System consists of components and properties.
The full set of properties existing at the current moment is called a System State.
Description of a System behaviour in response to or correlation with its properties is provided by a System Model.
Depending on whether a System has properties changing over time it can be a Static System or Dynamic System.
The changes of System State may happen as a direct consequence of the time flow or as response to the external factors (represented by Model Inputs in System Model).
