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

Different types of networks - what is LAN-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.

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 other facilities in the

Important Objective Type Questions 101-155

MMC stands for multimedia card. SD stands for secure digital card. System Bus  is used to connect main components of a computer such as cpu and main memory. A Port is an interface or a point of attachments. POS stands for Point Of Sale terminal. ATM stands for Automated Teller Machine. PIN stands for Personal identification number. Kbps stands for kilobits per second. Mbps stands for megabits per second. A port that transmits one bit at a time is called Serial Port. A type of port that transmits many bits at a time is called Parallel Port. LPT stands for Line Printer. Examples of system software are Operating System, Utility Programs and Device Drivers. Examples of operating systems are DOS, Windows, Unix and Linux. Examples of Utility programs are File Manager, Image Viewer, Disk Scanner and File Compressor. Software used to detect and remove viruses is called Antivirus . Examples of antivirus programs are Mcaffee, Avast,

Advantages and Disadvantages of Ring Network Topology

Topic: Advantages and Disadvantages of Ring Network Topology alongwith detailed working of Ring topology What Do You Mean by Ring Topology? In Ring topology, each computer is connected to the next computer such that last computer is connected to the first. Every computer is connected to next computer in the ring. Each computer retransmits what it receives from the previous computer. Suppose, computer A needs to send data to computer D. Now the computer A sends data to computer B. As computer B is not the destination computer, so it will retransmit data to computer C. Finally, Computer C will transfer data to computer D, the destination computer. When a node sends a message, the message is processed by each computer in the ring. If a computer is not the destination node, it will pass the message to the next node, until the message arrives at its destination. Advantages of Ring Network Topology 1. It is relatively less expensive than a star topology network. 2. In a Rin
