Detailed explanation-1: -What is an arithmetic-logic unit (ALU)? 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-2: -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.
Detailed explanation-3: -The arithmetic logic unit (ALU) performs mathematical calculations; it is the part that computes.
Detailed explanation-4: -The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data.
Detailed explanation-5: -The arithmetic and logic unit (ALU) is where the CPU performs the arithmetic and logic operations. Examples of arithmetic operations are addition, subtraction, multiplication, and division.
