Which of the following statements are true?

I.    Shortest remaining time first scheduling may cause starvation
II.   Preemptive scheduling may cause starvation
III.  Round robin is better than FCFS in terms of response time
(A) I only             (B) I and III only             (C) II and III only            (D) I, II and III

Answer

ANSWER: (D)

EXPLANATION:

In SJF, process will cause starvation if a large CPU burst required process is there.

In Preemptive scheduling, always 1 process preempt due to low priority then due to this starvation take place.

In RR, every process 1st response gets after certain time quantum so due to this it give more better than FCFS in term of response time.
