Now, if we want to look at the whole story of these state transition diagrams, then what we need to know is that there is always, in any sort of state transition diagram, only one single initial state. When the application under test i… A process is running if the process is assigned to a CPU.

You will see this is not complex, this is only complicated. And you probably start thinking about now the right way that this may actually make things complicated. Initial and Final States. > STD is used to develop an essential model of the system A model of how the system would behave if ew had perfect technology.
