There are natural and man-made (designed) systems. Man-made systems normally have a certain purpose, objectives. They are “designed to work as a coherent entity”. Natural systems may not have an apparent objective.

A system is a fundamental concept of systems theory, a way of thinking about the world, a model. We determine a system by choosing the relevant interactions we want to consider, plus choosing the system boundary —– or, equivalently, providing a membership criteria to determine which entities are part of the system, and which entities are outside of the system and are therefore part of the environment of the system.

An open system usually interacts with some entities in their environment. A closed system is isolated from its environment.

A subsystem is a set of elements, which is a system itself, and a part of a larger system.

Overview

The scientific research field which is engaged in the transdisciplinary study of universal system-based properties of the world is general system theory, systems science and recently systemics. They investigate the abstract properties of the matter and mind, their organization, searching concepts and principles which are independent of the specific domain, independent of their substance, type, or spatial or temporal scales of existence.

The term system has multiple meanings :

A collection of organized things; as, a solar system.; A way of organising or planning.; A whole composed of relationships among the members.;

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

Systems have a structure that is defined by its parts and processes.; Systems are generalizations of reality.; Systems tend to function in the same way. This involves the inputs and outputs of material (energy and/or matter) that is then processed causing it to change in some way.; The various parts of a system have functional as well as structural relationships between each other.;

The characteristics of systems have been studied in general systems theory.

History

The term System has a long history which can be traced back to the Greek language.

In the 19th century the first to develop the concept of a "system" in the natural sciences was the French physicist Sadi Carnot who studied thermodynamics. In 1824 he studied what he called the working substance (system), i.e. typically a body of water vapor, in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a heat reservoir (a boiler), a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.
