Presentation Transcript

  1. Action & Reaction • Oct 4th, 1957: USSR launches Sputnik 1 • Sets precedence for advancement in science and technology • USA forms Advanced Research Programs Agency (ARPA) • Later named Defense ARPA (DARPA)

  2. J.C.R. Licklider: The Visionary • MIT Researcher who envisioned a “Galactic Network” • Globally interconnected set of computers • Everyone could quickly access data and programs from any site • October of 1962, became 1st head of Computer Research at DARPA

  3. Paul Baran of RAND Corporation "Packet switching is the breaking down of data into datagrams or packets that are labeled to indicate the origin and the destination of the information and the forwarding of these packets from one computer to another computer until the information arrives at its final destination computer. This was crucial to the realization of a computer network. If packets are lost at any given point, the message can be resent by the originator."

  4. APRANET Structure
