A system is a set of interacting or interdependent components forming an integrated whole or a set of elements (often called 'components' ) and relationships which are different from relationships of the set or its elements to other elements or sets.
Fields that study the general properties of systems include systems theory, cybernetics, dynamical systems, thermodynamics, and complex systems. They investigate the abstract properties of systems' matter and organization, looking for concepts and principles that are independent of domain, substance, type, or temporal scale.
Some systems share common characteristics, including:
- A system has structure, it contains parts (or components) that are directly or indirectly related to each other;
- A system has behavior, it contains processes that transform inputs into outputs (material, energy or data);
- A system has interconnectivity: the parts and processes are connected by structural and/or behavioral relationships.
- A system's structure and behavior may be decomposed via subsystems and sub-processes to elementary parts and process steps.
The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term institution is used to describe the set of rules that govern structure and/or behavior.

Famous quotes containing the word system:
“Authority is the spiritual dimension of power because it depends upon faith in a system of meaning that decrees the necessity of the hierarchical order and so provides for the unity of imperative control.”
—Shoshana Zuboff (b. 1951)
“We now come to the grand law of the system in which we are placed, as it has been developed by the experience of our race, and that, in one word, is SACRIFICE!”
—Catherine E. Beecher (1800–1878)
“I have no concern with any economic criticisms of the communist system; I cannot enquire into whether the abolition of private property is expedient or advantageous. But I am able to recognize that the psychological premises on which the system is based are an untenable illusion. In abolishing private property we deprive the human love of aggression of one of its instruments ... but we have in no way altered the differences in power and influence which are misused by aggressiveness.”
—Sigmund Freud (1856–1939)
