If anyone is confused from the word Semaphore know that in Greek the word Σημαφόρος (Semaphoros) means Signal-bearer. Hope that helps.

This channel is a blessing. During my undergrad, I used to refer to your videos to clear out my doubts. Now doing the same in my postgrad. Why on earth teachers can not teach like this.

Best explaintion of semaphoros on the entire Internet. Thank you so much sir

The point of mutex is to lock a critical section so that it is thread safe but the call for P() itself is not, right? If two processes each read the check for S they will both see that S > 0 and continue to both run S--. How is this accounted for? I dont think the video talked about this specific scenario?

[rohitkandula]

One an only king for Operating Systems🔥🔥🙏🙏

[ashishchawla]

But as the critical section can only be accessed by one process at a time so how two processes are entering the critical section at the same time and using it in counting semaphore?

[dharanyuvi]

Legendary explanation .., thank you champ
