 * The ARPAnet began to be constructed in 1967 during the cold war. The military was the first to use it. It was designed to be used for nuclear missiles. Surviving network losses was also why it was invented. It was also a link of geographical computers for scientists to be able to connect with each other. It was was invented for military purposes only . With the use of circuit switching, data could be sent to different computers, like a basic telephone circuit.It also used packet switching, which allowed communications to be sent to more than one machine by using data-grams and transmitting them to packets into the network link, when it is not in use. So, not only the link was shared, but also could be independent to other files. The first idea of this network was in 1962 by computer scientist J. C. R. Licklider of the company Bolt, Barnek, and Newman, Or BBN. The complete plan was finished in 1968. The ARPAnet was not released to the public until 1969. The first message that was sent was supposed to be login, but after the letters l and o were typed, the computer crashed, so technically the first message sent from a computer to another was "lo". The ARPAnet was shut down but the IMP addresses remained up as late as 1989. (paragraph 1: 15 facts)[|Youtube] **
