What was the name of the first stored-program computer designed by Turing?
Answer
Automatic Computing Engine
Answer
Automatic Computing Engine
The first stored-program computer designed by Alan Turing was the Automatic Computing Engine, usually abbreviated ACE. Turing designed it after joining the National Physical Laboratory in Britain in 1945, where he prepared a detailed report called “Proposed Electronic Calculator.”
The ACE project was influenced by Turing’s theoretical work on universal computation and by his wartime experience with electronic machines. His original design was ambitious and was not built in its complete form. Instead, engineers at the NPL constructed a smaller version called the Pilot ACE, which ran its first program on 10 May 1950.
ACE is often confused with ENIAC, EDSAC, and the Manchester Mark 1 because all were pioneering early computers. ENIAC was an American electronic computer, while EDSAC and the Manchester Mark 1 were British stored-program machines developed by different teams. The Pilot ACE was one of the earliest general-purpose stored-program computers, but the answer to the question asks for Turing’s design: the Automatic Computing Engine.
