Explain Different Types Of Computer Networks - LAN, MAN, WAN

Explain different types of computer networks:(LAN,WAN,MAN)

Today, we will discuss the main types of computer networks on the basis of the maximum distance covered where they can be accessed and operate. The main types of computer networks are:
LAN, WAN, MAN Explain different types of computer networks
LAN, WAN, MAN Explain different types of computer networks


1.    LAN - Local-Area Network
2.    WAN - Wide-Area Network
3.    MAN - Metropolitan-Area Network

1)LAN (Local Area Network)

What is LAN or Local Area Network

LAN stands for Local Area Network. It covers a small area. Most LANs are used to connect computers in a single building or group of near buildings. A network contained within a relatively small area, such as a classroom, school, or single building, is commonly referred to as a local area network.


Hundreds or thousands of computers may be connected through LAN. LANs are used in office buildings, college or university campus etc. Local Area Networks can transfer data at a very high speed. Data transmission speeds of LAN are 1 to 100 megabits per second.

Examples of Local Area Network

Following are examples of LAN:

  1. LAN is used in a computer lab to connect computers. The students can share software, files and data in the lab. They can send messages to each other with the help of Local area network.
  2. In Internet cafe, many computers can be connected through LAN -  local area network. These computers can share single connection of Internet. This saves a lot of money.
  3. Local Area Network can be used in an office to share common data and a network printer and any other software or hardware.
  4. A local area network in a digital library can provide access to centralized collection of digital books for many readers using different computers in library building.

2)WAN (Wide Area Network)

What is WAN or Wide Area Network?
WAN stands for wide area network. It covers a large area. A network covering a larger area than a single city is classified as a wide area network.WAN connects computers in different cities, countries and continents. So, Wide Area Networks are used to transfer data over very long distances across cities, countries or even in whole world. WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations.
Computers in WAN are often connected through leased lines telephone lines. They can also be connected through satellites. Transmission rate of WAN is 56 kbps to 45 Mbps. WAN is expensive than LAN. WAN is not as fast as LAN. There is a possibility of error in data transmission due to very long distance they cover. The largest WAN  is the Internet. With the help of internet, we can send our data in any part of the world.


Examples of WAN

In air line ticketing system, many offices of an air line company can be joined together using WAN. A person can get a ticket from any office in the country.
A bank with many branches in different cities can connect its branches through WAN. The customer can use his account from any branch.

3)MAN (Metropolitan-Area Network)

What is MAN or Metropolitan Area Network?
A metropolitan area network (MAN) is a network that covers an area of the size of a city. A network that spans the distance of a typical metropolitan area is sometimes referred to as a metropolitan area network. So, a MAN is larger than a local area network but it is smaller than a WAN. A MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities. MANs can use communications channels of moderate-to-high data transfer rates. It may use fiber Optic cable for fast speeds.
A MAN typically includes one or more LANs but cover a small area than WAN. A MAN often acts as a high-speed network.

Examples of MAN or Metropolitan Area Network:


  1. Mobile phones systems often use MAN to broadcast the mobile data in the form of radio waves.
  2. Many local ISPs manage MAN with the help of cable modems within a city.
  3. Local cable TV networks also uses MAN technologies to transfer mobile data through radio waves.

This is all about types of computer networks.

Introduction to Algorithms and Algorithmic Notation With Examples

Topic: Introduction to Algorithm and Algorithmic Notation With Examples What is an Algorithm? The step by step procedure to solve a particular problem is called an Algorithm .  A Good Programmer always writes algorithms before developing programs. Algorithmic Notation with example algorithms  Advantages of  writing an Algorithm The process of solving a problem becomes simpler and easier with the help of  algorithm. There are less chance of errors in the program, if we design algorithms before writing our programs in any programming language. We can convert an algorithm into a program of any programming language. It is not dependent on any programming language. Therefore it is easy to understand for anyone even without programming knowledge. What is the Relationship between an Algorithm and a Program Sponsored Links An algorithm is the sequenc of steps to perform a task, whereas a program is the set of statements to perfor...

Define Data and Information With Examples

DATA Data is the collection of raw facts and figures. Actually data is unprocessed, that is why data is called collection of raw facts and figures. Define Data and Information with Examples We collect data from different resources. After collection, data is entered into computer for processing. Data may be collection of words, numbers, pictures,  or sounds etc. Examples of Data 1) Student Data on Admission Forms When students get admission in a college. They fill admission form. This form  contains raw facts (data of student) like name, father’s name, address of student, obtained marks, photo graph etc. 2)    Data of Citizens During census, data of all citizens is collected. The staff will go house to house and collect data about citizens like number of persons living in a home, either they are literate or illiterate, number of children, data of each child, cast, religion, Computerized national Identity Card number, address, how many rooms and...

What are Dual Devices or Both Input/ Output Devices

The devices that can be used to perform both functions -input and output- are called Dual Devices. These devices are also called Dual Purpose Devices or Both Input/Output Devices. With the help of a dual purpose device, we can enter data into computer as well as we can output data from the computer to outside world.  For example, Dual devices include:  Touch Screen Monitor, Modem, Network Interface Card, Sound card, Hard disk drive, Floppy disk Drive, Magnetic Tape Drive CD-Writer and DVD-Writer etc. These are also called Input/output devices, because they perform both functions. Touch Screen Monitor Dual Devices or Both Input / Output Devices - Touch screens Touch Screen Monitor is an input/output device. It uses a special touch sensitive screen. The User can enter data by touching icons or menus on the screen. As soon as the user selects a command from menu, output is displayed on screen. Commonly touch screen monitors use sensors to detect touch of finger. ...
