What is networking?

Network: A network is a group of two or more computers or other electronic devices. They are interconnected for the purpose of exchanging the data and sharing the resources either by a cable or a wireless connection.

     Today’s networks tend to be a bit more complex and don’t just consist of two computers. A system with more than 10 participants usually use client-server networks. In these computers, one will act as a server and the remaining will act as a client. In these networks, a central computer (server) provides resources to the participants in the network (clients).

Types of the network:

1.     Peer-to-peer network: The simplest network is a combination of two computers connected by a wire.

2.     Client-server network: It is the medium through which clients access resources and services from the main computer (server) via either Local Area Network (LAN) or Wide Area Network (WAN).

How does a network work?

    In a client-server network, there is a central device called a server. The server is connected to the remaining devices, which are called clients. This connection is wired or wireless.

Networks are divided based on the range of area.

  Networks are classified in 4 categories:

Personal Area Network (PAN): PAN is used for interconnecting the devices within a room. Example Wi-Fi.

Local Area Network (LAN): LAN is used for interconnecting the devices within a building or a company.

Metropolitan Area Network (MAN): This network is used to connect within a city.

Wide Area Network (WAN): This network is used in the range of nationwide.

Global Area Network (GAN): This Network range is worldwide. Like as internet. So, if you are connected to the internet, simultaneously it will act as a WAN or GAN.
