The control unit triggers the arithmetic operations in the ALU.

How does the control unit know to request an addition or a subtraction? The answer is: it obtains instructions, one at a time, that have been stored in primary storage.

Like an orchestra leader, the control unit does not execute program instructions; rather, it directs other parts of the system to do so.
