First demonstration of remote computingIn 1940, the first demonstration of remote computing took place when a teletype terminal at the American Mathematical Association Meeting in Dartmouth, New Hampshire was used to communicate over phone lines with an attendant at the keyboard for input to George Stibitz's Complex Number Calculator in New York. The machine had been operational since 1 Aug 1940. In 1940, George Stibitz's Complex Number Calculator was functional. He was a research mathematician at Bell Laboratories, who worked on its construction from Apr 1939, assisted by Samuel Williams. Later known as Bell Labs Model I Relay Computer, it used telephone relays and coded decimal numbers as groups of four binary digits (bits) each. It has been called the first electromechanical computer for routine use.«[Image: An attendant sends messages to the Model I relay computer.] |
