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: -The correct answer is Arithmetic Logic Unit. Arithmetic Logic Unit (ALU): It performs all Arithmetic Operations and Decision-Making operations.
Detailed explanation-3: -Therefore ALU stands for Arithmetic Logic Unit (Option 4).
Detailed explanation-4: -An ALU consists of three types of functional parts: stor-age registers, operations logic, and sequencing logic, as shown in Fig. 1. The inputs and outputs of the ALU are connected to other functional units of the CPU, such as the cache memory and the program execution control unit.
Detailed explanation-5: -ALU is also known as an Integer Unit (IU). The arithmetic logic unit is that part of the CPU that handles all the calculations the CPU may need. Most of these operations are logical in nature.
