Dear Sir Greetings from the Doon Valley Plz accept my heartiest congratulations for the great service you are providing to the students' community. I am also a teacher by hobby and take great help from yr videos in helping the students .Right now I am stuck with a confusion over the exact meaning of 'T' used in last while(T) of do while loop in your video explaining the semaphores for process synchronization . Thanking you Sir yours truly J.R.Dora,Dehra Dun)

videos are really very helpful and effective as compared to other videos on youtube. sir plz, upload more and more videos of OS, we have exams.

@manishmaithani398 7 лет назад

Sir, you explained the Semaphore in a very good fashion. But i want to add small point. 1. wait and Signal are system calls and we ensure that there is not interrupt (preemption) while they execute. Means at any time, only one process can execute wait or signal (even many processes are trying to access them). 2. To ensure that we disable interrupt, as int mask = disable() // as the very first line in wait and signal function. (unix OS) 3. And at the end, we restore the interrupt (preemption) restore(mask); // very last line of wait and signal command (unix OS)

@shriram6123 4 года назад

Ye batana 12:00 DOUBT :👀👀👀👁️👁️👁️👁️ ❔❓❔❓❔❔❔❓❔❔ Agar process p1 execute karte time semaphore ko 0 karde par use store na karaye to?? S=S-1 ---> isme teen micro instuction honge na ---> load S Decrement S Store S (bas ye wali execute hone se phele hi control kisi or process ke pass chala jaye) I think is case me ek se jada process ek sath CS me aa jayege or mutual exclusion nahi ho payega.❓❓❓❓❔❔❔
