Answer:
Rate-monotonic
Step-by-step explanation:
Rate-monotonic scheduling is used in real-time operating systems (RTOS). It is a priority assignment algorithm. The priorities are assigned according to the duration of the task. Task that require shorter time are given higher priority while the task which requires more time is given lower priority.
Here the operating systems are of preemptive type. This means that the operating system might interrupt a task which is being processed.
