  2. 2. HISTORY OF THE INTERNET In 1962, J.C.R. Licklider of Massachusetts Institute of Technology (MIT) proposed a global network of computers for research and development in scientific and military fields.
  3. 3. HISTORY OF THE INTERNET Licklider moved to Defense Advanced Research Project Agency (DARPA) in late 1962 to head the work to develop the global network of computers.
  4. 4. HISTORY OF THE INTERNET Leonard Kleinrock of MIT developed the theory of packet switching, which was the basis for Internet connections.
  5. 5. HISTORY OF THE INTERNET Lawrence Roberts of MIT connected a Massachusetts computer with a California computer in1965 over a dial- up telephone lines, which showed the feasibility of WAN.
  6. 6. HISTORY OF THE INTERNET Kleinrocks packet switching theory was confirmed. Roberts moved over DARPA in 1966 and developed ARPANET.
  7. 7. HISTORY OF THE INTERNET ARPANET Advanced Research Project Agency Network
  8. 8. HISTORY OF THE INTERNET The Internet, then known as the ARPANET, was brought online in1969 initially connected four major computers in universities in the Southwestern US.
  9. 9. HISTORY OF THE INTERNET University of California in Los Angeles University of California in Santa Barbara
  10. 10. HISTORY OF THE INTERNET University of Utah Stanford Research Institute
  11. 11. HISTORY OF THE INTERNET Charley Kline at UCLA sent the first packets on ARPANET as he tried to connect to Stanford Research Institute on 29 October 1969.
  12. 12. HISTORY OF THE INTERNET Email was adapted for ARPANET by Ray Tomlinson in 1972. He picked the @ symbol to link username and address.
  13. 13. HISTORY OF THE INTERNET The telnet protocol was published as a Request for Comments (RFC) in 1972 to share developmental work throughout community.
  14. 14. HISTORY OF THE INTERNET The File Transfer Protocol (FTP) was published as an RFC in 1973. RFC became available to anyone who had use of the FTP.
  15. 15. HISTORY OF THE INTERNET Ethernet, a protocol for many local networks, appeared in 1974. It is an outgrowth of Harvard Student Bob Metcalfes dissertation on Packet Networks.
  16. 16. HISTORY OF THE INTERNET The Internet matured in the 70s as a result of the TCP/IP Architecture proposed and developed by Bob Kahn and Vint Cerf at Stanford Research Institute.
  17. 17. HISTORY OF THE INTERNET The TCP/IP was adopted by Defense Department in 1980 to replace the Network Control Protocol (NCP) and universally adopted by 1983.
  18. 18. HISTORY OF THE INTERNET In 1986, the National Science Foundation funded NSFNet as a cross country 56 Kbps backbone for the Internet.
  19. 19. HISTORY OF THE INTERNET The National Science Foundation maintained their sponsorship for nearly a decade, setting rules for its non-commercial government and research uses.
  20. 20. HISTORY OF THE INTERNET In 1989, Tim Berners-Lee proposed a new protocol for information distribution at the Center for European Nuclear Research (CERN) in Switzerland.
  21. 21. HISTORY OF THE INTERNET This protocol, which was based on hypertext (a system embedding links in text to link to other text) became the World Wide Web in 1991.
  22. 22. HISTORY OF THE INTERNET In 1991, the really first friendly interface to the Internet was developed at the University of Minnesota.
  23. 23. HISTORY OF THE INTERNET Prior to the Web, the Internet was all text, no graphics, no animations, no sound, or no video.
  24. 24. HISTORY OF THE INTERNET The development in 1993 of the graphical browser Mosaic by Marc Andreessen at the National Center for Supercomputing Applications (NCSA) gave the protocol its big boost.
  25. 25. HISTORY OF THE INTERNET Andreessen became the brains behind Netscape Corp., which produce the most successful graphical type of browser and server until Microsoft declared war and developed its Microsoft Internet Explorer.
  26. 26. HISTORY OF THE INTERNET Delphi was the first national commercial online service to offer Internet access to its subscriber. It opened up an email connection in July 1992 and full Internet service in November 1992.
  27. 27. HISTORY OF THE INTERNET The first generation of the Web, known as Web 1.0, focused on linking existing information.
  28. 28. HISTORY OF THE INTERNET In 2001, the second generation, Web 2.0, evolved to support more dynamic content creation and social interaction.
  29. 29. HISTORY OF THE INTERNET Web 3.0 focuses on computer generated information requiring less human interaction to locate and integrate information.
  30. 30. THE INTERNET VS. THE WEB The Internet is the actual network. It is made up of wires, cables, satellites, and rules for exchanging information.
  31. 31. THE INTERNET VS. THE WEB Being connected to this network is often described as being ONLINE.
  32. 32. THE INTERNET VS. THE WEB The Web is a multimedia interface to the resources throughout the world.
  33. 33. THE INTERNET VS. THE WEB Most Common Uses Communication Shopping Searching Education / E-Learning Entertainment
