"Real Time", a term whose meaning is more in the mind of the beholder than cast in linguistic concrete. In fact, the community recognizes this confusion by defining two sorts of real-time - "hard" and "soft". A hard real time task or system is one where an activity simply must be completed - always - by a specified deadline. The deadline may be a particular time or time interval, or may be the arrival of some event. Hard real time tasks fail, by definition, if they miss such a deadline. Notice this definition makes no assumptions about the frequency or period of the tasks. A microsecond or a week - if missing the deadline induces failure, then the task has hard real time requirements.
