History of Computers - ARPAnet
This page was created by Christian Segner
The Advanced Researching Projects Agency Network (ARPAnet) was the main component of a set that made up the global internet. The technology was created in 1968 by the Defense Advanced Projects Agency (DARPA) for use at Universities and research laboratories.

Overview
The origin of the internet started with J.C.R. Licklider becoming head of the computer research program at DARPA in October 1962. Licklider convinced his successors at DARPA (including Lawrence G. Roberts and Leonard Kleinrock) of the importance of the network project. In 1964, Roberts and Thomas Merrill created the first wide area computer network ever built. In August 1968, after Roberts and DARPA funded and refined the structure of ARPAnet, ARPAnet split off from DARPA and under the control of the BNN team and Bob Kahn. Bob Kahn played a major role in the architectural development and design of ARPAnet. [2]The first host computer of ARPAnet was installed at the Network Measurement Center at UCLA in September 1969. Later, secondary host computers were installed at UC Santa Barbara and the University of Utah. In December 1970, the initial ARPAnet Host-to-Host protocol was completed (Network Control Protocol or NCP). After the development of applications (including electronic mail) in 1972, an e-mail was sent and replied to from two different computers. That e-mail was a forerunner of what the world wide web does for us today.[3]
Significance
ARPAnet is historically significant because it provided the first step in the the eventual creation of the internet. Without the internet, modern society would look nothing like it does today. ARPAnet may not seem like much today, but something always to take the initiative to start moving in the right direction.
