Computer Network : LAN, MAN, WAN.

Hello Friends,

In this blog post, I am going to let you know about the basics of computer networks.

Before I explain about the network, I just want to let you aware of the network first.

What is the network?

A network is a medium(medium can be anything like road, bridge) which connects two or more objects. And an object can be anything in this universe which has a physical existence.

For example, Network of a specific group of peoples, networks of trails, a network of a river, a network of mobile, human network and etc.

What is computer networks?

A network that connects two more computer with a medium(wire or wireless) is called computer network.

You can actually connect two computer devices either with a wire or without wire.

If it is connected with wires then it is considered as wired or if is connected without wires just with wifi routers or modems

then it is considered as wireless networks.

What is the different type of networks?

The networks are divided on the basis of the distance and range.

The network is mainly divided into three categories.



it stands for local area network, this network is built within the office or home.

It is designed in a small area, it is generally established in a range of 0-1 km.

Lan can be of both types wired LAN or wireless LAN.


LAN can build with the help of switches, bridges, wires, routers or modems.

So you would have seen in your office and college the computer systems are usually connected with LAN cable or wifi routers.

In this cable LAN system, we can connect several computers with the ethernet cable and can transfer the data across the computers without the internet.

But when the computer or laptop are connected with the wireless(specific radio signal) or connected with some common internet access point through wifi.


it stands for metropolitan area.

It is also called large LAN, it is designed for a bigger area than a LAN.

It is spread in a range of 1-50km, it can cover almost a city.

To design a MAN network, necessary equipment needed are a wire(twisted pair, optical fiber), switches, bridges, routers, the internet.

This networks connects the several building and offices of the city and make them one network.


it stands for wide area network, and it ranges from 1000 to 10,000km and it can cover whole continent or planet.

It connects the networks of two cities, countries, continents and etc.

This network is designed with the help of routers only for communicating through different networks.


What is the difference between LAN, MAN, WAN……?
