stundent starvation for os ends here , indeed such aa gemmm 🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌

1- Semaphores belongs to the non-active waiting solutions for synchronization .
passive waiting solutions : semaphores , locks , cs , monitor .
2 - the solution you discussed , we took it in college as the semaphore form directly .

l enjoyed the tutorial, so insightful and well presented. Thank you!!

[@kwakuboateng7525]

Wowww. Lovely teachings. Do you have a website where I can learn more?. Very well done!! :)

[@VivekRaj-kk5jb]

Please unlock rest of the chapters like deadlock, virtual memory etc. so that we can complete the course.

Hi, you can access them on our website/app after getting the Neso Fuel.

Merci beaucoup.

It is not "need for busy wIting" it should be "overcome the problem of busy waiting".

[@keremaksoy8007]

I think the deadlock is not about only the semaphores with waiting quaes. It can also happens with binary semaphores if we implement them in a same way like in the video, am I right ?

[@kerematasen399]

I guess so.

[@adolfocarrillo248]

No, deadlock can not happen in a binary semaphore, a binary semaphore is like a mutual exclusion algorithm.

[@NisargaChowdaiah]

No, bcz binary semaphores only for 2 processes

Nice sir❣️❣️❣️❣️

This busy waiting for all solution you discussed all have this busy waiting.

[@minhhoangcong9155]

thats what i think

[@unmandarinoalgiorno...9321]

@@minhhoangcong9155 Indeed i didn't understand the waiting-queue solution to resolve busy waiting problem. It seems to me that the busy waiting exists always.

[@Sparkler210]

Deadlock:
Resource1
Assigned to Waiting for
Process1 Process2
Waiting for assigned to
Resource2

I didn't understand what is two semaphore S & Q means here
Why process need two semaphore 🤔🤔🤔🤔

[@shaziasamreen8584]

Each resources has its own semaphore. So think it as P0 is first trying for resource S and P1 is trying for Resource Q.After they get them P0 will wait for Resource Q which is acquired by P1 and P1 will wait for resource S which is acquired by P0 which is a deadlock condition.Hope this helps.Correct me of I am wrong
