Abstraction (computer science)

Abstractions may also refer to vehicles, features, or rules of computational systems or programming languages that carry or utilize features of or abstraction itself, such as:

• the process or feature of using data types to perform data abstraction to decouple usage of from working representations of data structures within programs;^[6]
• the concept of procedures, functions, or subroutines which represent a specific way of abstracting of control flow in programs;
• the rules commonly named "abstraction" that generalize expressions using free and bound variables in the various versions of the lambda calculus;^[7][8]
• the usage of S-expressions as an abstraction of data structures and programs in the Lisp programming language;^[9]
• the process of reorganizing common behavior from non-abstract classes into "abstract classes" using inheritance to abstract over sub-classes as seen in the object-oriented C++ and Java programming languages.
