Least Recently Used (LRU) Explanation

[@VictorChrispinSamson]

I recommend this video to anyone who for the first time, is trying to learn about REPLACEMENT ALGORITHM - FIFO. It's the most simplest video ever here on KZbin, than any other video that i came across. Thank you #TechAcademy

[@stevendong8506]

i saw a lot of videos and yours are the best one, amazing explanation!

[@stanleybane5483]

Madam u saved my semester 💪😁

Engineering must be completed how does it feel

[@Leongreenkiprotich]

​@@Randomvideos-qx2vpand we are just getting started 😅

[@acfromspace]

Great explanation, the highlighting of the numbers and examining page faults were super helpful.

[@mainakghosh906]

most conceptual ...and here in this video the red arrow clear all the confusion about LRU. thank you.

[@Kazatsuyo13]

Thank you so very much. You are far more clearer than my instructor.

Thanks for providing us with a clear understanding, my brain was almost about to explode.

[@fajar13k]

Best explanation i've find in KZbin. Thank you so much

[@ahmetsamiyeniceri]

Is the order of the values ​​we write on the columns important? Because we did it in different way for each one. I'm asking to you cuz you're saying that you understood this well

[@abhirajbais5093]

it was great.understood 3 concepts in just one small video

The reverse Arrow Mark is helpful to understand thank you very much

[@shusilbanjade]

Best Described......... Thanks a ton , man

[@ioanaghita8459]

On column 10 is wrong. We need to change 4. 4 is used once, 2 is used twice and 0 is used 3 times => we change 4 with 3.

[@thorunitha7755]

what is the difference between LRU algorithm and optimal replacement algorithm??

[@bimalgrg8951]

most appreciate your explanation...thank u so much

[@nik_hybrid1442]

Why we don't replace 0 in behalf of 3?

[@SecretswithJA]

Bestest explanation ❤

[@shahnawazansari6440]

ur explanation was clear...thanksssssssssssss

[@ankitabrahmankar8185]

if only the number of pages are given and we are supposed to calculate the number of page faults ..how we do this??

[@raghavsharma3211]

that was very descriptive and well spoken...thanks

[@njoy2075]

crisp and clear thank you

[@paratube7619]

Hi tech académie How used the mfu ?? I would like the answers please

[@hamzamehmud6402]

Thank you for sharing such a brillant video :) helped me alot

[@benjaminmusasizi3777]

Thank you mam for this explanantionn. You are such a sweetheart!!

[@ofgalacticstuff]

I got confused. When you check for LRU digit, how many digits to consider while going left? U took 3 spaces and in one case u took 4 spaces. I don't get it, we have to ignore 0?

[@TechAcademy8]

Ishu D You can consider as many as you need. You need to find which page was inserted in the page frame first. So you check all the pages which are already in the page frame and check when they were inserted, whichever was inserted first is the LRU and you remove it and insert next one when there is a page fault.

[@johandon2882]

I still confuse why u take 4 spaces in one case and 3 for other case..

[@niravsoni2738]

frame size - 1

[@nomanulhaq6601]

elaborate please.i have same query as johan don

[@ernstpierre4068]

I hope it is not too late, the answer to your question is: You will always look backward for current number that are in the 3 frames ( in the case you had a HIT that is mean, the number was already in the memory when the CPU needed it, you don't have any change in the frame numbers , in this case, you can go backward until u find 3 DIFFERENT NUMBER in the queue... Hope this help

[@rina7497]

Clear explanation. Thanks a lot!

[@dakshgulati3966]

Very well explained! Thank you!

[@srinivasb7337]

Excellent explanation

[@Domboy400]

thank u so much...nyc ecplaination..i understood it very well ..so easy:)

[@waynneappollocyzt350]

what is the difference between LFU and LRU

[@οκμπος]

In LFU you take into consideration how many times a page has been used so far (frequency). The one with the lowest frequency gets removed. Note that the frequency gets reset every time you remove it. In LRU you just remove the "oldest" one of the 3. Eg. you add pages 4 then 5 then 8 and you need to add page 6. You remove page 4 since it's the oldest one. It's basically which one was used first between the 3.

