Which term describes a CPU implemented on a single integrated circuit?

• A. Central Processing Unit
• B. Integrated Circuit
• C. Microprocessor
• D. Processor

Answer: (C)

The main idea here is knowing what term names a CPU that is built on one chip. A microprocessor is a CPU implemented on a single integrated circuit, packing the processing unit, control logic, and registers onto one chip. An integrated circuit is the general technology used to make a chip, but it doesn’t itself specify that it’s a CPU. A central processing unit describes the computing core, but it doesn’t say how it’s packaged or built. A processor is a broad word for the component that executes instructions, not necessarily one chip. So the description that fits a CPU on one IC best is microprocessor, since it explicitly captures the on-a-chip, single-chip implementation.
