Which term refers to the central processing unit?

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

Answer: (A)

The CPU is the brain of the computer. It fetches instructions, decodes what they mean, and executes them, performing calculations and coordinating data flow between memory and other parts of the system. ROM, or read-only memory, stores fixed data and instructions that don’t change; RAM, or random-access memory, provides fast, temporary storage for data the CPU is actively using and is volatile, meaning it loses its contents when power is off. Peripheral devices are external components like a keyboard, mouse, or printer that connect to the computer and rely on the CPU to process data. Because the term that specifically refers to the central processing unit is CPU.
