The Purdy Polynomial hash algorithm was developed for the ARPANET to protect passwords in 1971 at the request of Larry Roberts, head of ARPA at that time. It computed a polynomial of degree 2 24 + 17 modulo the 64-bit prime p = 2 64 − 59.
Larry Roberts (December 21, 1937 – December 26, 2018) was an American computer scientist and Internet pioneer.. As a program manager and later office director at the Advanced Research Projects Agency, Roberts and his team created the ARPANET using packet switching techniques invented by British computer scientist Donald Davies and American engineer Paul Baran.
Leonard Kleinrock was born in New York City on June 13, 1934, to a Jewish family, [3] and graduated from the noted Bronx High School of Science in 1951. He received a Bachelor of Electrical Engineering degree in 1957 from the City College of New York, and a master's degree and a doctorate (Ph.D.) in electrical engineering and computer science from the Massachusetts Institute of Technology (MIT ...
The ARPAnet -- the precursor to the Internet -- came from the Defense Advanced Research Projects Agency, better known as DARPA. The transformative invention is just one of many DARPA projects that ...
He wrote a file transfer program called CPYNET to transfer files through the ARPANET. [19] Tomlinson was asked to change a program called SNDMSG, which sent messages to other users of a time-sharing computer, to run on TENEX. [20] He added code he took from CPYNET to SNDMSG so messages could be sent to users on other computers—the first email ...
[10] [11] In the fall of 1972, he demonstrated the ARPANET by connecting 20 different computers at the International Conference on Computer Communications (ICCC), "the watershed event that made people suddenly realize that packet switching was a real technology." [12] In 1972, he joined the Information Processing Techniques Office (IPTO) within ...
Joseph Carl Robnett Licklider (/ ˈ l ɪ k l aɪ d ər /; March 11, 1915 – June 26, 1990), known simply as J. C. R. or "Lick", was an American psychologist [3] and computer scientist who is considered to be among the most prominent figures in computer science development and general computing history.
Cisco Systems was founded on Dec. 10, 1984, by Sandy Lerner and Len Bosack, who had developed a groundbreaking new connectivity device called a router while working on Stanford University's computer
