What Was the
- 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.

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:
- UC Santa Barbara
- U of Utah, and
- 1974 - TCP specification by Vint Cerf

A Brief Summary of the
Evolution of the Internet
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
