What is the main contribution of the Turing machine computational model?

The main contributions of the Turing machine computing model are: 1. It proves the universal computing theory and affirms the possibility of computer implementation. At the same time, it gives the main architecture that a computer should have; 2. It introduces reading and writing The concepts of algorithms and programming languages ​​have greatly broken through the design concepts of computing machines in the past.

The main contributions of the Turing machine computing model to modern computers are: establishing the theoretical model of the Turing machine and laying the foundation for the "computability" theory. Basics; proposed the Turing test and elaborated on the concept of machine intelligence.

The so-called Turing machine refers to an abstract machine. It has an infinitely long paper tape. The paper tape is divided into small squares, each square has a different color. There is a machine head that moves around on the paper tape. The machine head has a set of internal states, as well as some fixed procedures. At each moment, the machine head must read a square of information from the current paper tape, then search the program table based on its own internal state, output the information to the paper tape square according to the program, and convert its own internal state, and then Make a move.

The significance of the Turing machine:

• It proves the universal computing theory and affirms the possibility of computer implementation. At the same time, it gives the main architecture that a computer should have;

• The Turing machine model introduces the concepts of reading and writing, algorithms and programming languages, which greatly breaks through the past design concepts of computing machines;

The Turing machine model theory is the core theory of the computing discipline, because the ultimate computing power of a computer is the computing power of a universal Turing machine. Many problems can be transformed into the simple model of the Turing machine for consideration.

The universal Turing machine shows people such a process: the program and its input can be saved on the storage tape first, and the Turing machine runs the program step by step until the result is given, and the result is also saved on the storage tape. More importantly, we can vaguely see the main components of modern computers, especially the main components of von Neumann's theory.
