The Turing machine. He formulated played an important role in the creation of the modern-day computer, Turing machine is a device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.According to wikipedia
According to wikipedia During World War II, he worked to decipher Nazi codes, he was the director of the Naval Enigma section of Bletchley Park. After the war he designed one of the first programmable electronic digital computers in the National Physical Laboratory in the UK and after built his first machines at the University of Manchester Called the Manchester Computer
