Answer:
The CPU processes instructions it receives in the process of decoding data.
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU). While the memory unit (MU), is the primary memory for holding data. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
