Why is the CPU called the "brain" of the computer rather than the hard drive or RAM?

ABecause it processes instructions and controls operations

BBecause it stores all data permanently

CBecause it displays images on the screen

DBecause it supplies power to the computer

Step-by-Step Solution

Solution:

Step 1: Understand CPU's role
The CPU processes instructions and controls the computer's operations, similar to how a brain controls a body.
Step 2: Compare with other components
Hard drive stores data, RAM holds temporary data, but neither controls or processes instructions like the CPU.
Final Answer:
Because it processes instructions and controls operations -> Option A
Quick Check:
CPU = Brain due to control and processing [OK]

Quick Trick: CPU controls and processes, others store or display [OK]
