The greatest invention

INTRODUCTORY

The internet is a worldwide network of thousands of computers and computers networks. It is a public, voluntary, and cooperative effort between the connected institutions and is not owned or operated by any single organization. 

The internet was initially developed in 1973 by American computer scientist Vinton Cerf as part of a project sponsored by the United States Department of Defense Advanced Research Projects Agency (ARPA) and directed by American engineer Robert Kahn.

HISTORY OF THE INTERNET

Many people think that the Internet is a recent innovation, when in fact the fundamental ideas behind the Internet have been around for over a quarter century.
The development of what we now call the Internet started in 1957 when the Soviet Union launched Sputnik 1, the first satellite, beating the United States into space. The powers behind the American military at the time became highly alarmed as this meant that the USSR could theoretically launch bombs into space, and then drop them anywhere on earth. In 1958 the concerns of people in the US military triggered the creation of the Defence Advanced Research Projects Agency (DARPA).

The design of the Internet was done in 1973 and published in 1974. It was about 10 years of hard work, resulting in the roll out of the internet in 1983.

HOW INTERNET WORKS

Internets are formed by connecting local networks through special computers in each network known as gateways. Gateway interconnections are made through various communication paths, including telephone lines, optical fibers, and radio links. Additional networks can be added by linking to new gateways. Information to be delivered to a remote machine is tagged with the computerized address of that particular machine.
