Answer:

Correct Answer: D

Solution:

  • The control unit is the component of the processor that directs and co-ordinates most of the operations in the computer. It is the circuitry that control the How of information through the processor and co-ordinates the activities of the other units: within it. In a way, it is the “brain within the brain”, as it controls what happens inside the processor (CPU), which in turn controls the rest of the PC.
