Abstraction layerIn computing, an abstraction layer or abstraction level is a way of hiding the working details of a subsystem. Examples of software models that use layers of abstraction include the OSI model for network protocols, OpenGL, and other graphics libraries, which allow the separation of concerns to facilitate interoperability and platform independence. Another example is Media Transfer Protocol. In computer science, an abstraction layer is a generalization of a conceptual model or algorithm, away from any specific implementation.
