System (from Latin Latin is an Italic language originally spoken in Latium and Ancient Rome. With the Roman conquest, Latin was spread to countries around the Mediterranean, including a large part of Europe. Romance languages, such as Catalan, French, Italian, Portuguese, Romanian, and Spanish, are descended from Latin, while many others, especially European systēma, in turn from Greek Greek , an independent branch of the Indo-European family of languages, is the language of the Greeks. Native to the southern Balkans, it has the longest documented history of any Indo-European language, spanning 34 centuries of written records. In its ancient form, it is the language of classical ancient Greek literature and the New Testament of σύστημα systēma) is a set of interacting or interdependent entities An entity is something that has a distinct, separate existence, though it need not be a material existence. In particular, abstractions and legal fictions are usually regarded as entities. In general, there is also no presumption that an entity is animate. Entities are used in system developmental models that display communications and internal 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 In systems science, systems theory is an interdisciplinary theory about the nature of complex systems in nature, society, and science, and is a framework by which one can investigate and/or describe any group of objects that work together to produce some result. This could be a single organism, any organization or society, or any electro-, cybernetics Cybernetics is the interdisciplinary study of the structure of regulatory systems. Cybernetics is closely related to control theory and systems theory. Both in its origins and in its evolution in the second-half of the 20th century, cybernetics is equally applicable to physical and social systems, dynamical systems The dynamical system concept is a mathematical formalization for any fixed "rule" which describes the time dependence of a point's position in its ambient space. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each spring in a lake and complex systems Complex systems is a scientific field which studies the common properties of systems that are considered fundamentally complex. Such systems are used to model processes in biology, economics, physics and many other fields. It is also called complex systems theory, complexity science, study of complex systems, sciences of complexity, non-. 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 common characteristics, including:
- Systems have structure Structure is a fundamental and sometimes intangible notion covering the recognition, observation, nature, and stability of patterns and relationships of entities. From a child's verbal description of a snowflake, to the detailed scientific analysis of the properties of magnetic fields, the concept of structure is an essential foundation of nearly, defined by parts and their composition;
- Systems have behavior Behavior or behaviour refers to the actions or reactions of an object or organism, usually in relation to the environment. Behavior can be conscious or subconscious, overt or covert, and voluntary or involuntary, which involves inputs, processing and outputs of material, energy or information;
- Systems have interconnectivity Interconnectivity is a concept that is used in numerous fields such as cybernetics, biology, ecology, network theory, and non-linear dynamics. The concept can be summarized as that all parts of a system interact with and rely on one another simply by the fact that they occupy the same system, and that a system is difficult or sometimes impossible: 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.
