16.Discuss the difference between a time-triggered real-time system and an event-triggered real-time system.

17.Analyze how interrupt and trigger tasks deal with task activation in different ways.

18.Assume that there is a large difference between the experimentally observed WCET and the analytically calculated WCET. What can you learn from this difference? How can you reduce the difference? What are the problems with the experimental measurement of the WCET?

19.Explain the difference between a continuous real-time entity and a discrete real-time entity.

20.What is the difference between a state observation and an event observation? Why are event observations more efficient than state observations in a case where the real-time entity does not change frequently?
