LRU (Least Recently Used) Page Replacement Algorithm

This video teaches you the LRU (Least Recently Used) Page replacement algorithm

[MrDanielphillis]

how do you determine if a page is used before you determine oldest used page ?
you should mention the concept of page faults as its important to what youre talking about

[melinatziomaka]

Thats what Im tough in my university about the LRU.. :
If we have n page table entries a matrix of n x n bits, initially all zero, is maintained. When a page frame, k, is referenced then all the bits of the k row are set to one and all the bits of the k column are set to zero. At any time the row with the lowest binary value is the row that is the least recently used (where row number = page frame number)

In the description of this video it says LFU instead of LRU.

Dont u think 6th should be striked instead of 4 ?

[DaddyMustache]

I thought the first three iterations would cause a page fault...so wouldn't there be 9 total page faults in this example?

So we need to keep track of a counter for each page for most recent usage?

WHY THERE ISNT A SINGLE EXPLANATION OF LRU IN CLEAR ENGLISH!

[Luan-czuk]

thank you, bro ! It's helps me so much !

[vishaltawede]
