With Round-Robin CPU scheduling in a time shared system.

Consider the following statements:

S1 : If all jobs arrive at the same p oint in time, a SJF and an SRTF scheduler will behave the same.

S2 : If all jobs arrive at the same point in time and have identical run lengths, a FIFO and a SJF scheduler will behave the same.

S3 : If all jobs have identical run lengths, a RR scheduler provides better average turnaround time than FIFO

S4 : With a MLFQ scheduler, high priority jobs have longer time-slices than low priority jobs.
