title: difference between state chart,state machine diagrams and state transition diagrams
body: <p>what are the differences between <strong>state chart diagrams</strong>, <strong>state machine diagrams</strong> and <strong>state transition diagrams</strong>?
  while at several places i got to learn that state chart diagrams and state machine diagrams mean the same thing but at some places it is shown as different.i could only make out that state chart diagrams represent states the system is in at a moment of time while state machine diagrams show the objects and transitions between them throughout their lifetime.</p>
