Option 1 : Control unit

  • The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor.
  • It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
  • It directs the operation of the other units by providing timing and control signals. Most computer resources are managed by the CU.
  • It directs the flow of data between the CPU and the other devices.
  • John von Neumann included the control unit as part of the von Neumann architecture.
  • In modern computer designs, the control unit is typically an internal part of the CPU with its overall role and operation unchanged since its introduction.
