Which component of the CPU controls the flow of data within the computer?

The control unit is responsible for directing the operation of the processor and controlling the flow of data within the computer. It interprets instructions from memory, tells the ALU (Arithmetic Logic Unit) what operations to perform, and manages the movement of data between the CPU and other hardware components, such as memory and input/output devices. By issuing control signals, the control unit orchestrates operations that allow different parts of the computer to communicate and work together effectively.

The ALU focuses specifically on performing arithmetic and logical operations, rather than controlling the data flow. The arithmetic register is used for temporarily holding data that is to be processed but doesn't control flows. The memory data register is involved in holding data that is being transferred to or from memory, but it does not govern the overall operation of data within the computer. Thus, the control unit distinctly serves as the central unit that manages and regulates the movement and processing of data throughout the system.
