A Turing machine is a mathematical model of computation that defines an abstract machine, which manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, given any computer algorithm, a Turing machine capable of simulating that algorithm's logic can be constructed. The machine operates on an infinite memory tape divided into discrete"cells". The machine positions its "head" over a cell and "reads" or "scans" the symbol there. Then, as per the symbol and its present pla

Turing Machine: A Turing machine is a theoretical machine that manipulates symbols on a tape strip, based on a table of rules. Even though the Turing machine is simple, it can be tailored to replicate the logic associated with any computer algorithm. It is also particularly useful for describing the CPU functions within a computer. Alan Turing
