FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -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.

Detailed explanation-3: -ALUs enable mathematical procedures to be performed in an optimized manner, and this can significantly reduce the number of steps required to perform a particular calculation. Today, most CPUs (Central Processing Unit) contain ALUs which can perform operations on 32 or 64-bit binary numbers.

Detailed explanation-4: -The arithmetic/logic unit (ALU) contains the electronic circuitry that executes all arithmetic and logical operations. The arithmetic/logic unit can perform four kinds of arithmetic operations, or mathematical calculations: addition, subtraction, multiplication, and division.

Detailed explanation-5: -The arithmetic logic unit is that part of the CPU that handles all the calculations the CPU may need, e.g. Addition, Subtraction, Comparisons. It performs Logical Operations, Bit Shifting Operations, and Arithmetic Operation. Accumulator (ACC): Stores the results of calculations made by ALU.
