Open System: A model of computing systems that provides some form of openness, such as open standards, interfaces, or source code. This openness promotes interoperability, portability, and user choice and allows users and developers to have significant influence over how the system operates. Open systems are often contrasted with closed systems, which are controlled by a single entity and where the inner workings of the system are not made available to users or developers.
