Question

es. 7. Design a scheduling program to implements a Queue with two levels:

Level 1 : Fixed priority preemptive Scheduling

Level 2 : Round Robin Scheduling

For a Fixed priority preemptive Scheduling (Queue 1), the Priority 0 is highest priority. If one

process P1 is scheduled and running , another process P2 with higher priority comes. The New

process (high priority) process P2 preempts currently running process P1 and process P1 will go

to second level queue. Time for which process will strictly execute must be considered in the

multiples of 2..

All the processes in second level queue will complete their execution according to round robin

scheduling.

Consider: 1. Queue 2 will be processed after Queue 1 becomes empty.

2. Priority of Queue 2 has lower priority than in Queue 1.​
