Encapsulation is a technique that encourages decoupling. All object-oriented programming (OOP) systems support encapsulation, [2] [3] but encapsulation is not unique to OOP. Implementations of abstract data types, modules, and libraries also offer encapsulation.
Encapsulation is the computer-networking process of concatenating layer-specific headers or trailers with a service data unit (i.e. a payload) for transmitting information over computer networks.
Encapsulation (networking), the process of adding control information as it passes through the layered model Encapsulation (computer programming) , the combination of program code and data, and/or restriction (hide) of access to data except through dedicated code
Encapsulation is a means of information hiding. [2] Layered designs in information systems are another embodiment of separation of concerns (e.g., presentation layer, business logic layer, data access layer, persistence layer). [3] Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or ...
Data encapsulation, also known as data hiding, is the mechanism whereby the implementation details of a class are kept hidden from the user. The user can only perform a restricted set of operations on the hidden members of the class by executing special functions commonly called methods to prevent attributes of objects from being easily viewed and accessed.
Encapsulation is a technique that encourages decoupling. In object oriented programming, objects provide a layer which can be used to separate internal from external code and implement abstraction and encapsulation.
Encapsulation also protects the integrity of the component, by preventing users from setting the internal data of the component into an invalid or inconsistent state. Another benefit of encapsulation is that it reduces system complexity and thus increases robustness, by limiting the interdependencies between software components.
In order to do this, the protocol (lower) layer will add to the SDU certain data it needs to perform its function; which is called encapsulation. For example, it might add a port number to identify the application, a network address to help with routing, a code to identify the type of data in the packet and error-checking information.
