Open System
an entity with a boundary that is not closed. It receives input s and produces outputs. (Umpleby )
A system with input , an entity that changes its behavior in response to conditions outside its boundaries. Systems are rarely ever either open or closed but open to some and closed to other influences (see channel ). Because of their need to combat decay within, food intake makes biological organisms and societies open to matter/ENERGY from their environment. But this property says nothing about openness to information. adaptation, learning and all manifestations of intelligence require some openness to information. Unlike biological organisms, computers and social institutions exemplify openness to organization which indicates that structural changes are determined from the outside. Whether or not a system has outputs does not enter the distinction between open and closed systems. Systems without output are non-knowable by an external observer, e.g., black holes in the visible universe (see ether ). Systems without inputs are not controllable (see control, closed system ).

Open system
An open system may refer to:
- Open system (computing), one of a class of computers that provides some combination of interoperability, portability and open software standards, particularly Unix and Unix-like systems
- Open system (computer science), in the computer sciences a collection of interacting software, hardware, and human components with well-defined, publicly available interfaces maintained by a consensus process
- Open system (management science), in management science a system that is capable of self-maintenance on the basis of throughput of resources from the environment
- Open system (systems theory), a system where matter or energy can flow into and/or out of the system, in contrast to a closed system, where energy can enter or leave but matter may not

Open system (computing)
Open systems are computer systems that provide some combination of interoperability, portability, and open software standards. (It can also mean systems configured to allow unrestricted access by people and/or other computers; this article only discusses the first meaning.)
The term originated in the late 1970s and early 1980s, mainly to describe systems based on Unix, especially in contrast to the more entrenched mainframes and minicomputers in use at that time. Unlike older legacy systems, the newer generation of Unix systems featured standardized programming interfaces and peripheral interconnects; third party development of hardware and software was encouraged, a significant departure from the norm of the time, which saw companies such as Amdahl and Hitachi going to court for the right to sell systems and peripherals that were compatible with IBM's mainframes.
