Multilevel Queue Scheduling
Largest Job First
The interval from the time of submission of a process to the time of completion.
The sum of periods spent waiting in the ready queue.
The sum of periods spent executing on CPU.
The time when the process first responds.
The currently executing process will be preempted and the new process will be assigned to the CPU.
The CPU will keep on executing the current process and the new process has to wait in the ready queue.
The new process will be shifted to I/O queue.
The system will crash.
The priority of a process decreases after sometime. (moves away from 1)
The priority of a process increases after sometime. (moves closer to 1)
The priority remains constant.
The process becomes old and doesn't execute.
The process coming first is executed first without preemption.
The processes are executed according to their priority.
The process having the smallest burst time is executed first.
The process is executed for a time quantum and when the time quantum expires, the process enters into waiting state.
