The central processor of a computer is comprised of___________________?
Show answer Hide answer
Answer: D. Control Unit and ALU
Explanation
The central processor of a computer comprises the control unit and ALU. The control unit directs operations while the ALU performs mathematical calculations. Together these two components form the core intelligence of the processor chip. The control unit fetches instructions from memory and decodes their operational meaning. Registers inside the CPU hold temporary data needed for immediate execution. Microprocessors integrate these subunits onto a single tiny piece of silicon.
CPU architecture designs focus on optimizing the interaction between control and ALU units. Understanding processor internals helps computer science students write efficient algorithms. Hardware engineers miniaturize these components to build faster mobile processors. CPU and main memory together form the computer system rather than just the processor. Hard disks and floppy drives are secondary storage peripherals outside the CPU. Main memory and storage refer to RAM and disk drives rather than processor subunits.
