some Information about internet


Roads and Crossroads of the Internet History
Information Age Milestones 
1866:" In the beginning was the Cable..."

The Atlantic cable of 1858 was established to carry instantaneous communications across the ocean for the first time.
The manufacture of the cable started in early 1857 and was completed in June. Before the end of July it was stowed on the American "Niagara" and the British "Agamemnon" -- both naval vessels lent by their respective governments for the task.
Although the laying of this first cable was seen as a landmark event in society, it was a technical failure. It only remained in service a few days. Subsequent cables laid in 1866 were completely successful and compare to events like the moon landing of a century later... the cable ... remained in use for almost 100 years.

1957: Sputnik has launched ARPA  
President Dwight D. Eisenhower saw the need for the Advanced Research Projects Agency (ARPA) after the Soviet Union's launch of Sputnik.

1957 - October 4th - the USSR launches Sputnik, the first artificial earth satellite:


    1958 - February 7th - In response to the launch of Sputnik, the US Department of Defense issues directive 5105.15 establishing the Advanced Research Projects Agency (ARPA).
    The organization united some of America's most brilliant people, who developed the United States' first successful satellite in 18 months. Several years later ARPA began to focus on computer networking and communications technology.
    In 1962, Dr. J.C.R. Licklider was chosen to head ARPA's research in improving the military's use of computer technology. Licklider was a visionary who sought to make the government's use of computers more interactive. To quickly expand technology, Licklider saw the need to move ARPA's contracts from the private sector to universities and laid the foundations for what would become the ARPANET.
    The Atlantic cable of 1858 and Sputnik of 1957 were two basic  milestone of the Internet prehistory. You might want also to take a look on  the Telecommunications and Computers preHistory
    According toVinton Cerf:
    ...the UCLA people proposed to DARPA to organize and run a Network Measurement Center for the ARPANET project...
    Around Labor Day in 1969, BBN delivered an Interface Message Processor (IMP) to UCLA that was based on a Honeywell DDP 516, and when they turned it on, it just started running. It was hooked by 50 Kbps circuits to two other sites (SRI and UCSB) in the four-node network: UCLA, Stanford Research Institute (SRI), UC Santa Barbara (UCSB), and the University of Utah in Salt Lake City.
