Control Unit and motherboard

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. A CU component is considered the processor brain because it issues orders to just about everything and ensures correct instruction execution.
