If the military invented the internet then what did Vinton Cerf do?
Cerf and Robert Kahn invented the Internet Protocol, and the Transmission Control Protocol, together known as TCP/IP. At that time, they both worked for the US Department of Defense.
The rest of this answer is about IP addressing and packet transmission, in case you were wondering.
Think of an IP address like a mailbox for every computer and website online.
When your computer sends out a message, it is broken up from one "letter" into many smaller "postcards" all headed for the same "mailbox" associated with another computer or website that you're sending to. Those "postcards" -- called packets -- may take 1,000 different routes to arrive at the destination where they are reassembled into your original message again.
Basically, before packets and IP addresses, there was just one computer or computer terminal "talking" to another over a dedicated connection -- think of that like a telephone without call waiting; just one on one. With routing, the packets can jump onto the "Information Superhighway" and take the most convenient route to get to a destination, flowing right along with other packets from other people, sharing circuit resources, until they get to where they're going.
(Yes, fellow nerds, I realize I simplified that like a crazy woman:)
Answer Time Berniers Lee did not invent the internet. The internet was invented in 1969 by for the U.S. Department of Defense's ARPANET. Likewise, Robert Kahn and Vinton Cerf invented TCP/Internet Protocol in 1983. Tim Berniers Lee merely built upon what the forefathers of the internet had already accomplished, thus Berniers Lee is accredited with inventing the World Wide Web in 1989.
Robert k Haen does not garner any search results. However, Dr. Robert Khan is a well-respected and oft-awarded member of the internet hall of fame. In December 1997, Dr. Kahn and his colleague, Vinton Cerf, were awarded the U.S. National Medal of Technology by the President of the United States. Kahn and Cerf received the medal for founding and developing the Internet.
Original Answer: CERN, about 1980 Others: Philip Emeagwali Vinton Gray Cerf Tim Berners Lee The connection of many computers having linked data was originally a US military idea, so people such as Berners Lee competed to create a working, linked system (incase one base was attacked, the data would still exist)
