===The ARPANET was born===

The realization of the vision of Licklider for the ARPANET as a universal communication network became evident on September 1969 when NWG member Leonard Kleinrock, head of the Network Measurement Center ([[NMC]]) at UCLA and his team which include [[Vinton Cerf]], [[Stephen  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) 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.<ref>[http://www.livinginternet.com/i/ii_arpanet.htm ARPANET-The First Internet]</ref>
