It tells the ALU what operation to perform based on the instructions from the program.

Explanation

The CPU (Central Processing Unit) includes:

1. ALU (Arithmetic Logic Unit)
2. CU (Control Unit)
3. Registers (temporary storage inside CPU)

Primary Storage (like RAM) is not part of the CPU; it is part of the main memory.
