The Internet represents one of the most successful examples of the benefits of sustained investment and commitment to research and development of information infrastructure. It is one of the most outstanding innovations in the field of communication in the history of mankind. Beginning with the early research in packet switching, the government, industry and academia have been partners in evolving and deploying this exciting new technology. By 1985, Internet was already well established as a technology supporting a broad community of researchers and developers, and was beginning to be used by other communities for daily computer communications. Electronic mail was being used broadly across several communities, often with different systems, but interconnection between different mail systems was demonstrating the utility of broad based electronic communications between people. The Internet has revolutionized the computer and communications world like nothing before. The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. The Internet is at once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard to geographic location. Brief history of the internet

The vast, global internet of today had rather humble origins when it initiated. In 1969, the Department of Defense Advanced Research Projects Agency (ARPA) developed an experimental network called ARPAnet to link together four supercomputing centres for military research. This network had the many and difficult design requirements that it had to be fast, reliable, and capable of withstanding a nuclear bomb destroying any one computer center on the network. From those original four computers, this network evolved into the sprawling network of millions of computers we know today as the internet. The Internet model and the Transmission Control Protocols used to implement the idea were developed by Vinton Cerf, an American computer scientist. His project was directed by Robert Khan, an American engineer. "The design of the Internet was done in 1973 and published in 1974. There ensued about 10 years of hard work, resulting in the roll out of Internet in 1983. Prior to that, a number of demonstrations were made of the technology - such as the first three-network interconnection demonstrated in November 1977 linking SATNET, PRNET and ARPANET. However, in 1991 the Internet changed again. That year, a computer programmer in Switzerland named Tim Berners-Lee introduced the World Wide Web: an Internet that was not simply a way to send files from one place to another but was itself a “web” of information that anyone on the Internet could retrieve. Berners-Lee created the Internet that we know today.

Since then, the Internet has changed in many ways. In 1992, a group of students and researchers at the University of Illinois developed a sophisticated browser that they called Mosaic. (It later became Netscape.) Mosaic offered a user-friendly way to search the Web: It allowed users to see words and pictures on the same page for the first time and to navigate using scrollbars and clickable links. That same year, Congress decided that the Web could be used for commercial purposes. As a result, companies of all kinds hurried to set up websites of their own, and e-commerce entrepreneurs began to use the Internet to sell goods directly to customers. More recently, social networking sites like Face book have become a popular way for people of all ages to stay connected.

Internet is a worldwide, publicly accessible network of interconnected computer networks that allows sharing or networking of files and information at remote...
