2.2f) Why is CPU called the brain of a computer?

The CPU is called the "brain of the computer" because it is responsible for processing all instructions and controlling the operations of the system, similar to how a brain controls a human body.

Reasons Why CPU is the Brain of a Computer:

1. Processes Instructions: It executes commands from software and hardware, enabling the computer to perform tasks.
2. Performs Calculations: It handles arithmetic and logic operations essential for decision-making and problem-solving.
3. Controls Other Components: It directs and coordinates the actions of all other hardware components.
4. Data Management: It fetches, decodes, and executes instructions, managing the flow of data within the system.

Without the CPU, a computer cannot function, just as the human body cannot operate without a brain.
