Which component executes instructions and manages data processing?

• A. PERIPHERAL DEVICES
• B. RAM
• C. ROM
• D. CPU

Answer: (D)

Executing instructions and managing data processing is done by the central processing unit, the brain of the computer. The CPU runs the fetch-decode-execute cycle, pulling instructions from memory, figuring out what action is required, and performing the necessary operations, such as arithmetic, logic, or moving data around. It coordinates data flow and control signals, directing how memory and I/O devices work together to complete tasks. Peripheral devices are mainly for input, output, or communication with the outside world and don’t perform the core processing. RAM provides fast, temporary storage for data and instructions the CPU uses while programs run, but it doesn’t execute instructions itself. ROM stores essential firmware and permanent instructions used during boot and basic operations, not general processing. So the component that handles instruction execution and data processing is the CPU.
