What is the function of the Control Unit (CU) in a computer system ?
Answer: C
The Control Unit manages and coordinates the execution of instructions.
The CU fetches each instruction, decodes it and generates the control signals that tell the ALU, registers, memory and input/output devices what to do and when. It directs the work but does not itself compute.
The actual arithmetic and logic is done by the ALU, data is stored in memory, and input/output is handled by I/O devices under the CU's direction.
