encapulate

Encapulate is a term that can refer to several related concepts, primarily within the realm of technology and programming. In object-oriented programming, encapsulation is a fundamental principle that bundles data (attributes) and the methods (functions) that operate on that data within a single unit, often called a class. This means that the internal state of an object is hidden from the outside world, and access to it is controlled through its methods. This promotes data integrity by preventing direct manipulation of data from outside the object, and it also makes the code more modular and easier to maintain. Changes to the internal implementation of a class do not necessarily affect other parts of the program that use the class, as long as the public interface remains the same.

Beyond object-oriented programming, the term "encapsulate" can also be used more generally to describe the act of enclosing or containing something within another thing. For instance, in networking, data packets are encapsulated within larger data structures as they travel through different layers of the network protocol stack. Each layer adds its own header information, effectively "encapsulating" the data from the layer above. This process of encapsulation and de-encapsulation is crucial for the functioning of modern communication systems. The core idea across these different contexts is the creation of a protective layer or boundary that controls access and manages the contained information.
