What is the full form of ALU?
 A Arithmetic Long Unit B Arithmetic and Logical Unit C None of these D None of the above
Explanation:

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 full form of ALU is Arithmetic Logic Unit. Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit).

Detailed explanation-3: -The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the programâ€™s instructions and data.

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.

Detailed explanation-5: -In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.
