Editing Abstraction (computer science) (section)

===Layered architecture===
{{Further|Abstraction layer}}
The ability to provide a [[design]] of different levels of abstraction can

* simplify the design considerably
* enable different role players to effectively work at various levels of abstraction
* support the portability of [[software artifact]]s (model-based ideally)

[[Systems design]] and [[Business process modeling|business process design]] can both use this. Some [[Software modeling|design processes]] specifically generate designs that contain various levels of abstraction.

Layered architecture partitions the concerns of the application into stacked groups (layers).
It is a technique used in designing computer software, hardware, and communications in which system or network components are isolated in layers so that changes can be made in one layer without affecting the others.
