WebA turing machine is a mathematical model of a computation that defines an abstract machine. Despite its simplicity, given any algorithm, this machine is capable of implementing the algorithm's logic. The Church-Turing thesis states that every computational process that is said to be an algorithm can be implemented by a turing machine. References.
