Basics
of Computer Science - Networking
A computer networking is a process of 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.
Advantages 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 States of America provides technical support to a person sitting in a
remote part of India.
Easy Sharing of Data
With the help of networking, it is very simple to share all
formats of digital data from one computer system to another (irrespective of
their geographic location).
Easy Sharing of Hardware Resource
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 computers 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 as 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 area (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 provided by public (government) agencies
as well as private 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).
