depending on their scale of scale. they include:


The local area network (local-area network) is a computer network used in a relatively small area. Often, a LAN is restricted to a room, building or group of buildings.
However, a LAN can be connected to other LANs at any distance via telephone lines and radio waves. Local area networks (local-area networks) include a small physical area, such as a small group of houses, offices, or buildings, such as schools or airports.


Wireless local area network (wireless local area network) is a wireless computer network that connects two or more devices using wireless communications within a limited area such as home, school, computer lab or office building.
There is a wide-area network ofcomputer networks which are used in relatively large geographical areas, usually having a radius of more than 1-KM. Generally, a van (WAN) consists of two or more local area networks (LANs).
Computers connected with wide-area networks are often connected through public networks, such as telephone systems. They can also be added through leased lines or satellites.

Man (MAN)

Metropolitan area network (metropolitan area network) is a computer network which is covered by a large local area network (LAN) with geographical area or computer, but the area covered by a wide area network (WAN) is small.

San (San)

The storage area network  is a high-speed network of storage devices that also connects the storage device to the server. It provides block-level storage that can be accessed by applications running on any network server.
Storage area networks help remote computer storage devices, such as disk arrays, tape libraries, and optical jukebox, connect to the server in such a way that they seem to be connected locally to the operating system.

Can (CAN)

The Controller Area Network is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without host computers.


The Personal Area Network is a computer network used for data transmission between devices like computers, telephones, tablets, personal digital assistants, fax machines and printers, which are located near a user.


The global area network is a network that is used to support mobile number of arbitrary number of wireless LAN (LAN), satellite coverage areas, etc.


Through the use of InternetWorking Gateway is the practice of connecting a computer network with other networks which provides a common way of routing information packets between networks. The resulting system of interconnected networks is called an internetwork, or simply called an internet.
Computer networks are an integral part of our lives. This is because of networking that telephone, television, radio and internet are working on our gestures.
