What is a Turing Machine? By Jack Copeland. ©Copyright B.J. Copeland, July 2000. In 1935, at Cambridge University, the British logician and computer pioneer Alan Mathison Turing conceived the modern computer. He described an abstract computing machine consisting of a limitless memory and a scanner that moves back and forth through the memory, symbol by symbol, reading what it finds and writing further symbols. The actions of the scanner are dictated by a program of instructions that is also stored in the memory in the form of symbols. This is Turing's stored-program concept, and implicit in it is the possibility of the machine operating on, and so modifying or improving, its own program. Turing's computing machine of 1935 is now known simply as the universal Turing machine. All modern computers are in essence universal Turing machines.
