Madeeasy Test Series: Operating System - Process Schedule
For the given question instead of the given order if we take one unit of P2 as its arrival time is 1 and then schedule P1 next we get the same answer,even in the hint they have given as the process which comes first ... and the solution given ends up giving the same answer,does this happen for all cases or just happening for this question?

#OS Cpu scheduling doubt about SRTF turning into FCFS.
Let's say we have four processes as (P1, P2, P3, P4) and have Arrival time as (0,1,2,3) respectively, but all of them has same CPU Burst time as (10ms) then does SRTF will simply be behaving like FCFS?

#Galvin #CpuScheduling SJF VS SRTF Average waiting time doubt.
Let's say we have two CPU scheduling algorithm as SJF and SRTF and we have a arbitrary pool/set of processes with different ARRIVAL TIME and CPU BURST, then what CPU scheduling algorithm will result in minimum average ... values or when arrival times are different than SRTF will ALWAYS have the less average waiting time over SJF?

UGC NET CSE | December 2008 | Part 2 | Question: 8
Four jobs J1, J2, J3 and J4 are waiting to be run. Their expected run times are 9, 6, 3 and 5 respectively. In order to minimize average response time, the jobs should be run in the order: (A) J1 J2 J3 J4 (B) J4 J3 J2 J1 (C) J3 J4 J1 J2 (D) J3 J4 J2 J1

SJF Next burst prediction
Please help me in understanding the followign formulae? Prediction of the Length of the Next CPU Burst Pn+1 = a tn +(1-a)Pn This formula defines an exponential average Pn stores the past history tn contents are most recent information the parameter a ... a = 1 then Pn +1 = tn Prediction is last cpu burst I dont want to learn this.Please provide some logical explanation
