With the development of modern society and science and technology, there is a stronger demand for new computing tools. In the history of computer development, the Turing machine model, the first computer, and the Von Neumann machine model are three important events in the process of computer emergence. 3/24/2023 1.1.1 Turing Machine Model In 1936, the famous mathematician Turing of Cambridge University in the UK published a paper on the "ideal computer" while studying the basic theoretical problem of mathematics. In this paper, he proposed a mathematical model of a modern universal digital computer. This theoretical machine is called the Turing machine. Turing analyzed and proved this type of machine in the paper. ".
