Internet - Histroy and Evolution


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.
