History of the internet • The internet first came about in February 1958 in America • A man named JCR Licklider saw universal networking as a potential unifying revolution. • He envisioned a globally interconnected set of computers through which everyone could quickly access data and programs from any site. • Leonard Kleinrock at MIT published the first paper on packet switching theory in July 1961 and the first book on the subject in 1964. • The internet began to grow rapidly in the 1970’s as the knowledge of networking was growing more and more rapidly. • It expanded further in the 1980’s as the general public were becoming more aware of it.

Countries around the world joined the Internet and registered their two-letter domain names, e.g. ca for Canada. •The most important development was in 1993 was the release of the first graphic web browser software, Mosaic.

The first shopping malls also appeared along with Internet radio stations (mainly rebroadcasting) and the first cyber bank. • In 1998, the Internet continued to grow, with thousands of new subscribers every day joining the millions already subscribed.
- 5. What is it? • The Internet is a worldwide, publicly accessible network of interconnected computer networks that transmit data using the standard Internet Protocol (IP). • It’s a worldwide network of computers that allows the "sharing" or "networking" of information at remote sites from other academic institutions, research institutes, private companies, government agencies, and individuals. • It allows people to send and receive data wherever they are in the world if they have internet access • Everyone will find that they use the internet in one way or another, whether it is to research some information or simply talk to friends • Today, the Web and the Internet allow connectivity from literally everywhere on earth—even ships at sea and in outer space.
- 6. Audience • The intended audience for the internet is anyone and everyone in the world who has access to a computer, there is no limit to the information that can be found on the internet. • The internet is used widely by the audience, mostly it used for researching subjects and talking online.
