Basic of Computer Science – Networking

A computer networking is a process connecting two more than two computers with the purpose to share data, provide technical support, and to communicate (especially for the business purpose).

Internet is the technology that is used to connect different computer systems (located in different geographic location). Networking technology has revolutionized the world and created a new arena for the overall development of every nation.

Advantage of Networking

Let us now discuss the advantages of networking. The advantages are described below –

Facility of Technical Support

Because of having computer networking, a person sitting in the United State of America provides technical support to a person sitting in a remote part of  India.

Easy Sharing of Data

With the help of networking, simple to share all formats of digital data from one computer system to another (irrespective of their geographic location).

Easy of Sharing of Hardware Resources

 With the help of networking, it has now become very simple to share the expensive resources including storage space, processor, fax, etc.

 Easy Sharing Software

Through the networking system, it is easy to share and install the software from one computer system to another computer system.

Easy to Decentralize  Data Processing

Through the networking system, it is very simple to decentralize the data processing system. It ultimately helps to control, secure, and manage the important data.

Easy to communicate

With the help of networking, the communication system has now become highly efficient, frugal, and fast. The different modes of communication are text chatting, video chatting, emails, etc.

Types of Network

In this section, we will discuss the different types of network. The types are described below –

• Local area Network (LAN)

• Metropolitan Area Network (MAN)

• Wide Area Network (WAN)

Local Area Network

Local Area Network or simply LAN is the technique of interconnecting a few computer located in a given premise. It is normally used for a single business office or a residential apartment.

The major purpose of such interconnectivity is to establish a communication system in order to make the work easier.

However, in such connectivity, some other devices can also be attached such laser printers, fax, machine, etc.

Metropolitan Area Network

Metropolitan Area Network or simply MAN is a system of network that normally covers a large metropolitan are (city part).

It provides high speed Internet services throughout the area covered within the network.

Wide Area Network

Wide Area Network or simply WAN is a system of network that covers a large geographical area across the world.

The services of WAN are provides by public (government) agencies as well as privates agencies. The network also provides the facility to access databases located remotely.

The WAN system is highly beneficial for MNCs and other big corporate companies (offering online services).
