Study Notes

1.1 History of Networking and the Internet

  • Networking concept originated in 1962 by J.C.R. Licklider
  • First wide area network (WAN) created in 1965, connecting a TX-2 computer in Mass to a Q-32 in California
  • ARPANET (Advanced Research Projects Agency Network) developed in 1969 by the US Department of Defense, becoming the first internet built by the US government
  • ARPANET publicly demonstrated at an international conference in 1972
  • Internet growth: 11,000 servers(1987), 200,000 servers (1989), >1,000,000 servers and >1 billion users and 500 million computers (as of early 1990s).
  • Internet primarily used for information sharing.

Requirements for Internet Connection

  • Powerful computer machine
  • Windows operating system (Windows 95 and above)
  • Sufficient RAM

1.2 Basic Key Words in the Internet

  • WWW (World Wide Web): global information access system
