* ARPANET, the predecessor of the Internet

The network elements used to connect individual networks in the ARPANET, the predecessor of the Internet, were originally called gateways, but the term has been deprecated in this context, because of possible confusion with functionally different devices.

In 1969 the Stanford Research Institute operated one of the four original nodes that comprised ARPANET, predecessor to the Internet.

It was founded at the Massachusetts Institute of Technology Laboratory for Computer Science ( MIT / LCS ) with support from the European Commission and the Defense Advanced Research Projects Agency ( DARPA ), which had pioneered the Internet and its predecessor ARPANET.

Some of BBN's notable developments in the field of computer networks are the implementation and operation of the ARPANET ; the first person-to-person network email sent and the use of the @ sign in an email address ; the first Internet protocol router ( then called an Interface Message Processor ); the Voice Funnel, an early predecessor of voice over IP ; and work on the development of TCP.

He did much to actually initiate all that through his funding of research which led to a great deal of it, including today's canonical graphical user interface, and the ARPANET, the direct predecessor to the Internet.

The Network Control Program ( NCP ) provided the middle layers of the protocol stack running on host computers of the ARPANET, the predecessor to the modern Internet.

Clark had a small but key role in the planning for the ARPANET ( the predecessor to the Internet ).

The name arpa is a remnant of the ARPANET, one of the predecessor stages of today's Internet.

Engelbart's research was funded by DARPA, and SRI's ARC became involved with the ARPANET, the precursor of the Internet.

ARC also published a large percentage of the early Request For Comments, an ongoing series of publications that document the evolution of ARPANET into the Internet.

In addition to ARPANET, and its successor, the Internet, other early worldwide computer networks included Usenet and FidoNet from 1980s, both of which were used to support distributed discussion systems.

DARPA supported the evolution of the ARPANET ( the first wide-area packet switching network ), Packet Radio Network, Packet Satellite Network and ultimately, the Internet and research in the artificial intelligence fields of speech recognition and signal processing, including parts of Shakey the robot.

In the 1970s, ISI helped create Internet forerunner ARPANET, among other projects.

* 1969 – The first-ever computer-to-computer link is established on ARPANET, the precursor to the Internet.

Various aspects of OSI design evolved from experiences with the ARPANET, the fledgling Internet, NPLNET, EIN, CYCLADES network and the work in IFIP WG6. 1.

This particular computer was one of the 15 nodes on ARPANET, the computer network that would become the Internet.

In 1977, DARPA created a packet radio network called PRNET in the San Francisco Bay area and conducted a series of experiments with SRI to verify the use of ARPANET ( a precursor to the Internet ) communications protocols ( later known as IP ) over packet radio links between mobile and fixed network nodes.

Following the expiration of the original ARPANET contract with the U. S. federal government, the Internet Society ( acting on behalf of the IETF ) contracted with the Networking Division of the University of Southern California ( USC ) Information Sciences Institute ( ISI ) to assume the editorship and publishing responsibilities ( under the direction of the IAB ).

* ARPANET, an interactive computer-based information network that paved the way for the Internet

As a UCLA graduate student in the 1960s, Steve Crocker helped create the ARPANET protocols which were the foundation for today's Internet.

Development work continued throughout the 1970s, until the ARPANET converted into the modern Internet around 1980.

** TCP / IP test succeeds connecting 3 ARPANET nodes ( of 111 ), in what eventually becomes the Internet protocol.

** The first ARPANET link is established ( the progenitor of the global Internet ).

The practice of using a name as a simple memorable abstraction of a host's numerical address on a computer network dates back to the ARPANET era, before the advent of today's commercial Internet.

The rapid growth of the network made it impossible to maintain a centrally organized hostname registry and in 1983 the Domain Name System was introduced on the ARPANET and published by the Internet Engineering Task Force as RFC 882 and RFC 883.

* Internet-The Internet began as the ARPANET, a program funded by the U. S. military.

In complex networks constructed of multiple routing and switching nodes, like the ARPANET and the modern Internet, a series of packets sent from one host computer to another may follow different routes to reach the same destination.

The first message on the ARPANET was sent by UCLA student programmer Charley Kline, at 10: 30 p. m, on October 29, 1969 from Boelter Hall 3420.

Hence, the literal first message over the ARPANET was " lo ".

The first permanent ARPANET link was established on November 21, 1969, between the IMP at UCLA and the IMP at the Stanford Research Institute.

The intention was to leapfrog from the old DEC timesharing system SAIL was then running to a new generation, bypassing TENEX which at that time was the ARPANET standard.

Another factor on early ARPANET mailing lists was netiquette, wherein people asking questions typically " promised to ' summarize ' received answers.

Access to the ARPANET was expanded in 1981 when the National Science Foundation ( NSF ) developed the Computer Science Network ( CSNET ) and again in 1986 when NSFNET provided access to supercomputer sites in the United States from research and education organizations.

The ARPANET was decommissioned in 1990.

The migration of the ARPANET to TCP / IP was officially completed on flag day January 1, 1983, when the new protocols were permanently activated.

While at UCLA, he was involved in early work on the ARPANET.

These experiments were generally considered to be successful, and also marked the first demonstration of Internetworking, as in these experiments data was routed between the ARPANET, PRNET, and SATNET ( a satellite packet radio network ) networks.

Many of the subsequent RFCs of the 1970s also came from UCLA, because UCLA was one of the first Interface Message Processors ( IMPs ) on ARPANET.

The Augmentation Research Center ( ARC ) at Stanford Research Institute, directed by Douglas Engelbart, was another of the four first ARPANET nodes and the source of early RFCs.

The very first device that had fundamentally the same functionality as a router does today, was the Interface Message Processor ( IMP ); IMPs were the devices that made up the ARPANET, the first packet network.

By 1970, Stanford was home to a linear accelerator, and was one of the original four ARPANET nodes ( precursor to the internet ).

In 1974 the first realtime two-way LPC packet speech communication was accomplished over the ARPANET at 3500 bit / s between Culler-Harrison and Lincoln Laboratories.
