This machine was also one of the first true computing machines, and its level of logical simplicity and mechanical complexity are evidence of Turing's supreme genius in this area (Ellsbury). Not only did this machine revolutionize cryptography, which in itself made a giant contribution to the world of computer science, it also provided a great deal of information that was used by the Allies in order to win the war (Wikiepedia; Ellsbury). The Bombe in and of itself, however, does not constitute Turing's single greatest achievement in the world of computer science or logic. This honor, without a doubt, belongs to the Turing Machine, which is not actually a mechanical device at all, or even a single machine (Hodges (a)). The Turing Machine is actually a description of infinitely man theoretical machines, which could be built to carry out a specified series of operation based on the reading, erasing, and printing of a paper strip. The machine would read information from the paper strip, and use this information to advance the strip and...

This theoretical device is essentially how a modern computer or computer program works, on different hierarchies.
