History of the Internet

The Internet is a computer network established by the U.S. Department of Defense in 1969, through a project called ARPANET ARPA (Advanced Research Project Agency Network), where they demonstrated how the computer hardware and software based on UNIX, we can make communication within the infinity through the telephone line.

ARPANET project designing a network, reliability, how much information can be transferred, and eventually all of the standards that they set into the embryo development of a new protocol which is now known as TCP / IP (Transmission Control Protocol / Internet Protocol).

The initial purpose of the project was built for military purposes. At that time the Department of Defense of the United States (U.S. Department of Defense) create a system of computer networks to connect computers scattered in areas vital to tackle the problem in case of nuclear attack and to avoid centralized information, which in the event of war can easily be destroyed.

At first ARPANET only 4 sites linking only the Stanford Research Institute, University of California, Santa Barbara, University of Utah, where they form an integrated network in 1969, and in general the ARPANET was introduced in October 1972. Not long after the project is growing rapidly in all regions, and all universities in the country wants to join, thus making it difficult to set the ARPANET.

Therefore ARPANET split widened two, namely "MILNET" for military purposes and the "ARPANET" new smaller for non-military purposes, such as universities. Combined both networks eventually known as the DARPA Internet, which then reduces to the Internet.
