This post uploaded 5 years ago is helping me now. Lot thanks for you mam🎉
Actually, I was confused with the LRU replacement algorithm before watching this video
your trick really helped me to understand the concept. thank you, mam...
I hav good marks in os thanks to u...🥳🥳
Best ever, Crystal n clear explanation on OPT scheme...Loved it. Thanks a lot.
this is the best teacher on youtube...am a computer science student in Uganda and madam Jenny is practically my lecturer...coz she is the best av seen....Thanks for all the work you have done...much love.
I can't express how well you explained it, it was so easy to digest after watching other videos I came here...thanks a lot
Mam... Thank you so much from Bangladesh 🇧🇩. Iam a 5th semester CSE student now. I start follow your valuable tutorial when I am 3rd semester for the subject Data structure. In 4th semester I follow your tutorial for computer Algorithm and Now 5th Semester follow for Operating system.Iam very Happy and satisfy to follow your tutorial and doing very good result to exam. Pray for me Mam after finish my study I got a good Job..
i came here 3 times already and finally understand. thankyou very much!!!
Thankyou so much mam your concept are easily understandable. I'm the type of student who start studying a day before exam😅😅but now i can prepare whole syllabus in a day with your lecture. Thank you once again for teaching in very easy way it really helped much.

I am very very very thankful to u mam u helped me a lot to known the subject. Which I have ignored listening the classes but by ignoring I have got ur channel that is so nice thing to me mam.
Good Lecture.
I am now able to understand LRU, Optimal Page Fault.
Nice video. thanks for this video
That’s the best explanation I could found. Thank you 🙏
many students are benefited from this channel especially to sem exams. we are not relying on our noob lectures anymore..also job of getting bucket to teacher is resolved..😉😉😉😉
heyy do you want my handwritten Operating system notes?? I am selling it at a low price
If only i had found this video a year ago 😢😢. I would have passed the exam by now. Still tho. Thank you very much. You are a better teacher than those in my university that's for sure
Pehli baar mujhe lru samaj mai aaya.Very nicely explain👏👏👏

As always, great explanation, you make it very simple to understand. A small feedback, as a suggestion you could place the whiteboard to the right so you don't obstruct visibility while explaining .
Super mem i impressed with you and your teaching style. I always confused among these algorithm. Many many thanks to you.
Love the way you teach
I am now able to understand LRU, Optimal Page Fault.
Nice lecture . thank u so much ma'am u r good teacher in this world... " I'm from pakistan"

Our OS teacher will not teach like this... She wont use the chalk and board to teach , she will just display something in the screen.. And blabouring something else... 😐 , But ur really great teacher Jenny sis..🤗
Hello Mam, i have a doubt regarding DFS algorithm is that....suppose we have to find route between two nodes means starting node and the node where we have to reach has been mentioned.
And as per your lectures i can create a simple straight route in the graph.
Well, my question is that mam do we have to visit all of the nodes? Do we have to insert all of the nodes eventually into the stack or we can ignore some nodes in that case....Please respond.
Thanks mam you can solve my problem list recently algorithm thank you so much
Hi mam you taught very well I am waiting your all video it's very useful for net preparation kindly post more videos

Thank you so much for your help mam tomorrow is my os exam .u have helped me a lot mam
ma'am can you please do a video on Second - chance (clock) Page - replacement algorithm and Enhanced Second- Chance Algorithm, that topics is after this but for reason it looks you skipped it. Your videos are amazing and very helpful please consider this . Thank you very much.
14:25 since it is almost impossible to implement, can it be used in live streaming videos?
The thing is....
U r not only teaching.....

They are teaching this first half-year in university in Germany, and I could puke seeing "teachers" pulling out masses of actual code or formulas to explain this to newcomers. You used lenguage and an easy to overlook table and that is exactly the right way
