Detailed explanation-1: -The arithmetic logic unit (ALU) performs mathematical calculations; it is the part that computes.
Detailed explanation-2: -An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).
Detailed explanation-3: -The control unit tells the ALU what operation to perform on that data, and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.
Detailed explanation-4: -ALU stands for Arithmetic and Logical Unit which performs Arithmetic functions like Addition, subtraction, division, etc. CU stands for control unit which performs the task of controlling functions of the computer. It monitors and gives proper instructions to all parts of the computer.
