A processor that consists of one control unit and one ALU is called a ________.

A processor that consists of one control unit and one ALU is called a ________.

• A. Single-core processor
• B. Dual-core processor
• C. Multi-core processor
• D. Pipeline processor

Answer: (A)

The key idea is that a processor's core is a single processing unit that includes its own control logic and an arithmetic-logic unit (ALU). If there is only one such core in the chip, the processor is a single-core processor. A dual-core or multi-core processor has two or more cores, each capable of handling its own instructions. A pipeline processor describes how instructions are processed in stages to improve throughput, which is about technique rather than the number of cores. Since this processor has just one control unit and one ALU, it has a single processing core, so the correct term is a single-core processor.
