I have a question at 23:50! How can P1 and P4 be scheduled before P5 when P5 have a higher priority? Is this some kind of "fix" where you give all the processes the highest priority, just to ensure that the non-interactive processes will be run?
at 19:45 you say that P4 will go for its REMAINING 7 TIME UNITS, but the quantum is only 4 units. wont it switch at time 34 with P1? i have a midterm tomorrow, its probably too late for you to answer this. goodbye
no problem. I think why she did it that way is because of that the level 2 RR time quantum is 7. I'm writing it for the people who may have the same problem in the future.
For SJF CPU scheduler practice. after the first P3 on your Gantt chart, we are comparing p1_CPU=7, p2_CPU=4, P4_CPU=5, P5_CPU=3, at this point p5 is the shortest job. I didn't get why we will skip P5 and taking P2 instead.
Here is the starting time of each topic:
FCFS 00:00
SJF 07:37
MLFQ 12:45

P5 has a higher priority but it was waiting for I/O response, so it can't be scheduled yet.
thanks a lot , you explain it so well that I'm really enjoyed the video ...ECU

have you found the answer because i have a midterm for tomorrow too
özge I'm sorry it's been way too long I can't remember :(

the quantum is 7 units,because it is queue 2 not 1

i am not able to understand, how you have take the P1, P2,P3..... it is not going in sequence
can i ask how to find out the arrival time change in each time line running in the MLFQ?
Nice explanation!
What is the book reference (bibliograpy), please? Sorry my english, because I am brasilian and my english is bad.
what is meant by arrival time into ready queue?
thank you so much!
awesome !!! thanks a lot
thanks
do you can make it in french?
hindular daha iyi anlatıyo yaw
bence de
