The CPU is the brain of a computer, where it “fetches each program instruction from memory and carries out and executes the instruction”.
On a technical level the top three components of a CPU are:
1. Arithmetic Logic Unit (ALU):
The arithmetic logic unit performs logical operations such as multiples, division, addition, subtraction, and also determines the number is positive or negative integer or zero. These operations are performed in a sequence order, based on the given instructions from the control unit.

The CPUs control unit is a key component which is responsible for executing or maintaining the results coming out of the logical unit. With the CPU, it works and compiles, executes or fetch the given data by the input. The control unit responds and communicates with both the internal arithmetic logical unit and storage memory, and which completely directs the computer system to carry out, or execute, stored program signals or instructions. …show more content…
Registers:
Registers are the temporary storage locations. CPU instructions operates on these instructions or data within the processor. A register may hold a computer cache memory which said to be RAM where processor can access data faster and helps in preventing time-consuming.
