Which of the following unit(s) is/are part(s) of a CPU ?
Explanation
The Central Processing Unit (CPU) is the primary component of a computer system responsible for executing instructions. It traditionally consists of three main functional components:
- Arithmetic Logic Unit (ALU): This unit performs all arithmetic calculations (such as addition and subtraction) and logical operations (such as comparisons).
- Control Unit (CU): It acts as the supervisor of the system, controlling the flow of data and instructions between the CPU, memory, and input/output devices.
- Memory Unit (Registers/Cache): While main memory (RAM) is external to the CPU, the CPU contains internal high-speed storage locations known as registers (and often cache) used to store immediate data and instructions during processing.
In standard functional block diagrams of computer architecture, these three units together constitute the CPU. Therefore, option D is the most comprehensive and correct choice.
