Question

plz anyone haveing this question answare.
To design a scheduling program to implement 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.
Here Queue 2 will be processed after Queue 1 becomes empty.
2. Priority of Queue 2 has lower priority than in Queue 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.

Here Queue 2 will be processed after Queue 1 becomes empty.

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