Internet has revolutionized the world of computers and the world of communications that were never suspected previously. Discovery telegraph, telephone, radio, and computer is a series of scientific work that led to the creation of the Internet that is more integrated and more capable than the equipment. Internet has the ability to broadcast to the whole world, has a mechanism for information dissemination, and a medium for collaboration and interaction between individuals with the computer without being limited by geography.
The Internet is an example of the most successful investment business and its ongoing commitment to research following the development of information technology infrastructure. Starting with research packet switching (packet switching), government, industry and the academic community have collaborated effort to change and create this exciting new technology.
The Internet is a computer network established by the U.S. Department of Defense in 1969, through a project called ARPANET ARPA (Advanced Research Projects Agency Network), where they demonstrated how the hardware and software are UNIX-based computers, we can make communication within the infinity through the telephone line. ARPANET project designing a network, reliability, how much information can be transferred, and finally all the standards that they set into the embryo development of new protocols that are now known as TCP / IP (Transmission Control Protocol / Internet Protocol).
The initial goal of the project is built for military purposes. At that time the United States Department of Defense (U.S. Department of Defense) create a system of distributed computer network by connecting the computer in areas vital to tackle the problem in case of a 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 across the region, 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.
