Because it can "store programs". Stored program is the basis for computer automatic control processing. Its principle is to store a program written according to a specific problem in the computer memory, and then execute the first instruction of the program according to the first address of the stored program in the memory, and then follow the program in the future. Execute other instructions in the specified order until the program ends.

Computers can perform automatic control processing because they can "store programs."

The principle of "stored program" is to store a program written according to a specific problem in the computer memory, and then execute the first instruction of the program according to the first address of the stored program in the memory, and then follow the The program executes other instructions in the specified sequence until the program ends.

Stored programs are the basis for computers to automatically control processing.

The computer system consists of two major parts: hardware system and software system. The Von Neumann structure (John von Neumann), that is, the stored program, laid the basic structure of modern computers. Its characteristics are:

1) Use a single processing unit to complete calculation, storage and communication work.

2) The storage unit is a fixed-length linear organization.

3) The units of storage space are directly addressable.

4) Using low-level machine language, instructions complete simple operations through opcodes.

5) Centralized sequence control over calculations.

6) The computer hardware system consists of five major components: arithmetic unit, memory, controller, input device, and output device and stipulates their basic functions.

7) Use binary form to represent data and instructions.

8) When executing programs and processing data, the programs and data must be loaded from the external memory into the main memory, and then the computer can automatically adjust the instructions to be fetched from the memory and executed during operation.
