What best describes the role of the control unit in the CPU?

The control unit (CU) plays a crucial role in the CPU by coordinating and directing the operations of the various components within the processor. It orchestrates the execution of instructions by managing the flow of data between the CPU, memory, and input/output devices. The control unit interprets instructions from programs, generating control signals that determine how and when data is processed and transferred. It effectively acts as the central point of communication, ensuring that all parts of the CPU work together in an organized and efficient manner. This role is vital for the proper execution of programs, making option B the most accurate description of the function of the control unit.
