What is Internet ?
The internet in simple terms is a network of the
interlinked computer networking worldwide, which is accessible to the
general public. These interconnected computers work by transmitting data
through a special type of packet switching which is known as the IP or
the internet protocol.
Internet is such a huge network of several
different interlinked networks relating to the business, government,
academic, and even smaller domestic networks, therefore internet is
known as the network of all the other networks. These networks enable
the internet to be used for various important functions which include
the several means of communications like the file transfer, the online
chat and even the sharing of the documents and web sites on the WWW, or
the World Wide Web.
It is always mistaken said that the internet and
the World Wide Web are both the same terms, or are synonymous. Actually
there is a very significant difference between the two which has to be
clear to understand both the terms. The internet and World Wide Web are
both the networks yet; the internet is the network of the several
different computers which are connected through the linkage of the
accessories like the copper wires, the fiber optics and even the latest
wireless connections. However, the World Wide Web consists of the
interlinked collection of the information and documents which are taken
as the resource by the general public. These are then linked by the
website URLs and the hyperlinks. Therefore World Wide Web is one of the
services offered by the whole complicated and huge network of the
internet.
The use of IP in the Internet is the integral
part of the network, as they provide the services of the internet,
through different layers organization through the IP data packets. There
are other protocols that are the sub-classes of the IP itself, like the
TCP, and the HTTP.

INTERNET DEFINITION
A means of connecting a computer to any other computer anywhere in the world via dedicated routers and servers. When two computers are connected over the Internet, they can send and receive all kinds of information such as text, graphics, voice, video, and computer programs.
No one owns Internet, although several organizations the world over collaborate in its functioning and development. The high-speed, fiber-optic cables (called backbones) through which the bulk of the Internet data travels are owned by telephone companies in their respective countries. The Internet grew out of the Advanced Research Projects Agency's Wide Area Network (then called ARPANET) established by the US Department Of Defense in 1960s for collaboration in military research among business and government laboratories. Later universities and other US institutions connected to it. This resulted in ARPANET growing beyond everyone's expectations and acquiring the name 'Internet.' The development of hypertext based technology (called World Wide web, WWW, or just the Web) provided means of displaying text, graphics, and animations, and easy search and navigation tools that triggered Internet's explosive worldwide growth.
