INTERNET

Internet is a network connecting many computer networks and based on a common addressing system and communications protocol. From its creation in 1983 it grew into an increasingly popular medium.

The original uses of the Internet were electronic mail (commonly called “E-mail”), file transfer, using file transfer protocol, bulletin boards and newsgroups, and remote computer access (telnet).

The World-Wide Web, which enables simple navigation of the Internet sites through a graphical interface, expanded during the 1990’s to become the most important component of the Internet.

By the mid-1990’s 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.

The Internet had its origin in U.S. Department of Defense program called ARPANEIdvanced Research Project Agency Network).

It was established in 1969 to provide a communications network for organizations connected with defense-related research.

Researchers and academics in other fields began to make use of the network, and at length the National Science Foundation (NSF), which had created a similar and parallel network, called NSFNet, took over much of the technology from ARPANET and established a distributed network of networks capable of handling far greater traffic. NSF continues to maintain the backbone of the network (which carries data at a rate of 45 million bits per second), but Internet protocol development is governed by the Internet Architecture Board.

Amateur radio, cable television wires, spread-spectrum radio, satellite, and fiber 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.
