The CPU of a microcomputer is a:

• A. ALU
• B. Microcontroller
• C. Microprocessor
• D. Printed circuit assembly

Answer: (C)

The CPU in a microcomputer is the microprocessor. The central processing unit is the part that fetches, decodes, and executes instructions and coordinates data flow inside the system. In most microcomputers this role is implemented as a microprocessor—a single integrated circuit that contains the core CPU components. The ALU (arithmetic logic unit) is a piece inside the processor that handles math and logical operations. A microcontroller, while it does include a CPU, is a complete small computer on a chip with its own memory and I/O peripherals, used for dedicated tasks. A printed circuit assembly is the physical board that hosts components, not the processor itself.
