In today‘s world of extreme
competition on the business front, information exchange and efficient
communication is the need of the day. The internet is the highway that connects
you to millions of computer together globally,

forming networks in which any
computer can communicate with any other computer as long as they are both
connected to internet. The web is an increasingly important resource in many
aspects of life: education, employment, government, commerce, health care,
recreation, and more. With an internet, a user views web page that may contain
text, images, videos, and other multimedia and navigates between them is using
hyperlinks. The web provides an easy to use exciting, multimedia interface to connect
to the internet and to access the resources available in cyberspace. 

The Internet grew out of an experiment
in the 1960s by the U.S.  Department of
Defense (DOD). This year is also birth of internet. The DOD wanted to create a
computer network that would continue to function in the event of a disaster,
such as a nuclear war. If part of the network was damaged or destroyed, the
rest of the system still had to work. That network was ARPANET, (Advanced
Research Projects Agency Network) which linked U.S. scientific and academic
researchers. It was the forerunner of today’s Internet.

In 1972, Ray
Tomlinson of BBN [Bolt Beranek and Newman] created the first e-mail programmed
was currently using the Network Control Protocol [NCP] to transfer data,
allowing communications between hosts running on the same network. There are 15
nodes (23 hosts) on ARPANET.
In 1973 DARPA [Defense Advance
Research Project Agency] was developed new protocol name as Transmission
Control Program (TCP) which is basic of network inter communications. And telnet
is opened for commercial use of public packet data service. In 1977, electronic
mail services are opened to 100 researchers in computer sciences using locally
developed e-mail system and TELNET for access to server. In 1980, NSFNET
[National Science Foundation Network] is program of coordinating, evaluating
projects sponsored by NSF to promote advance research and evaluation in network
in United State for creation of super computer, plus satellite and radio
connections developed for network intercommunication. There are more than 56,000
users are using internet. In 1990 to 1995 growth of internet user increased up to
6,642,000 users.
