## What is Information Hiding Principle? The Information Hiding Principle is a concept in software engineering that suggests that the design or implementation details of a component should be hidden from other components. This means that other parts of the software should not rely on a component's internal implementation and should only interact with it through its public interface. This principle promotes modularity and separation of concerns, which makes the system more flexible, easier to maintain and less prone to errors. It also enhances security as sensitive data is kept private. Information hiding is commonly achieved through encapsulation in object-oriented programming, where an object's data (attributes) and code (methods) are bundled together, and access to the data is restricted to the object's methods.
