  2. The TCP/IP history • Internet concepts • Applications • Technology (TCP/IP) • Implications for • Individuals • Organizations • Society • Internet skills • Application development • Content creation • Text • Images • Audio • Video

  3. The vision Vannevar Bush’s “memex” from As We May Think, 1945

  4. The vision “In a few years, men will be able to communicate more effectively through a machine than face to face”. “What will on-line interactive communities be like? ... They will be communities not of common location, but of common interest. In each field, the overall community of interest will be large enough to support a comprehensive system of field-oriented programs and data”. Licklider and Taylor, On-Line Man Computer Communication, 1968 (revision of a 1962 conference paper)

  5. The vision Doug Engelbart, 1968, demonstrating systems designed to augment human intelligence (begun in 1962)

  6. The ARPANet -- December 5, 1969 • Connected dissimilar computers, not networks • Like a widely dispersed local area network • Like a LAN with Macs and Windows PCs

  7. TCP/IP motivation ARPA wanted to connect several separate, dissimilar networks to create an internetwork. Above is a figure from the paper proposing TCP, an internetworking protocol …

  8. A Protocol for Packet Network Intercommunication,” IEEE Trans on Comms, Vol Com-22, No 5 May 1974. Vinton G. Cerf Robert E. Kahn

  9. TCP demonstration, October 1977 Interconnected three networks: ARPANet, SATNet, and the San Francisco Bay area packet radio network

  10. TCP/IP milestones • March 1978, TCP split into TCP and IP because packet voice applications required fast transport without error checking (UDP) • January 1 1983, ARPAnet converts to TCP/IP, and splits into Milnet for operational applications and ARPANet for research • 1985, The U.S. National Science Foundation initiates the NSFNET program with the goal of connecting all US and many foreign universities • 1986, NSF deploys a six node network with 56 Kbps links using TCP/IP Which day was the “birth of the Internet?”

  11. Other early protocols • IBM System Network Architecture, 1974 • Digital Equipment Corporation DECNet, 1975 • International Organization for Standardization model, 1978

  12. Cool historic video Computer Networks – Robert Kahn describing the ARPANet, J. C. R. Licklidder on motivation and applications, and others. The Demo, Douglas Engelbart demonstrates personal computer and networking prototypes that inspired generations of products and research
