Celebrating the birthplace of the Internet in pictures

  • 1 of 13

Nov. 21 marks the 42nd anniversary of the first permanent Advanced Research Projects Agency Network (ARPANET) link between UCLA's Interface Message Processor (IMP) and the IMP at the Stanford Research Institute . By Dec. 5, 1969, the original four-node ARPANET environment was set up. History notes this network as the world's first operational packet switching network and the core of what is today’s Internet. UCLA recently opened the Kleinrock Internet Heritage Site and Archive in honor of the ARPANET project’s overseer Professor Leonard Kleinrock, to preserve and celebrate the birthplace of the Internet. The first message between the nodes had been sent by Kleinrock on Oct. 29, 1969.
