Which statement defines the processor?

• A. A device that stores data permanently.
• B. The component of a computer that follows instructions and interprets them.
• C. An input device.
• D. The cooling system.

Answer: (B)

The processor, or central processing unit, is the part of a computer that follows instructions and carries them out. It fetches instructions from memory, decodes what each instruction means, and then executes the required operations. This fetch-decode-execute cycle, handled by the control unit and the arithmetic logic unit, is what lets programs run and respond to data. The processor’s role is to interpret instructions and perform calculations, data movement, and decision making as directed by the software. Other options point to different functions: one describes long-term data storage, another is an input device, and another is a cooling system. These are important parts of a computer too, but they don’t define what the processor does.
