Abstraction in philosophy is the process (or, to some, the alleged process) in concept formation of recognizing some set of common features in individuals, and on that basis forming a concept of that feature. The notion of abstraction is important to understanding some philosophical controversies surrounding empiricism and the problem of ...
An example of this abstraction process is the generational development of programming language from the machine language to the assembly language and the high-level language. Each stage can be used as a stepping stone for the next stage. The language abstraction continues for example in scripting languages and domain-specific programming languages.
Abstraction in mathematics is the process of extracting the underlying structures, patterns or properties of a mathematical concept, removing any dependence on real world objects with which it might originally have been connected, and generalizing it so that it has wider applications or matching among other abstract descriptions of equivalent phenomena.
Abstraction Definition Usage Variable: A storage location paired with an associated symbolic name that contains some known or unknown quantity of information referred to as a value. Typically used in all programming paradigms. Function: An abstraction representing a set of instructions that can be applied to input data to produce output.
A kind of abstraction commonly considered in linguistics is the phoneme, which abstracts speech sounds in such a way as to neglect details that cannot serve to differentiate meaning. Other analogous kinds of abstractions (sometimes called "emic units") include morphemes, graphemes and lexemes.
In philosophy and the arts, a fundamental distinction is between things that are abstract and things that are concrete.While there is no general consensus as to how to precisely define the two, examples include that things like numbers, sets, and ideas are abstract objects, while plants, dogs, and planets are concrete objects.

Abstractionism is the theory that the mind obtains some or all of its concepts by abstracting them from concepts it already has, or from experience. [1] One may, for example, abstract 'green' from a set of experiences which involve green along with other properties.
In 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.
