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 .

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

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 ?

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

I didn't understand what is two semaphore S & Q means here Why process need two semaphore 🤔🤔🤔🤔
@shaziasamreen8584
@shaziasamreen8584 3 жыл бұрын
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
