How did Internet start? • In 1969, during Cold War, Internet created by Department of Defenseto exchange data and text messages between mainframe computers • This network of computers, starting with a link between UCLA and Stanford, began to grow to help academic and military researchers share data with one another through a protocol called TCP/IP • TCP/IP is your connection software—what actually goes out and connects to the other computers in the world, gets Web pages and feeds them to your browser

  6. What was original Internet like? • Only text documents; difficult to use • This internetwork of computers would function even if major segments were knocked out by a nuclear attack or saboteurs • If any distribution point was overloaded or knocked out, messages could be rerouted through other distribution points
