your lectures is helping me since the beginning of my university life. I have to confess that i have learnt more from your lectures than my class lectures, reading books and other sources.
Thanks a lot sir,With your lectures on this topics ,I understood all the concepts and yesterday I wrote my mid exam of operating systems very well ,just because of you.You are teaching very well compared to my faculty ,I just got impressed by listening your lectures.Once Again thanks a lot Sir..
For those who are having troubles with priority and priority number relationship, it depends entirely on the OS and doesn't follow any general rule, even if u design an OS someday you would have freedom to choose b/w either of paradigms.
Came to watch educational video but amazon prime disturbed me and now i came after 4 hours and this is bcz of youtube senseless ads it has no sense it should provide educational ads
The lower the priority number the HIGHER the priority, according to my textbook. Process 1 with priority "2", has a higher priority than Process 2 with priority number "4". Your algorithm explanation is correct though.
as the waiting time is the time when a process is in ready queue so for p2 the time in which it is in ready queue is (21-2)+(1-0)=20 then why it is 19???
sir preemptive priority scheduling method is very good for understanding , so much thankyou for this. please also give tutorial for sjf preemptive scheduling algorithm .
The only difference between preemption and nonpremption is that. In preemption after processing the the process with 0th arrival time then we go to next with higher priority before the previous one is finished and continue it till all the processes come into the queue. Then we finish the whole process according to the queue. In non_preemption after executing the the process with arrival time 0 we go with higher priority and finish each one of the processes. Means don't stop the process until it's executed fully.
if a priority can be represented using 10 bits and the priority of a waiting process gradually increases by 1 every 1 minute, then what would be the maximum waiting time of the lowest priority process? what will happen in this scenario ??
what if arrival time for p3 would be 4, p4 = 5 and so on..then what would the cpu be after cpmpletion of p1 and p2..would it remain idle or performs the previous left out process until higher priority process arrives?
hello Ravindrababu, thank you for the explanation. I have a question, whatever is the priority for the first task, we need to execute the first task and then, depending on the arrival time and the priority the other tasks gets executed. Is this right?
hi what happens if we encounter the process with same priority waiting in ready queue for example if process with priority 1 is running and again process with same priority is waiting ready queue , please explain this situation
sir do we have a chance of having arrival time which is not having a equal intervals like Eg:- 0,1,5,9,10,12,16 if this is the case how much execution time we have to consider while we are writing gantt chart. please help me out
sorry sir if i am wrong what I studied is lower the priority number higher the priority, see na when we give rank to anyone who is topper or higher we give him 1 and who is lower we give him higher rank eg 65,66 etc
your videos are great but the sound quality is a bit average sir. I would and I think some would really appreciate it more if the sound quality is more better sir thank you.
Soham Basu it depends. as he told already, some times they mention lower the number higher the priority and some times they mention higher the number higher the priority

I got the same question in my exam with same data.... Thanxx alot😂 🙏
Lucky you
Great video !! All your lectures are concise and informative .. Thank you .
In case of priority, lower the number higher the priority.....
for example.
1 has higher priority than 2,3,4....n .
+Chandan Singh it depend on questions , in this case he assumed that the higher number is the higher priority , its okey
Best ever teaching...great work😊
you just forgeted to mention in your case you assumed that the higher number is the higher priority , well done its very clear
In case of priority lower the priority number gets the higher priority like priority 1 is higher than 2,3,4

what if priority is not mentioned?

