"ARPA" is short for Advanced Research Projects Agency. One of his core institutions is the IPto Information Processing Technology Office, which has been paying attention to cg animation, network communication, supercomputers and other research topics.
Background:
In a sense, the internet can be said to be the product of the cold war between the United States and the Soviet Union. In the United States, the 1960s was a very special era. In the early 1960 s, the Cuban nuclear missile crisis occurred and the cold war between the United States and the Soviet Union warmed up. The threat of nuclear annihilation has become a topic in people's daily life.
At the same time that the United States blocked Cuba, the Vietnam War broke out and political crises occurred in many third world countries. Due to the stimulation of American federal funds and the influence of public fear, the "cold war in the laboratory" also began. People think that maintaining the leading position in science and technology will determine the outcome of the war.
The progress of science and technology depends on the development of computer field. By the end of 1960s, every major federally funded research center, including purely commercial organizations and universities, had the latest computer equipment provided by the emerging computer industry in the United States. The idea of sharing data among computer centers is developing rapidly.
Viewpoint:
The U.S. Department of Defense believes that if there is only one centralized military command center, in case this center is destroyed by the nuclear weapons of the former Soviet Union, the military command of the whole country will be paralyzed and the consequences will be unimaginable. Therefore, it is necessary to design such a decentralized command system consisting of decentralized command points. When some command points are destroyed, others can still work normally, and these scattered points can get in touch through some form of communication network.
