  • 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

  • What about children's access to online material?
  • Or threats to yourpersonal privacy?
