Changes

The realization of the vision of LIcklider for the ARPANET as universal communication network became evident in September 1969 when Leonard Kleinrock, head of the Network Measurement Center ([[NMC]]) at UCLA and his team which include Vinton Cerf, Steve Crocker, Bill Naylor, Jon Postel, and Mike Wingfield connected one of the center's SDS Sigma 7 computers to an Interface Message Processor ([[IMP]]). The team from UCLA were able to successfully exchange the message "Do it to it, Truett" with BBN hardware designer Ben Barker. On that day, ARPANET/Internet was born.<ref>[http://www.livinginternet.com/i/ii_arpanet.htm ARPANET-The First Internet]</ref>

The second node connected to the ARPANET was the NLS System (on-Line System) developed by [[Douglas Engelbart]].<ref>[http://www.livinginternet.com/w/wi_engelbart.htm Douglas Engelbart]</ref> He invented the mouse, graphical user interface and the hypertext linking system which are key components of the modern computer.<ref>[http://unrev.stanford.edu/ Engelbart's Unfinished Revolutions]</ref>

The second node connected to the ARPANET was the NLS System (on-Line System) at the SRI which was developed by [[Douglas Engelbart]].<ref>[http://www.livinginternet.com/w/wi_engelbart.htm Douglas Engelbart]</ref> This was the first full ARPANET network connection using an SDS-940 computer with the Genie Operating System and a 50 kbps line from [[AT&T]]. However, the first test did not work properly and the system crashed. The second test worked fine according to Kleinrock.

 

The third connection added to the ARPANET was an IBM 360/75 computer using the OS/MVT operating system from the [[Culler-Fried Interactive Mathematics Centre]] at the University of California at Santa Barbara followed by the DED PDP-q0 computer using a Tenex Operatin System from University of Utah Graphix Department. The first four nodes connected to the ARPANET became operational. From the beginnings of ARPANET, the development and growth of the internet increased rapidly.<ref>[http://www.livinginternet.com/i/ii_arpanet.htm ARPANET-The First Internet]</ref>
