  2. The History of Internet 1957 • Soviet Union launches Sputnik I, the first artificial satellite. 1958 • President Eisenhower reacts by forming two government agencies to advance space technologies, weapons, and communication systems. • Advanced Research Projects Agency (ARPA) and National Aeronautics and Space Administration (NASA) are established.

  3. 1969 • The first ARPANET connections are made. Nodes (hosts) are set as 516 minicomputer with 12K memory, set with 50 kbps lines, which AT&T provides. • Node 1: UCLA (September) • Node 2: Stanford Research Institute (SRI) (October) • Node 3: University of California Santa Barbara (UCSB) (November) • Node 4: University of Utah (December)

  4. 1970 • ARPANET hosts start using NCP, or Network Control Protocol, further developing the first host-to-host protocol. 1972 • RayTomlinson modifies his email program for ARPANET and quickly gains popularity. Initially there were some variations of the program, but the "@" was finally chosen as the standard. 1973 • ARPA changes its name to DARPA • ARPANET makes its first international connection to the University College of London (England) and the Royal Establishment in Norway (NORSAR).

  5. 1980 • Due to virus ARPANET comes to a complete halt. • ARPANET has 213 hosts, with a new host added approximately once every 20 days. • The system serves as a cooperative network between the City University of New York and Yale. The low-cost network later expands throughout United States and to overseas. 1975 • Satellite links across two oceans to Hawaii and UK are formed, and the first TCP tests are layered over them by Stanford, BBN, and UCL. 1976 • Queen Elizabeth II makes early network history by sending an email announcing that the Royal Signals and Radar Establishment in Malvern, is available on the ARPANET system.

  6. 1982 • DCA (Defense Communication Agency) and DARPA establish the Transmission Control Protocol (TCP) and Internet Protocol (IP) and the protocol suite, commonly known as TCP/IP for ARPANET. • DOD also declares TCP/IP as a standard. 1984 • Domain Name System or DNS is introduced to identify the type of institution which represents the host

  7. 1988 • Internet Relay Chat (IRC) is developed by Jarkko Oikarinen. 1991 • WAIS, invented by Brewster Kahle, is released by Thinking Machines Corporation. • Gopher is introduced by Paul Lindner and Mark P. McCahill from the University of Minnesota. • World-Wide Web (WWW) is released by CERN in Geneva, Switzerland. • British researcher, Tim Berner-Lee creates HTML • The web as we know it is born!

  8. 1992 • World Bankcomes on-line • Theterm "surfingthe Internet" is coinedby Jean ArmourPolly 1993 • US White House (http://www.whitehouse.gov), and United Nations (UN) comes on-line • Countriesconnectingto NSFNET: Bulgaria (BG), Costa Rica (CR), Egypt (EG), Fiji (FJ), Ghana (GH), Guam (GU), Indonesia (ID), Kazakhstan (KZ), Kenya (KE), Liechtenstein (LI), Peru (PE), Romania (RO), RussianFederation (RU), Turkey (TR), Ukraine (UA), UAE (AE), US VirginIslands (VI)

  15. What is the Internet? • “An internet is a network of networks” says Kevin Hughes • The term was coined for the ARPANET to describe a collection of different networksthat all used TCP/IP. • Internet Society described “a way to communicate and share resources”

Who Runs the Internet? The short answer is "no one". Who Provides Access Outsidethe USA? There are now a large number of backbone and mid-level networks in other countries.
