The Arithmetic and Logic Unit (ALU) is a fundamental part of a computer’s central processing unit (CPU). It is responsible for performing all arithmetic operations, such as addition and subtraction, and logical operations, like comparisons and decision-making tasks. The ALU plays a critical role in ensuring that a computer can carry out complex calculations and data processing tasks efficiently. A strong understanding of the ALU helps in grasping how computers perform both simple and advanced operations.
Below are 10 multiple-choice questions (MCQs) designed to test your understanding of the Arithmetic and Logic Unit.