[@vaishnaviyerpude29]

Explained very well.

[@gumsumful]

Whats about pseudo LRU??

[@puppy1874]

Thank you, well explained

[@trieule2012]

crystal clear. Thanks a lots

[@rakeshmanna2225]

Hey lru implementation by 2 types, one stack and other count but u only use one ready-made false technic???

[@dushdave8536]

wonderful explanation

[@MegaAvijitdey]

nice explanation

[@hritiksharma5152]

Apke awaz se hme pyar ho gya

[@arghyadip2]

is it optimal replacement...i mean that is that same with optimal replacement or not??

[@ahmetsamiyeniceri]

i've the same question too. I know it's been 2 years but do you know the answer now?

[@tyronskywalker2256]

Thank you so much for this video! :)

[@Gubabis]

Thank you, your explanation was clear and helpfull

[@TheDeftonesmusic]

how will you do this for 2 3 2 1 5 2 4 5 3 2 5 2. here when 2 3 1 are loaded comes 5. so now 1 is most recently used then 2 and then 3.so 3 should be replaced is it correct? there is doubt because again there is a occurence of 2 before 3.so which page should be replaced 2 or 3?

[@swaroopvengali]

Replace 3 by 5

[@tuanphuongtran9956]

TheDeftonesmusic you don't need to replace page 3 because page 2 is already in memory

[@arrjundaas8635]

Awesome explanation

[@ankitagrawal1508]

Nice explanation buddy thanks..

[@khalnayakthecoder]

Best Explanation.....

[@donaldivancribillo8352]

Is it possible that the first 3 page request is the same? Like 7 7 7 0 1 0 4 . . . .?

[@omarsami115]

awesome explanation thank you so much

[@sasa23290]

This is a 3-way associative array. With 2-way associative way and combinations like A B C A B C A, we have hit rate 0 %.

[@jaswanthmopathi8441]

But what is the difference between fifo and lru the logic is the same

[@varmareddy2917]

please explain opt algorithm also

[@ousmanedembele1845]

Very good job mate

[@newalias2851]

You are the best. Thanks a lot!!!!

[@beingdealtwith]

Much appreciated for this.

[@abhishekvashishth557]

It is like fifo isn't, the answer will same by using both method

[@jcq2505]

er....you just stated the disadvantages only....what about the advantages？ Thank you

[@pranitbhoir2167]

if u have program of that can u paste it here

[@randomshii69]

great explanation thanks fr

[@pallabsarkar5765]

Thanks .It was very helpful.

[@nutandevjoshi]

Best explanation, otherwise look at other tutes by others, total goes over the head!

[@ahmetsamiyeniceri]

Is the order of the values ​​we write on the columns important? Because we did it in different way for each one. I'm asking to you cuz you're saying that you understood this well

[@pavan369]

Hello. The explanation is very good. My doubt is - after checking the most recently used, how to follow the order ? how to place pages in the page frame ? In 4th column - you wrote 2 first and then 0 , then 1. Here as per most recently used , 1 should be written first and then 0. In 6th column - you wrote the pages 2 , 0 first and then 3 . Can i write 3 first and later the most recently used pages? Thanks in advance. Waiting for your reply.

[@DilpreetSingh-gh9ss]

Bauht vadia explanation

[@mamjoe18]

clear explanation thanks

[@TechAcademy8]

Welcome :-)

[@subhashisneogi2302]

Thank You,Its very useful

[@leagueoflegendsV]

I think that you made a mistake. You shouldnt switch the 2 on 9th with 3 but with 0 because 0 had no chance and was the oldest until then. Just let me know if I'm wrong.

[@devopstutorials3086]

T q very understanding . 😁
