The document discusses the history and evolution of the Internet. It began as a precursor technology called ARPANET, developed by the US Department of Defense in the 1960s. In the 1990s, Tim Berners-Lee invented the World Wide Web, introducing hyperlinks and URLs that allowed information to be shared over the Internet in a more interactive way. The introduction of graphical web browsers in the mid-1990s, such as Mosaic and Netscape, helped popularize the Internet. Internet usage then exploded from 1994-2000 as major websites like Amazon were launched and people began shopping and browsing online. The future of the Internet will focus on high-speed academic networks to support continued innovation.

To a lesser degree, broadcast media
such as radio and television

6. Evolution of the Internet

7. ARPANET
• Was the world's first operational
network, and the predecessor
of the global Internet

8. ARPANET
• ARPANET was developed by the U.S.
Department of Defense. One theory
was that it was developed to survive a
nuclear attack. That theory is often
disputed by scientists.

9. The Internet was an Accident!
• The Internet was a result of an
unsuccessful military and academic
research program!

10. Why is it called the Internet?
• Short for “internetworking.”

11. The World Wide Web

12. • The original Internet provided screens
full of text
• Great for sharing info and accessing the
Library of Congress
• Text was all one font and size
• BORING!

13. GUIs
(Graphical User Interface)
• GUIs added some color and layout, but
still were not very interesting.

14. The World Wide Web Saved
the Internet!
• Hyperlinks were invented
www.stmsaints.com
• The mouse was invented to click on
hyperlinks
• The URL (Uniform Resource Locater)
was invented. This allowed sites to be
named.

15. Creation of the World Wide Web
• Tim Berners Lee brought all of this
together to form the World Wide Web in
1990.

16. Mosaic: The First Web
Browser
• Very slow
• Did not handle loading pictures very
well
• Modems were very slow
• Did not give an indication of the
potential of this medium

17. 1994 – A Big Year for the WWW
• Tim Berners Lee in develops the World
Wide Web Consortium to develop
standards for the Web
• Netscape is founded

18. The Explosion of the Internet

19. 1994 -- 2000
• The Internet exploded during this
period.
• The first commercial site was
Amazon.com.
• In 1994 the World Wide Web grew by
an astounding 2300 percent!
• Amazon saw that online shopping was
the wave of the future.
• The rest is history…

20. Browser Wars
• Netscape was the standard until 1998
• It folded and was taken over by AOL
• Microsoft Internet Explorer snagged
96% of the browser market
• IE has only recently been challenged by
the excellent Mozilla browser

21. Future of the Internet

22. Future of the Internet
• So many businesses and private
citizens have come online that
academic users can't get the high-
speed connections they need.

23. Future of the Internet
• Organized as a consortium
• Led by over 200 universities
• Dedicated network for educational and
research purposes
