Open System (systems Theory)

Open System (systems Theory)

An open system is a system which continuously interacts with its environment. The interaction can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept (see below). An open system should be contrasted with the concept of an isolated system which exchanges neither energy, matter,nor information with its environment.

The concept of an "open system" was formalized within a framework that enabled one to interrelate the theory of the organism, thermodynamics, and evolutionary theory. This concept was expanded upon with the advent of information theory and subsequently systems theory. Today the concept has its applications in the natural and social sciences.

Famous quotes containing the words open and/or system:

    Wild Bill was indulging in his favorite pastime of a friendly game of cards in the old No. 10 saloon. For the second time in his career, he was sitting with his back to an open door. Jack McCall walked in, shot him through the back of the head, and rushed from the place, only to be captured shortly afterward. Wild Bill’s dead hand held aces and eights, and from that time on this has been known in the West as “the dead man’s hand.”
    State of South Dakota, U.S. public relief program (1935-1943)

    When the finishing stroke was put to his work, it suddenly expanded before the eyes of the astonished artist into the fairest of all the creations of Brahma. He had made a new system in making a staff, a world with full and fair proportions; in which, though the old cities and dynasties had passed away, fairer and more glorious ones had taken their places.
    Henry David Thoreau (1817–1862)
