Top-Down Design Quiz: Test Your Knowledge

📚 Quick Study Guide

• ➗ Decomposition: Breaking down a complex problem into smaller, more manageable subproblems.
• 🌳 Modularization: Organizing the code into independent modules, each responsible for a specific task.
• 🎯 Abstraction: Hiding the complex implementation details and exposing only the essential information.
• 🔄 Iteration: Repeating the design process, refining each module until the desired functionality is achieved.
• 🧪 Testing: Rigorously testing each module to ensure it meets the specified requirements.
• 📐 Refinement: Gradually adding more detail and functionality to each module.
• 💡 Top-Down vs. Bottom-Up: Top-down starts with the overall system and breaks it down, while bottom-up starts with individual components and builds them up.

Practice Quiz

4. What is the role of iteration in the top-down design process?
   1. To continuously refine and improve the design
   2. To skip the testing phase
   3. To write the code only once
