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: -The arithmetic logic unit (ALU) performs mathematical calculations; it is the part that computes.

Detailed explanation-3: -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-4: -The arithmetic logic unit (ALU) performs the arithmetic and logical functions that are the work of the computer. The A and B registers hold the input data, and the accumulator receives the result of the operation. The instruction register contains the instruction that the ALU is to perform.

Detailed explanation-5: -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.
