An abstraction layer (or abstraction level, or a layer of abstraction) is a way of hiding the implementation details of a particular set of functionality. Software models that use layers of abstraction include the OSI 7-layer model for computer network protocols, the OpenGL graphics drawing library, and the byte stream input/output (I/O) model originated by Unix and adopted by MSDOS, Linux, and most other modern operating systems.
