Turing Machine

A Turing machine is a mathematical model of computation that defines an abstract machine[1] that manipulates symbols on a strip of tape according to a table of rules.[2] Despite the model's simplicity, given any computer algorithm, a Turing machine capable of implementing that algorithm's logic can be constructed... The Turing machine was invented in 1936 by Alan Turing,[11][12] who called it an "a-machine" (automatic machine). https://en.wikipedia.org/wiki/Turing_machine
