This document provides an overview of the internet including its history and development. It explains that the internet began as ARPANET, a network created by the US Department of Defense in the 1960s to enable communication between computers and survive a nuclear attack. Key developments include the creation of TCP/IP in the 1970s and the conversion of ARPANET to this protocol in 1984. The document also outlines basic internet services like email and the world wide web, advantages like speed and convenience, as well as some disadvantages like enabling cybercrimes. It traces the dramatic growth of internet hosts from the 1960s to present.

Hyper Text Markup Language (html)

6. How did the Internet
developed?
 Internet was born in late 1960’s
 The internet has its root in the ARPANET
system of the Advanced Research Project
Agency of U.S. Department of Defense which
linked together mainframe computers to form a
communication networks. 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.
 ARPANET is known as the forefather of
internet.

7. HISTORY
 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

14. Growth of the Internet
 1977: 111 hosts on Internet

 1983: 562 hosts
 1984: 1,000 hosts
 1986: 5,000 hosts
 1987: 10,000 hosts
 1989: 100,000 hosts
 1992: 1,000,000 hosts
 2001: 150 – 175 million hosts
 2002: over 200 million hosts
 By 2020, about 90% of the planet will be on the

15. The Internet was a result of an unsuccessful military and
academic research program!
Why is it called the Internet?
Short for “internetworking.”
The original Internet provided screens full of text
Great for sharing info and accessing the Library of Congress

BORING!
GUIs (Graphical User Interface) added some color and
