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).
