The Central Processing Unit (CPU) is also known as what?

• A. The Processor
• B. Main Memory
• C. The Motherboard
• D. Expansion Card

Answer: (A)

Think of the CPU as the brain of the computer—the part that fetches, decodes, and executes instructions. Because of that role, it’s widely known as the processor, a term that emphasizes its function of processing operations inside the machine. Main Memory refers to RAM, where data and instructions are stored temporarily; the Motherboard is the main circuit board that connects all components; an Expansion Card is a plug-in device that adds new capabilities. So the term that best describes the CPU is the processor.
