Computer science commonly presents levels (or, less commonly, layers) of abstraction, wherein each level represents a different model of the same information and processes, but with varying amounts of detail. Each level uses a system of expression involving a unique set of objects and compositions that apply only to a particular domain.
Design patterns in computer science represent abstract solutions to common software design problems. While they are not abstractions in the same sense as data structures or mathematical concepts, design patterns provide a high-level language for software developers to communicate and implement solutions in a consistent and recognizable way.
Abstraction requires selective use of this structural split of abilities in the psyche. The opposite of abstraction is concretism. Abstraction is one of Jung's 57 definitions in Chapter XI of Psychological Types. There is an abstract thinking, just as there is abstract feeling, sensation and intuition. Abstract thinking singles out the rational ...
In computer science, an abstract state machine (ASM) is a state machine operating on states that are arbitrary data structures (structure in the sense of mathematical logic, that is a nonempty set together with a number of functions and relations over the set).
The theorem does not describe an actual theorem that can be proven; rather, it is a general principle for managing complexity through abstraction. The theorem is often expanded by the humorous clause "…except for the problem of too many levels of indirection", referring to the fact that too many abstractions may create intrinsic complexity ...
In computer science, an abstraction layer is a generalization of a conceptual model or algorithm, away from any specific implementation. These generalizations arise from broad similarities that are best encapsulated by models that express similarities present in various specific implementations.
A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture, memory or underlying physical hardware; commands or functions in the language are structurally similar to a processor's instructions. These languages provide the programmer with full control over ...
In computer science, an abstract machine is a theoretical model that allows for a detailed and precise analysis of how a computer system functions. [1] It is similar to a mathematical function in that it receives inputs and produces outputs based on predefined rules.
