Turing Machine

A Turing machine is a theoretical computing device invented by Alan Turing to understand the limits of what can be computed. It consists of a tape divided into squares that can hold symbols, a read/write head that moves along the tape, and a set of rules that dictate how to read and write based on the current symbol. This model helps in exploring fundamental concepts of computation, algorithms, and complexity, illustrating how problems can be solved or whether they can be solved at all. It is a foundational concept in computer science and mathematics.
