A Turing machine is a theoretical computing device that consists of an infinitely long tape divided into cells, a read/write head that can move along the tape, and a control unit that determines the machine's behavior. It is capable of performing various operations such as reading and writing symbols on the tape, moving the head left or right, and changing its internal state based on a set of predefined rules. Turing machines are used to study the limits of computation and are considered a fundamental concept in the theory of computation.
