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.

What is Computer Networking?

When two or more computers are connected through any communication channel, it is called Computer Network. Computer networks are generally of three types: LAN (Local Area Network), MAN (Metropolitan Area Network), and WAN (Wide Area Network). In a network, different types of computers are connected together and users work together in a group. Database management systems, as well as software packages in graphical artwork, have been developed for group work. Apart from this, data can be transferred and stored on the central computer from different departments located in faraway places. This data can be used by computers located in different departments. Central computer data can be updated and used by all users. This method can prevent any obstacles in the smooth running of the organization as all the users get the latest information stored in the central computer.

Applications of Network

Networking has contributed a lot in today's era. Below are some examples that are not possible without networking.

As the business grows, good communication between employees is required. Organizations can improve efficiency by sharing information such as common files, databases, and business application software over a computer network. Following are the benefits of using the network:

The exchange of data in electronic form accelerates the functioning and saves time.

Hardware devices are used jointly by many computers, so computerization reduces costs.

Many people can get one data and information at a time, so there is no need to exchange data and information.

A user may not be able to buy all the expensive tools but he can use any type of tools as necessary with the help of the network. The user can run his work at very low cost.
