Abstraction is a term widely used in computer science to represent a number of related concepts. Most commonly this is:

The mechanism and practice of reducing and factoring out details so that one can focus on a few concepts at a time.

Also:

Something (be it a class, component, idea) that is not related to a concrete instance.
A simplification of something more complicated to hide unnecessary information.
The process of considering something independently of its associations, attributes, or concrete accompaniments.
