What is a Network?

A computer network is a collection of computers and other peripheral devices that are connected in order to exchange data and hardware resources. Computer networks aid in sharing of information, sharing of resources, storage efficiency, and timely communication, among other things.

Type of Networking

The size of a computer network defines its classification. A network can be tiny, containing only one system, or as large as needed. The following are the various types of computer networks:

  • PAN

  • LAN

  • MAN

  • WAN

 

Type of networks

 

PAN (Personal Area Network)

  • It is the smallest network of computers.

  • Bluetooth or other infrared-enabled devices could be used to connect devices.

  • It has a 10-metre range of connectivity.

  • It can cover up to 30 feet in diameter.

  • PAN network enables a single person's personal devices to connect with each other.

Types of PAN (Personal Area Network)

Personal Area Network is divided into two categories. 


Types of Personal Area Network


  • Wired Personal Area Network: The USB is used to create a wired Personal Area Network.


USB


  • Wireless Personal Area Network: Wireless Personal Area Networks (WPANs) are the connection networks created by combining wireless technologies like WiFi and Bluetooth. It is a network with a short range.


Wi-Fi and Bluetooth connection network


LAN (Local Area Network)

  • In a small network, such as a building or a small office, systems are connected.

  • LAN network is low cost.

  • Token-ring technology is being used.


Token Ring is a computer networking method that is used to build local area networks. Children are having fun and forming a ring in the image below; similarly, computers in the token ring network are connected in a ring shape.


Ring Topology



  • Two or more personal computers can be connected with nodes (wires or cables).

  • Data transfer is quick and well-rated.


LAN Network


MAN (Metropolitan Area Network)

  • Cable TV Connection is an example of a network that can be connected within a city.

  • Ethernet, ATM, Token-ring, and FDDI are some examples.

  • MAN network has a wider range of applications.

  • This network interface could be used to connect citizens to various organisations.


Man Network


WAN (Wide Area Network)

  • A network that spans a country or a larger group of individuals.

  • The WAN network connects telephonic connections as well.

  • The internet is the world's largest WAN, and it is mostly utilised by government entities to handle data and information.

  • The internet would weigh about 2 ounces (50 grams). How does one calculate the internet's weight? Russel Seitz, a physicist, estimated the weight of billions of electrons that make up the data we actually send and forth every day.

Summary

In this article, we have discussed the concept of a network and its different types. First, we discussed the definition of a network, and then the characteristics of its different types. We have learnt the differences between various types of networks.

FAQs on Different Types of Networks

1. What is a network?

A computer network is a collection of computers and other peripheral devices that are connected in order to exchange data and hardware resources.

2. Write 3 differences between Local Area Network and Wide Area Network.

Local Area Network(LAN)

Wide Area Network(WAN)

The data transfer rate on a LAN is higher.

When compared to LAN, WAN has a lower data transfer rate.

The LAN is owned privately.

Private or public ownership of a WAN is available.

The LAN has a high speed.

The WAN is slower than the LAN.

3. List any 4 advantages of MAN.

Advantages of MAN network are as follows:

  • When compared to WAN, it provides better security.

  • In comparison to WAN, MAN requires fewer resources.

  • Implementation costs are cheaper.

  • Increases the rate at which data is sent.
