The History of The Internet

The Internet began as a project of the U.S. Department of Defense in 1969. The project called the ARPANET or Advanced Research Projects Agency, used a collection of different computers to connect universities, military, government, and defense contractors. The word ARPA came from the
Advanced Research Projects Administration, the branch of the defense in charge of handing out grant money. Eventually, many universities joined this network of computers. The Department of Defense split the network into the MILNET for the military sites and the ARPANET for nonmilitary education use. Eventually, with technological advances such as the IP (internet protocol- which allowed many computers to share information) and the widespread support of the AT&T and University of California at Berkeley, UNIX operating software for networks, universities and other industries were beginning to connect to this network of computers. The National Science Foundation, set up the NSFNET (National Science Foundation Network) to link super computers to other computers all over the world.

However, by 1994 companies such as IBM, Sprint, AT&T, and MCI took over the backbone operation of the internet, and the internet has grown ever since. The growth of the internet measured by hosts (the computers attached to the internet’s physical network) has grown from 1,313,000 computers in January 1993 to 4,852,000 computers in January 1995.
