What does a von Neumann model computer include?

The Von Neumann model computer includes arithmetic units, controllers, memories, input devices, and output devices; the Von Neumann structure, also known as the Princeton structure, is a type of computer that combines program instruction memory and data memory. memory structure together.

Operator, controller, memory, input device, output device.

A computer must have five basic components, including:

1: Input device for inputting data and programs;

2: Memory for storing programs and data;

3: The arithmetic unit that completes data processing;

4: The controller that controls program execution;

5: The output device that outputs the processing results.

The von Neumann structure, also known as the Princeton structure, is a memory structure that combines program instruction memory and data memory. The program instruction storage address and the data storage address point to different physical locations in the same memory, so the width of the program instructions and data are the same. For example, the program instructions and data of Intel's 8086 central processor are both 16 bits wide.

The mathematician von Neumann proposed three basic principles for computer manufacturing, namely the use of binary logic, program storage and execution, and the computer is composed of five parts (operator, controller, memory, input device, output device), this theory is called the von Neumann architecture.
