System Analysis And Design Quizzes & Trivia

System analysis refers to the procedure of gathering and clarifying facts, recognizing the difficulty or issues, and disintegration of a system into its parts. It improves the system, and the parts work efficiently. Whereas, system design is the process of replacing a system by describing the part or modules. This quiz has been designed to test your knowledge about the process. Let's try to out the quiz. All the best!
