The Creation of the Internet and its Development.

Main Points When was the Internet created and why? What was ARPAnet? The need of TCP/IP FSFnet The End of ARPAnet?

When was the Internet created and Why? 1962 the year of Cuban Missle crisis. 1964 Paul Baran of RAND Corporation proposed a decentralized system

When was the Internet created and Why? Lawrence Robert improved Paul Baran’s design into what we know today as Packet Switching System. 1969 ARPAnet was created.

What was ARPAnet? An Experimental network. A military project. Foundation of the Internet.

The First Node connected to ARPAnet. The first node was installed at the University of California Los Angeles on 01-09-1969

The original ARPAnet. 01/10/1969 Stanford Research Institute (SRI) 01/12/1969 University of UTAH (UTAH) 01/11/1969 University of California Santa Barbara (UCSB) 01/09/1969 University of California Los Angeles (UCLA)

More users connected to ARPAnet. In 1972 ARPAnet made its first public appearance during the International Conference on Computers and Communication. More users were being connected to ARPAnet.

More users connected to ARPAnet. Researchers realized that a new protocol was needed, which was able to connect multiple computer networks together.

The TCP/IP was created. Between 1973 and 1978 a group of researchers led by Vinton Cerf of Stanford Research Institute and Robert Kahn of DARPA created the TCP/IP or Transmission Control Protocol. In 1983 TCP/IP fully replaced NCP.

ARPAnet was divided into 2. MILnet – an unclassified network reserved only for military purposes. ARPAnet – continued to be a research and development network.

The Last Days of ARPAnet. In 1986 NSFnet was created and named for the National Science Foundation. NSFnet offered fastest connection when compared to ARPAnet In 1990 Arpanet was officially closed down.

The World Wide Web In 1991 the WWW was released by CERN The Internet as we know it today was born.

Conclusion Paul Baran was the first researcher to propose a decentralized system. In 1969 ARPAnet was build up. In 1983 TCP/IP fully replaced the NCP In 1986 NSFnet was created In 1990 ARPAnet was officially ceased.
