real-time scheduling question 3 options: a real-time task's cpu utilization can be calculated by dividing the length of the period by its service time for one period. a periodic task is a job that is repeated at regular intervals. schedulability refers to a property indicating whether a real-time system (a set of real-time tasks) can meet its deadline. soft real-time systems must guarantee that real-time tasks will be serviced according to their deadline requirements. real-time systems apply an admission-control algorithm to decide whether a task is admitted (guaranteeing that it will complete on time) or rejected (if it cannot guarantee that the task will be serviced by its deadline).
