It is useful in real-time systems to distinguish between two forms of computation that occur at run-time: tasks and event handlers. A real-time task (or thread) is a long-lived entity with state and periods of activity and inactivity. While active, it competes with other tasks for the available resources – the rules of this competition are captured in a scheduling or dispatching policy (for example, fixed priority or EDF).
