Answer 1

Answer:

CPU ( central processing unit)

Answer 2

Answer:

The BIOS performs most of the calculations which enable a computer to function and is sometimes referred to as the "brain of the computer" - CPU.

Explanation:

• The CPU, which houses all the circuitry required to process input, store data, and output results, is the brain of a computer.
• The CPU is constantly executing computer programs that give it instructions on which data to process and in what order.
• We couldn't use a computer to run the program without a CPU.
• Thanks to a control unit that can understand program instructions and an Arithmetic Logic Unit (ALU) that can add numbers, the CPU can process those instructions with ease.
• The CPU can process far more sophisticated programs than a simple calculator thanks to the control unit and ALU working together.

CPU itself has the following three components.

• Memory or Storage Unit
• Control Unit
• ALU(Arithmetic Logic Unit)

• Memory or Storage Unit: This component has storage space for instructions, data, and interim outcomes. When necessary, this device provides data to the computer's other components. It is sometimes referred to as an internal storage device, primary memory, or random access memory (RAM).
• Control Unit: While all of the computer's components are controlled by this unit, no actual data processing is done by it.
• Arithmetic Logic Unit: There are two subsections in this unit:
• Arithmetic Section
• Logic Section
• Arithmetic Section: The addition, subtraction, multiplication, and division operations are carried out in the arithmetic area. The above operations are used repeatedly to complete all complex operations.
• Logic section: The purpose of the logic section is to carry out logic operations on the data, including comparison, selection, matching, and merging.
