Not that it matters, but Cicso wasn't founded until 1984, and didn't ship it's first product, a network router, until 1986. Cisco played no role in the early development of the military's computer technology. In response to Sputnik in 1957 (the greatest year ever because it was the year of the '57 Chevy, and me), ARPA (Advanced Research Projects Agency) was formed in 1958 as a Department of Defense agency tasked with never letting a technological surprise like Sputnik happen again, and furthermore, to ensure that the US military's technology stays superior to that of any of our enemies or potential enemies. The name was changed to DARPA (D for Defense), then back to ARPA, and now I think it's back to DARPA again. But it's all the same thing.
Military research and development into computer technology has always been a close relationship with universities. The first published dream of having a widespread and wide-band telecommunications system came in 1960 out of ARPA. The dream became an actrual need 2 years later when research terminals were set up at a company in Santa Monica, one at Berkeley, and one at MIT, and the ARPA Director of Information Processing (where all the really kewl research was done) got frustrated by having to use a different terminal to communicate with each location, rather than being able to use just the one terminal to communicate with everybody all at once.
This led Paul Baran of the Rand Corporation and Leonard Kleinrock of MIT to develop an idea put forth by Donald Davies of the UK's National Physical Laboratory of packet-switching, where data was sent via small packets, with redundant information and individual packet routing information contained within each packet. This eliminated single-point data failures and enabled packets to be sent from one terminal to any number of other terminals. ARPA, now DARPA, brought in MIT, UCLA and Stanford and created the first packet-switching network, called ARPANET, in 1969, and for all intents and purposes, that's the birth of the Internet right there. The University of Utah and UC Santa Barbara were quickly added, and after that a new host was added on an average of every 20 days to where by 1981 there were more than 200 network nodes. ARPANET was the technical core of what would become the Internet, as everything the Internet is today is still based on that core.
Uhm, Mr Peabody is a fictional dog, and an insufferable genius. I am neither a fictional dog nor a genius. I'm merely insufferable.
I also do not have a pet boy.
