1 ARPANET Austin Paul

2 What is ARPANET?  Initiative of DARPA  Defense/Advanced Research Project Agency  It was the first functional packet switching network  ARPANET’s creation laid the groundwork for what later became the internet 1

3 History  Several different scientists were studying the ideas of packet switching independently  They eventually came together to advance their ideas as a team  The scientists were eventually able to establish a network that allowed computers to communicate with each other.  ARPANET is the name of the network

4 Computers  UCLA’s Sigma 7  Stanford Research Institute’s SDS-90 computer  University of California’s IBM 360/75  University of Utah’s DEC PDP-10 23

5 Purpose  The ARPANET designers wanted to create a way for individual computers to quickly and efficiently communicate  Messages travel across the network through  ARPANET essentially allowed various host computers to “talk” with eachother

6 Funding  ARPANET was primarily funded by the Pentagon  Then Senator Al Gore sponsored a bill titled the High Performance Computing and Communication Act of 1991  This bill helped establish additional funding for ARPANET and it opened the program for additional uses

7 Myths  Many argue that ARPANET was created in order to allow information sharing after a nuclear attack  This claim has been denied by a wide variety of groups, including the Internet Society  While ARPANET could have served as a communications network after a nuclear attack, that was not its goal 4

8 Major Breakthroughs  October 29, 1969  The first message was sent from UCLA to Stanford at 10:30pm on this date  Over the next several weeks the program expanded and by December the first four node network was established 5

9 Operating Period  ARPANET was in operation for most of the 1970s and 1980s.  It eventually spanned the continent and allowed for information sharing between universities and agencies across the country. 6

10 Successors  By 1988, ARPANET had been replaced by NSFNET  The National Science Foundation Network  This was the principle backbone of the internet  The world wide web itself is an immediate successor of ARPANET 7

11 Legacy  ARPANET contributed to one of the greatest technological advancements in the history of man kind  The successes of this technology helped establish a foundation for the practical application of computer networks  It can be argued that had ARPANET not been commissioned, the establishment of the internet would have been significantly delayed
