What is ARPANET Project


ARPANET (Advanced Research Projects Agency Network) is the world's first packet distribution network developed by ARPA (Unit of Advanced Defense Research Projects) affiliated to the United States Department of Defense and is the pioneer of universal Internet.

The first thoughts about a computer network that allows many computer users to communicate with each other were published in August 1962 by Bolt, Beranek and Newman (BBN), J.C.R. Licklider introduced the concept of "Galaxy Network". All the features that the Internet has today are determined during this study.
Today, packet distribution, seen as the worldwide dominant base of data and voice communications, functions as a new and important concept in data communications. Prior to that, data communication was based on circuit distribution. In this method, which resembles old telephone circuits, it was impossible for one end of the phone to communicate with someone else on the other end of the line until the end of the talk time.
In order to be able to communicate with multiple machines using a single communication line, a system in a package distribution method had to be divided into small pieces and then arranged in packages. The link can be shared on this vantage point (as if several letters were sent to different destinations from a single post office) and each package could be sent independently of the other packages.

A package delivery method developed by Larry Roberts of the Lincoln Laboratory scientists is the basis for the design of ARPANET.

In the late 1960s and early 1970s, packet-switched networks such as ARPANET, NPL network, CYCLADES, Merit Network, Tymnet and Telenet were developed using a variety of communication protocols. Donald Davies was the first person in the UK's National Physics Laboratory to turn packet switched network theory into practice by setting up a packet-switched network, a first in its class in the world. This work was a touchstone for the next 20 years of work in the UK itself.
