Internet History

Internet was first discovered in the form of a computer network established by the United States Department of Defense in 1969, through a project called ARPA called ARPANET (Advanced Research Project Agency Network). The main project was built for military purposes. At that time the United States Department of Defense (U.S. Department of Defense) create a computer network system that is spread by linking computers in areas vital to overcome the problem occurs when a nuclear attack and to avoid the occurrence of centralized information, which in the event of war can be easily destroyed.
At first ARPANET link is only just 4 sites of the Stanford Research Institute, University of California, Santa Barbara, University of Utah, where they form a single 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 the universities in these countries want to join, thus making it difficult to arrange the ARPANET.
Therefore manjadi ARPANET split in 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.
