1980s Telecommunications

      In this decade, Transmissions Control Protocol/Internet Protocol (TCP/IP), a set of rules governing how networks making up the ARPANET communicate, was established. For the first time, the term Internet was being used to describe the ARPANET. Security became a concern, as viruses appeared and electronic break-ins occurred. The 1980s saw the Internet grow beyond a research orientation to include business applications and a wide range of users. As the internet grew, the Domain Name System (DNS) was developed, to allow the network to expand more easily by assigning names to host computers in a distributed fashion.

CSNET, 1980

• CSNET stands for Computer Science Network.
• CSNET was connected all university computer science departments in United States.
• Existed in 1980, computer science department were relatively new and only a limited number.
• CSNET joined the ARPANET in 1981.

BITNET, 1981

• BITNET stands for Because It�s Time Network.
• BITNET formed at the City University of New York and connected to Yale University.
• Many mailing lists originated with BITNET

TCP/IP, 1983

• TCP/IP stands for Transmission Control Protocol/ Internet Protocol.
• The United States Defense Communications Agency required that TCP/IP be used for all ARPANET hosts.
• Since TCP/IP was distributed at no charge, the Internet became what is called an open system.
• This allowed the Internet to grow quickly and connected computers were now �speaking at the same language�.

Back

NSFNET, 1985

• NSFNET stands for National Science Foundation Network.
• NSFNET was formed to connect the National Science Foundation�s (NSF�s) five supercomputing centers.
• Researchers to access the most powerful computers in the world, when large, powerful and expensive computers were a rarity and generally inaccessible.

The Internet Worm and IRC, 1988

• Robert Morris was a computer science graduate student at Cornell University, which created the virus called Internet Worm, was released.
• It infected ten percent of all Internet hosts.
• Internet Relay Chat (IRC) was written by Jarkko Oikarinen, also in this year.

NSF Assumes Control of the ARPANET, 1989

• In 1989, NSF took over control of the ARPANET.
• This changeover went unnoticed by nearly all users.
• The number of hosts on the Internet exceeded the 100,000 mark.
