I'm studying for an exam, and it really helped me understanding the LRU algorithm. But the sound quality is awful! Next time try to record in a less reverberant place.
@lifematch It's cold start. That is, though the first 3 pages didn't replace anything they were never referenced before (so they were not mapped before), so the OS has to call a page fault and pick the first empty page frame..
tanx a lot..dis has realli helped me....iwas breakin ma head tryin to figure out how it works.....atleast im lucky to see dis video jus de day b4 ma main exam :)
Why are you making this more complicated than it is? Why not stack the 'columns' by last access? If you treat the initial row as the MRU (which it is) and the bottom of the 'column' as the LRU, it makes it really easy. Doing it this way removes comparisons across several 'columns', and the need for a different pen.
Again, most helpful!!!
