The 3 parts of the CPU are

Central Processing Unit

Arithmitic Logic Unit

Control Unit

The three components of a CPU are:

1. Arithmetic Logic Unit (ALU)

The ALU is the part of a CPU that performs all arithmetic computations including addition, subtraction, multiplication, and division.

2. Control Unit

The CPUs control unit is responsible for executing or storing the results coming out of the ALU. Within the CPU, the control unit performs the functions of fetch, decode, execute, and store.

3. Registers

Registers work under the direction of the control unit to accept, hold and transfer instructions or data and perform arithmetic or logical comparisons at a high rate of speed.
