    Question

    In computer architecture, what is the role of the

    control unit in a CPU?
    A Executes arithmetic operations Correct Answer Incorrect Answer
    B Manages data transfer between memory and CPU Correct Answer Incorrect Answer
    C Stores instructions temporarily Correct Answer Incorrect Answer
    D Directs the operation of the processor Correct Answer Incorrect Answer
    E Increases clock speed dynamically Correct Answer Incorrect Answer

    Solution

    The control unit of a CPU is responsible for directing the operation of the processor. It interprets instructions from memory and controls the sequence of execution by signaling the appropriate parts of the CPU to carry out instructions. Why Other Options are Wrong: a) The ALU (Arithmetic Logic Unit) performs arithmetic operations. b) Data transfer between memory and CPU is handled by the memory unit. c) Instructions are stored in registers, not managed directly by the control unit. e) Clock speed is controlled by external hardware, not by the control unit.
