What is Networking?

Two or more devices are connected through networking so that data and information can be shared between them. The router is used to connect to the network. Switches to build the network, Firewall to protect the network, IP Phones to make calls to the network and VPNs are needed to create a secure tunnel in the network.
Networking refers to the total process of creating and using a computer network in relation to hardware, protocols, and software, including Wired and Wireless technology. This includes the application of principles from various technical fields, such as IT, Computer science and Computer Electrical engineering. A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource to share today is an Internet connection. Other shared resources may include a printer or file server. The Internet can be considered as a computer network. A network is a collection of computers, servers, mainframes, network devices, or other interconnected devices that allow the sharing of data among themselves. An excellent example of a network is the Internet, which connects millions of people all over the world.

Types of Network

LAN (Local Area Network): -
Its full name is Local Area Network, a network that is used to connect two or more computers. A local area network is a locally functioning network, it is called a short lane. It is a computer network that covers local areas such as home, office, or building groups.

Features: -
    It is limited to one room or one building.
    It has high data transfer speed.
    It does not have to hire external networks.
    Data is safe in this.
    It is easy to organize data.

MAN (Metropolitan Area Network): -
Its full name is Metropolitan Area Network. It is a high-speed network that uses voice, data, and images at speeds up to 200 megabytes per second or more, 75 km. It can be carried to a distance of It is a network larger than LAN (LAN) and smaller than WAN (WAN). Through this network, one city is connected to another city.

Under this, two or more local area networks are connected together. It is a computer network located within the boundaries of a city. Routers, switches, and hubs together form a metropolitan area network.
Features: -
    It is difficult to maintain.
    It has a high speed.
    It is 75 km Spans a distance of
    3-man

WAN (Wide Area Network): -
Its full name is the Wide Area Network. It is a large network in terms of area. This network is not only limited to one building, not only one city, but it works to connect the whole world, ie it is the largest network in which data is sent and received securely. Computers in this network are connected by leased lines or switch circuits. The geographical periphery of this network is large such as the network of networks spread across the entire city, country or continent. The Internet is a good example of this. Banks' ATM facilities are an example of a wide area network.

Features: -
    It is a wireless network.
    In this, data can be sent and received by Signals or Sate light.
    It is the largest network.
    Through this, we can transfer data all over the world.
