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.

Explain different types of storage devices

Topic: Explain different types of storage devices in Computer systems Storage Devices Storage devices are used to store data and instructions permanently. Storage devices are also called secondary storage devices / backing storage devices / external storage devices or auxiliary storage devices. Examples of storage devices include Hard Disk, CD and DVD etc. Why Secondary Storage Devices are Used? Secondary storage devices are used because: Primary memory(RAM) is volatile and temporary. When computer is switched off, all data in ram is erased. Storage devices can store large amounts of data and instructions permanently whereas Primary memory has less capacity of storing data. Types Of Storage Devices There are three main types of storage devices:  Magnetic Tape   Magnetic Disk   Optical Disk   Flash Memory storage devices 1. Magnetic Tape Magnetic tape is the oldest storage device. It is made of plastic coated with m...

Explain Different Types Of Output Devices

Output devices Out put devices are used to display results of processing to the user. They perform the following functions:  Receive results from memory  Convert data into human readable form  Display results to the user Examples include: Monitor, printer, plotter, speaker, and multimedia projector. Different Types of Output Devices 1.    Monitor LCD Monitor CTR Monitor     Monitor is the most commonly used output device used to display results of processing. It has a TV like shape. Pictures on monitor are formed with picture elements called PIXEL. Monitors may be Monochrome that will display results in Black & White. Color Monitors are also available. They display results in multi colors. Monitor produces soft copy output. 2.    Printers Printers are used to produce hard copy out put. They print processing results on paper. Printers are divided into two main categories: · ...

Types Of Scanners Input Device

Scanner / Optical Scanner A scanner is an input device for computer. It can scan any printed document with text as well as images. It will : Read any printed paper or picture, Convert text or images into digital form Saves this converted digital file into computer storage for later use Uses Of Optical Scanners You can scan your documents or pictures to: Store into computer memory. To save lot of effort and time because if you type the whole text on printed page, it will take effort as well as time). Show image or text on computer screen or on a multimedia projector's screen. In addition, you can send this scanned document or image to your friends all over the world with the help of Internet & Email. You can publish the scanned documents or images on your website or blog. You can apply online and send the scanned images of your academic documents in any part of the world within minutes. If your scanner supports OCR - Optical Character Recognition, you can scan a page...
