Information Hiding is a principle in software design that focuses on restricting access to certain details of a system. By concealing the inner workings of a component, developers can protect the integrity of the system and reduce complexity. This allows users to interact with the component without needing to understand its intricate details. This concept is often applied in object-oriented programming, where classes encapsulate data and expose only necessary methods. By doing so, programmers can create more modular and maintainable code, making it easier to update or change parts of the system without affecting other components.
