Internet

Internet is a network connecting many computer networks and based on a common addressing system and communications protocol.

The Internet has its origin in the US Department of Defence program called

Advanced Research Projects Agency Network. The program was created in order to provide a communications network for organizations dealing with defence research.

From its creation in 1983 the Internet has been growing into increasingly popular mass media. Nowadays it connects millions of computers throughout the world. The sphere of its usage has also been extended by the connecting of many other computer networks and the communications services. The original uses of the Internet were electronic mail (commonly called “E-mail”), file transfer, using file transfer protocol, newsgroups and remote computer access (telnet).

By 1990 the World-Wide Web, which enables simple navigation of the Internet sites through a graphical interface, had also extended greatly and became the most important component of the Internet.

The Internet connected millions of computers throughout the world. Many commercial computer network and data services also provided at least indirect connection to the Internet. Amateur radio, cable television wires, spread-spectrum radio, satellite and fibre optics all have been used to deliver Internet services. Networked games, networked monetary transactions and virtual museums are among applications being developed that both extend the network`s utility and test the limits of its technology.
