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.

Bus Topology Advantages Disadvantages

Bus Topology Bus topology is the simplest network topology . In bus topology , all computers in network are connected to a common communication wire. This wire is called BUS. Terminators are used at both ends of wire. Bus Topology is Cheap, easy to handle and implement. Bus Topology require less cable. Bus Topology is best suited for small networks. Working of Bus Topology with Advantages and Disadvantages Advantages of Bus Network Topology 1. It is very simple topology . 2. It is easy to use. 3. It needs small amount of wire for connecting computers. 4. It is less expensive due to small wire needed. 5. If one computer fails, it does not disturb the other computers in network. Other computers will continue to share information and other resources with other connected computers. Disadvantages of Bus Network Topology 1. Only small number of computers can be connected in a bus network . 2. Network speed slows down as the number of computer increases in b...

Types Of Headings In HTML

HTML Hedings Headings in HTML are used to display Titles, Sub-Titles of Sub-Sub-Titles for your web page text. There are six types of headings in HTML. H1 is the largest heading and H6 is the smallest heading. <H1> is opening tag whereas </H1> is the closing tag for the largest heading. The text between <h1> and </h1> will be displayed as the main Title in your web page. Following are the six tags used for six types of headings in HTML. <H1> ... </H1> <H2> ... </H2> <H3> ... </H3> <H4> ... </H4> <H5> ... </H5> <H6> ... </H6> The H1 heading is used for main titles. Actually H1 heading will show the text in largest font size. H2 headings is used for Sub-Titles. H2 displays text in smaller font size than H1, H3 displays text of font size smaller than H1 and H2, and so on. H1 is for largest heading in a text page and H6 is for smallest heading.   Importance Of Headings in SEO H...

Explain Advantages Of Networks

Define Network with examples. Give importance of Computer Network. COMPUTER NETWORK We can define a Computer Network as a set of two or more connected computers to share information and other resources (data, files, printers, hard disk, modem, CD-Rom Drive, CD-Writer, DVD-Rom Drive, DVD-Writer etc.). The computers in a network can share: Data, Information, Files Software Hardware (printers, disk, modems)etc. Advantages of Computer Networks EXAMPLES OF COMPUTER NETWORK Computer network can be used in an office. Different people in the office can share common information and printer. Net Cafes use Computer Network for internet sharing. Net Cafe Owners can save money by sharing one DSL Routers / Modem and a single Internet Connection. Computer Network is used in Computer Laboratories of Schools, Colleges and other educational institutes. Internet, is also an example of a computer network. Internet is a network of millions of computers connected through phone lin...
