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:

    A man’s most open actions have a secret side to them.
    Joseph Conrad (1857–1924)

    Loving feels lonely in a violent world,
    irrelevant to people burning like last year’s weed
    with bellies distended, with fish throats agape
    and flesh melting down to glue.
    We can no longer shut out the screaming
    That leaks through the ventilation system ...
    Marge Piercy (b. 1936)
