#10:40 Why my friend!!!!!! Why you decided to take 3 MS for P3? Based on FCFS is nonpreeamptive, so it should run the entire process!! Even though if you still following RR -> you should take only 2 MS! That is weird
Oh I think I got it, because p4 arrives at that time, the CPU jumps to run that process! I see. You would have mentioned that clearly my friend! But All good! I appreciate the efforts to make this video! It helped a lot!
Good question Abhay. Agreed that P3 is having FCFS but P3 was in a lower priority queue. Since this is a multi-level queue, the queue no 1 has higher priority. So as soon as CPU sees that there is a process (P4) coming in queue 1, even though it is processing P3 in FCFS it stops that and takes P4 on because P4 comes from a higher priority queue compared to P3. In Multi-level queue scheduling, priority set on the queues is taken first compared to what scheduling algorithm is used in the individual queues. Hope this solves your doubts 😇✌
but bro as u mentioned that Q2 uses FCFS scheduling algo then how it will stop the processing and switch to high priority process could you explain it??
Sure. Here is the full playlist of Scheduling algorithms. your topic is covered in this playlist :-) Link - th-cam.com/video/AiVKIdGheEU/w-d-xo.html If you liked the videos please do share the videos with your friends too. Thank you 😇
Most welcome buddy, please do share the videos with your friends too & I hope you have subscribed. Thats the biggest help and support you can provide ✌
As far as I know normally there is no preemptive FCFS. Although there can be some custom implementations but will have to check up on this. If you have any links or details do share it here so that I can check up and probably make a video too 👍

Pro tip: watch series on flixzone. Been using it for watching loads of movies during the lockdown.
@Matthias Nickolas Definitely, I've been watching on flixzone for years myself :D
@Matthias Nickolas Definitely, I've been using Flixzone for since november myself :D
WOW my guy I come from as far as Zimbabwe, but your explanations have no distance issues. Your videos have been helping me a lot. Thanks a lotTanmay
you have no idea how much i needed this , thank you so much

Thank you sir, really GREAT explanation keep going✨✨
i am having a hard time with this lesson thank you so much this is a huge help
This was very much helpful. God bless you ! You probably have to post more.
At 11:12 why p3 does not complete 8 sec as it is FCFS (non preemptive)?

Got it! Thank you for resolving my doubt. Btw, you teach very well. Best of luck :)
Thank you so much Abhay😇 really happy to hear this from you. Do share the videos with your friends too. That'll be the best help 😇✌️
Awesome explanation sir.........
Thanks bro 🤟 glad you liked it 😊
why p3 done for 3 seconds ? there is roundrobin value for 2 seconds?
Because p3 is in queue 2 which doesn't follow round robin ,it follows fcfs
Very nice explanation....!!!! great work bro
Most welcome my friend 😊✌️ I would request you to please share the video with your friends too ✌️
Thank you for explaining the concept so clearly...this was a huge help while preparing for my midterms.
Thank you so much Anvita. Do share it with your friends too 🙏😇 that'll be huge help
In one go ..... understood😍😍😍
Correction: TAT=CT-AT
I'm being confused abt this too😅
Really cool explanation keep going✨✨
Thank you! Will do!
Great explanation, thanks dude!
Glad you liked it! Please support me by sharing the videos and our channel with your friends too. Thats the biggest help and support you can provide 😇
@@SimpleSnippets i already did :))
but bro as u mentioned that Q2 uses FCFS scheduling algo then how it will stop the processing and switch to high priority process
could you explain it??
MY SAME ARGUMENT 😂
Can you please post a video about multilevel feed back queue scheduling algorithm
Sure. Here is the full playlist of Scheduling algorithms. your topic is covered in this playlist :-)

My friend have another question, in our OS course they are using response time, is it the same as waiting time, I don't see any difference!
Multilevel queue scheduling algorithm is preemptive or non-preemptive ?
Very very good. Blessings!
Thank you so much 😁 please do share the videos with your friends too✌
thankuuuuuuuuuuuuuuuuuuuuuuuuu sooooooooooooo muuuuuuuuccccccccccccccchhhhhhhhhhhhhhhhhhh sir
Most welcome buddy, please do share the videos with your friends too & I hope you have subscribed. Thats the biggest help and support you can provide ✌
Why p3 is executed for 3secs firstly?
Why P3 process is executed for 3 seconds when it came to the queue for first time?why not Directly for 8 seconds?
At 10th second, process P4 has arrived in higher priority queue 1, so it has to be executed first.
Bro tq so much for this video
Thank you so much lavanya 😇
Happy to hear your feedback. I would request you to share the videos with your friends too 😇🙏
Y p3 takes 3ms can't we take 5ms instead of 3ms
You videos awesome plz explain fcfs preemptive also
As far as I know normally there is no preemptive FCFS. Although there can be some custom implementations but will have to check up on this. If you have any links or details do share it here so that I can check up and probably make a video too 👍
@@SimpleSnippets thank you
Most welcome 😊
who else here adjust their play back speed to 0.75.lol
LOL me myself 😅
TAT might be CT-AT ?
Yes!
7 to 10(5) why
