Your explanation is good ma'am, this example is sufficient for exams, but if someone really wants to know how LRU works then this is the gist: 1. Memory Management Unit has page table. 2. All the pages in the page table form a linked list 3. LRU algorithm requires an extremely fast hardware (obviously expensive), to segregate the pages into most recently used and least recently used pages. This segregation is done in every clock tick or page fault, thus the need for the hardware to be extremely fast. The software implementation of this is known as NFU (Not Frequently Used) which uses an aging algorithm to determine least frequently used page. 4. LRU is said to be extremely efficient but it is also equally difficult to implement, that's why people came up with work arounds.
She's explaining us it's a great thing presentation don't matter if the students are able to understand. as we all know we are very very familiar with her explanation and Don't try to change that familiarity . Hope you don't mind 😁😀 .And we always support Bhanu madam
Thank you mam :: Today July 13 at 10am I'm having OS semester examination I'm learning page replacement clearly from you than my Os mam.. Thanx for it❤❤
Best way to memorize how many digits you look back is by the N frames and UNIQUE values. So, if you have 3 frames, like in the example, you reference the third least recently used unique value to the left. If it's 4 frames, then it's 4th unique value.
Bro actually the last three digits in some case was not least recently so we can then check with more then 3 digits and find out the least recently so she checked 4 digits

Anyone who have no idea of which part of OS is this topic and just come to the part " least recently used" part just cuz it's exam in in 9am here I amwatching this at 2 am
they are same for the most part. consider for example that 2,0,1 are the pages currently in memory and 0 was the 1st to come and 1 was the 2nd and a new page 0 comes. it will be a hit as 0 is already present. now a page 5 comes. in fifo, 0 will be replaced as it was the first to come. however, in lru, 0 will not be replaced since it was the most recent page to be used and we will ignore the initial order of its arrival and replace page 1 which was 2nd to come. hope it helps!!
It's really helpful for us even after 5 year's
The only online resource that could finally explain it in detail! Thank you so much!

Thank you for helping a lot mam , it is midnight and morning i have my sem exam , i understood the concept clearly .
Best greetings from Germany. We love your videos!
Well done maam! Please teach us how to compute for the failure and success ratios. Thanks❤️😊
at 5:24 why we checked with 4 digits to replace? in rest of the algorithm we always check from the last 3 digits before removing...???
Bro actually the last three digits in some case was not least recently so we can then check with more then 3 digits and find out the least recently so she checked 4 digits
How could you understand if the last three digits was not recently used? Pls explain to me
Thaaanks our teacher couldn't explain the logic quite well 10 min here everything was understood
Thank you very much, the video was quite helpful.
Thumbs up. Love from Bangladesh.

very helpful. thank you so much maam
Now I understood completely
why do you sometimes go back 3 digits and sometimes 4 digits?
Yaa bro she had mistake 😂

So what is the difference between FIFO and LRU?. Please explain it
they are same for the most part. consider for example that 2,0,1 are the pages currently in memory and 0 was the 1st to come and 1 was the 2nd and a new page 0 comes. it will be a hit as 0 is already present. now a page 5 comes. in fifo, 0 will be replaced as it was the first to come. however, in lru, 0 will not be replaced since it was the most recent page to be used and we will ignore the initial order of its arrival and replace page 1 which was 2nd to come. hope it helps!!
@@MUmar-tq7pr Thank you.
Here in table,14th column is wrong mam i think bcz the least used is 0 not 2(in column 11)..
no bro you're illiterate
Thank you ma'am ♥️
Mam apne 3 ko replace krne ke liye back in three digit gye the after then 4 ko replace krne ke liye aap 4 digit back gye ?
Awesome 💙🌸
Clean and clear
Helpful👍👍
BRAVO 💪👏
Qué linda 😊
Gud explanation mammmmm....
mam in case of 5 frames should we check 5 numbers before to get least recently used?
Why we r replacing 2 and writing 4 why not 0
Sometimes taking 4 counts sometime 3
yaa....same doubt......
no one asking that question in comments
Thank you! You help me alot :>!!!
Thanks a lot mam ☺️
Good explanation
So helpful video
Thanks a lot Mam.
Thanks a lot
Thankyou so so much 💯
In case of 0,3,0 you took 2 least recently used 4th one
There are duplicates (0) so she looked back a further page because 030 didn't include 2
Nice Mam 😊

Thanks for this video madam
Thank you.
I am unable to understand the difference between FIFO amd LRU.........these are almost same🤔
She has done mistake 😂
Thankyou 🙏
Fantastic mam
Jo hit hota hai usse nhi count karna hai na????
it helped alot thanks
Thank you couldn't get this all understood now
Watching this 10hrs before exam🐽
It's wrong you give both are same FIFO and LRU ans than wt is the diffrence u should take the recently add number☹️
But why our maam writes the first 7 on bottom of the page..
