  • The Telegraph
  • Invented in the 1840s.
  • Signals sent over wires that were established over vast distances
  • Used extensively by the U.S. Government during the American Civil War, 1861 - 1865
  • Morse Code was dots and dashes, or short signals and long signals
  • The electronic signal standard of +/- 15 v. is still used in network interface cards today.

What Is the Internet?

 

  • A network of networks, joining many government, university and private computers together and providing an infrastructure for the use of E-mail, bulletin boards, file archives, hypertext documents, databases and other computational resources
  • The vast collection of computer networks which form and act as a single huge network for transport of data and messages across distances which can be anywhere from the same office to anywhere in the world.
  • The largest network of networks in the world.
  • Uses TCP/IP protocols and packet switching .
  • Runs on any communications substrate.

 

What is the Internet?

 

From Dr. Vinton Cerf, 

Co-Creator of TCP/IP

Brief History of the Internet

 

  • 1968 - DARPA (Defense Advanced Research Projects Agency) contracts with BBN (Bolt, Beranek & Newman) to create ARPAnet
  • 1970 - First five nodes:
    • UCLA
    • Stanford
    • UC Santa Barbara
    • U of Utah, and
    • BBN
  • 1974 - TCP specification by Vint Cerf
  • 1984 – On January 1, the Internet with its 1000 hosts converts en masse to using TCP/IP for its messaging

The Creation of the Internet

 

  • The creation of the Internet solved the following challenges:
    • Basically inventing digital networking as we know it
    • Survivability of an infrastructure to send / receive high-speed electronic messages
    • Reliability of computer messaging

 

Internet grown UP

 

Since the mid-1990s the Internet  has had a drastic impact on culture  and commerce, including the rise of near-instant  communication by electronic mail, instant messaging,  Voice over Internet Protocol (VoIP) "phone  calls", two-way interactive video calls,  and the World Wide Web with its discussion  forums, blogs, social networking, and online  shopping sites. The research and education  community continues to develop and use  advanced networks such as NSF's very high  speed Backbone Network Service (vBNS), Internet2,  and National LambdaRail. Increasing amounts  of data are transmitted at higher and  higher speeds over fiber optic networks  operating at 1-Gbit/s, 10-Gbit/s, or more.  The Internet continues to grow, driven  by ever greater amounts of online information  and knowledge, commerce, entertainment and  social networking.
