MCQ IN COMPUTER SCIENCE & ENGINEERING

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. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).

Detailed explanation-2: -ALU in the CPU ALUs perform arithmetic operations such as addition, subtraction, and multiplication, and logical operations such as NOR, NOT, AND, and OR. The arithmetic operation of division is typically done by another component of the CPU called a Floating-Point Unit, or FPU.

Detailed explanation-3: -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. Modern CPUs contain very powerful and complex ALUs.

Detailed explanation-4: -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.
