FCFS ??

---

answer is FCFS

---

answer given is 1,3,4

---

Yes answer may vary depending on what factor we consider to break the tie.

If we think in non preemptive way

then answer is either FCFS or Highest priority first

and if we think in preemptive manner

then answer can be Shortest remaining first but here also to decide the order in which processes will be given cpu for the very first time will be decided on the basis of arrival time

---

but Round Robin also degenerates to FCFS if Time Quantum is greater than all burst time

---

Answer should be 1,2,4.

---

If the CPU burst time of all processes are equel.Then how can we implement SRTF??

Answer 1

taken form, Galvin. we also use the highest priority first to break the tie by assigning priority to process.
