#What is the relationship between CPU memory and hard disk?

There is a cooperative relationship between the CPU memory and the hard disk. The CPU memory is responsible for the data exchange processing between the data on the hard disk and other hardware and the CPU. It has the characteristics of small size, fast speed, and can be stored with electricity. The hard disk is a device that stores data such as information and software. It has the characteristics of large capacity and no data loss when power is turned off.

Function of CPU

1. Processing instructions: This refers to the execution sequence of instructions in the control program. There is a strict sequence between the instructions in the program, and they must be executed strictly in the order specified by the program to ensure the correctness of the computer system.

2. Execution of operations: The function of an instruction is often implemented by a series of operations performed by components in the computer. The CPU must generate corresponding operation control signals according to the function of the instruction and send them to the corresponding components, thereby controlling these components to act according to the requirements of the instruction.

3. Control time: Implement time timing for various operations. During the execution of an instruction, what operations are performed at what time should be strictly controlled so that the computer can work in an orderly manner.
