What is a top down design?

Top-down design is a problem-solving approach that starts with a high-level overview of a system and breaks it down into smaller, more manageable components. This method helps to organize and structure complex problems by first defining the main goal and then identifying sub-goals or functions that contribute to achieving that goal. The key advantage of top-down design is that it allows for systematic analysis and development, making it easier to manage complexity and ensure all parts of the system work together effectively.