Gud explanation... tnq for all the videos
The lower the priority number the HIGHER the priority, according to my textbook. Process 1 with priority "2", has a higher priority than Process 2 with priority number "4". Your algorithm explanation is correct though.
Chris Botha This is true for my CS course as well, lower priority number means higher priority
as the waiting time is the time when a process is in ready queue so for p2 the time in which it is in ready queue is (21-2)+(1-0)=20 then why it is 19???
sir preemptive priority scheduling method is very good for understanding , so much thankyou for this.
please also give tutorial for sjf preemptive scheduling algorithm .
SJF is non pre-emptive. I think you meant SRTF.
I think the process which arrive first is to be executed irrespective of priorities... ??
sir your explanation is very good i have challenge that when we have a equal priority do we follow arrival time
Will there will be a difference in answer if the question is NOT given in ascending order of Arrival time. Can we make it ascending ?
The only difference between preemption and nonpremption is that. In preemption after processing the the process with 0th arrival time then we go to next with higher priority before the previous one is finished and continue it till all the processes come into the queue.
Then we finish the whole process according to the queue.
In non_preemption after executing the the process with arrival time 0 we go with higher priority and finish each one of the processes. Means don't stop the process until it's executed fully.
your explanation is awesome
If priority is not given in the question what ll be the first
Lower number or higher number priority
if a priority can be represented using 10 bits and the priority of a waiting process gradually increases by 1 every 1 minute, then what would be the maximum waiting time of the lowest priority process? what will happen in this scenario ??
In Gantt chart, wasn't the completion time of P4 supposed to be 3+5 that is 8 (as 5 is the BT initially) ?
What if 2 process’s have the same priority and have already arrived, should we then take account of their arrival time?
what if arrival time for p3 would be 4, p4 = 5 and so on..then what would the cpu be after cpmpletion of p1 and p2..would it remain idle or performs the previous left out process until higher priority process arrives?
hello Ravindrababu, thank you for the explanation. I have a question, whatever is the priority for the first task, we need to execute the first task and then, depending on the arrival time and the priority the other tasks gets executed. Is this right?
oh, he said "this rough work"! When I first listened I thought he said, "this...Fuck!".
great sir .....
What will be the execution order if process P6 have burst time 1?
hi what happens if we encounter the process with same priority waiting in ready queue
for example if process with priority 1 is running and again process with same priority is waiting ready queue , please explain this situation
sir do we have a chance of having arrival time which is not having a equal intervals like Eg:- 0,1,5,9,10,12,16 if this is the case how much execution time we have to consider while we are writing gantt chart. please help me out
sir do we have a chance of having arrival time which is not having a equal intervals like Eg:- 0,1,5,9,10,12,16
sir,you teach so good
how to compute if the arrival time for all the processes is o
Go with lesser process id
Sir osm teaching...!
sorry sir if i am wrong what I studied is lower the priority number higher the priority,
see na when we give rank to anyone who is topper or higher we give him 1 and who is lower we give him higher rank eg 65,66 etc
What if two processes have the same priority , then which one should be executed first ?
i think you should check the arrival time then...
your videos are great but the sound quality is a bit average sir. I would and I think some would really appreciate it more if the sound quality is more better sir thank you.
well explained sir....
Priority Scheduling is a non-preemtive scheduling algorithm.
Where is the preemptive sjf ?
How to solve preemptive priority example if priority is not given.
it was really good explanation
ugggh i cant comprehend him.
Kuch dikh hi nhi rha english hindi conversation cover all blackboard
thanks bro you have clearify my doubt
What if the priority of 2 processes is same what should we do then??? Which one to choose
Sagar Rijhwani arival time. which process arrived frist it would be executed first
What if arrival time for all is zero sir plz answer I have exams on Monday n I m bit confuse !
You look like Sunil Shetty! :D
Btw Awesome video! :)
Ravindrababu Ravula sir ,i have one question is there any difference between waiting time and average waiting time;.plz reply
Can "Arrival Time" be fraction?
mistake in waiting time calculation
Keep rocking brother
please give ans quikly becuase today wrote pepae i did the same method but other did another but ans got different
Sir on what basis you assigned priority to each process???
Do u have all the lectures available for all subjects of computer engineering gate syllabus
yes
sir super .....
Isn't lower the number higher the priority?? Please explain; Thank you
Soham Basu My CS course says lower priority number means higher priority level
Soham Basu it depends. as he told already, some times they mention lower the number higher the priority and some times they mention higher the number higher the priority
waiting time ka formula wt=TAT- burst time right hai kya non preemtive case mai
yes
It was very tough.I couldn't understand the explanation
Very helpful
Thanks sir
Thanks god
sir,preemptive is good .
Tnq U sir..
is this a tutorial?????. how will we understand.....
but good to see trying....
isnt this wrong lower the value higher the priority it has to be
Thank you so much sir🙏
I watched all of your videos.But after this I am not sure
Thank you so much sir!
i luv u sir!!!
awesome
Didn't get you ...
Ravindrababu Ravula
Legendary name
Smallest integers have the highest priority..This is incorrect
He said it is mentioned in the Question.
it's true?????? why others youtuber no same as you
yoyo
sir u have only test practice serious
i'dont understant
simo mohamed Ba keep try
nice
your acent is strong hard to understand
Hey man, the highest priority there is 2 not 12. Please review your video again
tysm sir
My savior ! Thank you sir _/\_
wrong job
Slow down the explanation. You are moving too fast.
you moving too fast man........
Oh too much accent
What if 2 process’s have the same priority and have already arrived, should we then take account of their arrival time?
