What is the primary function of the Control Unit (CU) in a CPU?

Solution (By Examveda Team)

Option B: Directs operations of the entire computer system
The primary function of the Control Unit (CU) in a CPU is to direct and coordinate the operations of the entire computer system. It manages the execution of instructions by fetching them from memory, decoding them, and controlling the data flow between the CPU and other parts of the computer system, including RAM, I/O devices, and the ALU (Arithmetic Logic Unit). The CU also manages the timing and control signals necessary for communication between these components.

Option A: Executes program instructions
While the CPU as a whole executes program instructions, specifically, it is the combination of the Control Unit (CU) and the Arithmetic Logic Unit (ALU) that executes the instructions. The CU directs this process.

Option C: Stores data temporarily
This role is typically associated with memory units such as RAM (Random Access Memory) rather than the Control Unit (CU), which primarily handles control and coordination tasks.

Conclusion:
The correct answer, Option B: Directs operations of the entire computer system, best describes the primary role of the Control Unit (CU) in a CPU, emphasizing its critical function in managing and coordinating the operation of the entire computer system.
