The Turing machine is an abstract machine introduced in 1936 by Alan Turing to give a mathematically precise definition of algorithm or 'mechanical procedure'.The concept is still widely used in theoretical computer science, especially in complexity theory and the theory of computation. Turing machine that is able to simulate any other Turing machine is called a universal Turing machine or simply a universal machine as Turing described it in 1947: It can be shown that a single special machine of that type can be made to do the work of all.
