The Central Processing Unit (CPU) is the computer's computing and control core.

According to the HCIA–Cloud Computing curriculum underServer Basics, the CPU is defined as thecore component responsible for computation and controlwithin a computer system. The CPU executes program instructions and coordinates the operation of all other hardware components.

The CPU is primarily composed of two main functional units:

Arithmetic Logic Unit (ALU):Responsible for performing arithmetic operations (such as addition and subtraction) and logical operations (such as comparisons and logical AND/OR).

Control Unit (Controller):Responsible for fetching instructions from memory, decoding them, and controlling the execution process by issuing control signals to other components.

The CPU operates based on thefetch–decode–execute cycle, which is a fundamental concept emphasized in HCIA learning materials. During this process, the CPU reads instructions and related data from memory, processes them, and produces results according to the instruction set architecture.

Because the statement accurately describes therole, composition, and working principleof the CPU as defined in Huawei’s HCIA–Cloud Computing documentation, it iscorrect.
