'''System''' (from Latin systēma, in turn from Greek σύστημα systēma) is a set of interacting or [[Interdependence|interdependent]] entities, real or abstract, forming an integrated whole.

The [[concept]] of an 'integrated whole' can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the set and elements not a part of the relational regime.

The scientific [[research]] field which is engaged in the study of the general properties of systems include [[systems theory]], systems science, systemics and systems engineering. They investigate the [[abstract]] properties of the [[matter]] and organization, searching [[concepts]] and principles which are independent of the specific domain, substance, type, or temporal scales of [[existence]].

Most systems share the same common characteristics. These common characteristics include the following

* Systems are abstractions of [[reality]].
* Systems have [[structure]] which is defined by its parts and their composition.
* Systems have [[behavior]], which involves inputs, processing and outputs of material, [[information]] or [[energy]].
* Systems have interconnectivity, the various parts of a system have functional as well as structural relationships between each other.

The term system may also refer to a set of rules that governs [[behavior]] or [[structure]].
