Life mai pehli baar OS padhne mai maza aa raha hai Lakshay Bhaiya OP :)

[@AnantMehra7]

Really OP Lectures Sir. But we all need to appreciate the combinations of Pen's Ink Colour that this channel uses for writing. Totally out of the league for any other channel to understand. This level of " Desh Prem ", Amazing, simply loved it.

Mst padhate hain yrr bhaiya , mtlb jaise ek dost smjhata hai aur sb smjh aata hai bilkul waise.

[@0708Sunshine]

nye lecture ke liye dhanyawaad, will definitely be waiting for the next one! your efforts are highly appreciated :)

[@nikitapanwar5529]

Best content ..mind blowing ..Thankyou bhaiya for the OS series..only one request please upload videos on daily basis..

[@mohitbansal321]

unko bhi thoda kam hota ha sabar rakha kro

[@kaizen6163]

Bhaiya, There is a mistype. Completion time should be time at which the process is terminated instead of time taken to the process to be terminated.

[@beginner9599]

Yup. But he explain it that way.

[@AradhyaSingh-un8di]

correct there is typo in that.. which can create confusion to distinguish between tat and ct..

Really Really Good Explanation of Convoy Effect.

[@prashantlalwani527]

23:13 why time sharing effect is not considered here?? in convoy effect

[@abhipsaacharya8031]

Because fcfs is a non-preemptive scheduling algorithm.

[@deepikasharma9812]

get to know the concepts that i skipped .....thank you guru ji !!

Non- preemptive me low cpu utilisation kese hoga wo kha idle betha hai????

[@shivkumar-og4ow]

Thank you bhaiya.. For your Hard work and good content provide

[@HemangSinghal-op5ep]

In the first example, shouldn't the turn around time for the 3rd process be 22 instead of 23

Doubt : in non-preemptive cpu utilization mus be higher than preemptive. because context switching ke time pe cpu ideal hota h, since preemptive me context swithching is high so cpu will be more ideal

[@vaibhavdawra8960]

did you find anything?

[@AbhaySingh-kh2jy]

@@vaibhavdawra8960 time taken for context switching, which is done by kernel (OS) ; ultimately done by CPU will be much less than the time for which a process will keep CPU waiting in case of IO operations, so generally we say considering IO operation case, That in preemptive CPU utilization is higher than non preemptive.

[@vaibhavdawra8960]

TAT-BT would also include time for which process was in waiting queue, while by definition wait time is time process waits in ready queue. Correct me if I am wrong.

[@abhishekkannaujia1096]

I think we have subtracted the time taken only while execution from TAT.....so remaining all will be considered as wait time

[@vaibhavdawra8960]

@@abhishekkannaujia1096 Yes that's the issue I am saying, if you just subtract execution time, it also includes time spent in waiting queue but by definition we should just include time spent in ready queue.

[@abhishekkannaujia1096]

@@vaibhavdawra8960 I think waiting time is not only the time spent in waiting queue. Even in ready queue a processes is waiting for it's chance to get the CPU. So time spent in ready queue will also be counted as waiting time.

Sir amazing video Sir

[@anmoldua9755]

Hi, I have one doubt.. Regarding cpu utilization, both preemtive and non preemtive are using cpu at max??? Isn't it How cpu utilization is more in preemtive scheduling. Can you tell me one scenario where cpu utilization is not been done /compromise in non preemtive..? Other factors like starvation, response time is bad in non preemptive.. But I am confused for cpu utilization?? Kindly explain..

[@abhishekbijalwan3196]

Bro CPU utilization is not just based on how much CPU is being used by a process...it is based on how many processes it is executing like in preemptive scheduling after time quantum expires it start executing another process where as it if process doesn't go for I/O it will keep executing that particular process until it gets terminated. It's like bhai tu 2 sec physics pdh rha h then 2 sec chem pdh rha h to ese me tera mind zyada utilise ho rha h because you are processing two sbjects adjacently.

[@jatingarg1897]

Because of Time Quantum. If the other processes are lined up, after a particular time Quantum, it will go to the waiting state and the other process will start exxecuting. This increases the cpu utilization and decreases the starvation.

[@bite091_jamee7]

thanks bhaiya for this amazing session

[@chandraguptaashoka9890]

In ready queue, If there are 10 process, we can either pick 10th or 1st process. Or can we choose from any position.

[@indianbrave]

It's depend on priority which process is more important

Best explanation

[@ashwinshetgaonkar6329]

Sir regarding CPU utilization in both cases CPU isn't kept idle so both utilize the cpu efficiently

[@shubhangishah5303]

But in fcfs starvation of process occurs while in primitive scheduling every process is given fair share of cpu

[@SaiKrishna-tt6qr]

Why CPU utilization is less in non-premptive when CPU is not idle

Doubt : Sir in Convoy effect , if first process takes 20 units of time, even then after certain time this process time quantum will expire and other process will start executing than how average waiting time will be so much ??
