Unit V: Control Unit - Computer Architecture

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 on how to respond to a program's instructions. It controls on primitive operations (micro-operations).
