Introduction

In the present scenario of Information Technology, Internet has become a popular mode of
communication. It has permeated all spheres of life. Internet shares information with anybody.
Anywhere in the world with a minimum amount of financial resources. Internet is the
combination of millions of computers. Connected together either through phone lines.
Ethernet ISDN or cable modems, etc. so that they can share information. The internet is really
a big network.
One of the scientists referred, Internet as an ‘ocean’, because of its enormity and power. Some
people are said to ‘surf’, ‘ride’ or ‘navigate’ the ‘net’. It is probably more accurate to say most
people begin to ‘swim’ through the Internet, until they find their own way. With the Internet,
the possibilities are endless. Some of them are mentioned below.
School children, for example in Delhi can ‘talk’ to their friends in Mumbai.
Teachers and administrators can have a conference with other colleagues thousands of kilometers
away. A professional on a business trip can access the computer in her or his home or office,
and then dispatch hundreds of messages with a few simple clicks. The students can get
information of any subject at anytime through Internet. The jobseekers can get information
on different kind of jobs all over the world. The students wish to take admission for higher
education can get information from different institutions in any part of the global. And these
are just the beginning with the Internet. The limits are only determined by how much you
want to take from it.

13.1 Internet-Brief History

The Internet was first started as an experiment by the United States Department of defense
in 1969. The United States military needed a way for its researchers to communicate and
share programs with one another over their computers. The defense computer researchers
developed the first long distance network of computers, which was called ARPANET (Advanced
Research Projects Agency—Network). Remote military sites were then ‘connected’ to one
another, via telephone lines. Universities and scientists saw the advantage of long distance
networking. They began to connect with ARPANET as well as to each other. Businesses and
private individuals then started connecting through the network of computers. Eventually
the massive network of networks developed, known as Internet.
Today, no individual, no corporation and no government owns the Internet—it is owned,
operated and maintained by all of those who use it. The Internet was first started as an
