So many utube videos So many tutors But ur way is unique sir Take a bow... ur biggest fan here. Through your videos today i teach my frnds and top my class Thanks a lot .
I have ever seen a teacher like u in my life. U use to clarify the root of topic so clearly that even a weak student can grasp it.Thanks once again!!!!!!
This is really a tough topic but efforts from knowledge gate are really very helpful. Clarity of concepts and easy verification of true and false solutions. Thank you &Keep it up :)
Seriously, Your teaching way is amazing. I came to understand all those topics easily which were quite impossible for me. After watching your different lectures I was unable to stop myself to mention a comment. Thank you so much and please upload other related topics of computer science also.
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)
i am the person who is studying first time bcs i am from electronics background we didnt have OS at that time .Bro. your teaching way with so much energy and one thing is best is you go back and forth and revise all topics in all episode that is best thing .Thank you fully appreciate your hardwork :)
If such type of finest teacher are available on youtube then why we need GATE coaching center. we love you sir . After watching your videos I started to love engineering .

Sir I have seen many of your videos and u make concept look so simple..thank you.. But sir, I have one request, if u can make series of videos on computer architecture and organization. There are very little quality tutorials of this subject on TH-cam especially if GATE is concerned.
Doesn't look like this is mutually exclusive. Assume s = 1. Process P1 call wait(s), evaluates condition of while to false and then preempted before executing s = s -1 Now Process P2 call wait(s), evaluates condition of while to false, executes s = s -1 and goes to critical section and preempted P1 can resume execution from s = s-1 and land in critical section too. Hence, both the processes can access critical section together. Any explanations or something I might be missing here?
@@KNOWLEDGEGATE_kg I think he means to say that the content is very good but but you should switch the audio from mono to stereo, its kind of annoying!

I am not a gate aspirant but it will be really great if you cover the entire operating system and dbms .you explain things really well .
he really deserves a big award, im understanding concepts so welll.thanks sir,have a great life ahead.
really India need teacher's like you sir🙏🙏

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).

these are the best lectures on operating system IPC, i have never seen before.....thank u so much sanchit sir.........
You are a good teacher.Please keep up the good work.Your knowledge will help millions of students.
Nice Explanation. This is the simpler version of the topic that everyone can understand. Thank you so much for making it simple. God Bless you.
something is wrong (or I missed something..) lets consider one use case-> There are 2 processes and context switch happed after while(s
Wait and signal are atomic operations i.e once started they can't be interupted.
So wait will be executed and p2 wont come in between while statement
sir your explaining ability is awasome.
If such type of finest teacher are available on youtube then why we need GATE coaching center. we love you sir . After watching your videos I started to love engineering .

Decrement S
Store S (bas ye wali execute hone se phele hi control kisi or process ke pass chala jaye)

very helpful! Awesome Job. You saved my mid semester exams!
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.
Doesn't look like this is mutually exclusive.
Assume s = 1.
Process P1 call wait(s), evaluates condition of while to false and then preempted before executing s = s -1
Now Process P2 call wait(s), evaluates condition of while to false, executes s = s -1 and goes to critical section and preempted
P1 can resume execution from s = s-1 and land in critical section too.
Hence, both the processes can access critical section together.
Any explanations or something I might be missing here?
I also have the same doubt
Did you got any answer for this
How can semaphore achieve mutual exclusion?(according to the video, not possible)
