      That's *Indian Bengali* accent which is playing a role here. He is a native speaker of that language.
      p.s: Not every Bengali speaker pronounce that way. I am one of them who don't XD

    The IPT does not solve multiprogramming, it only solves the multi-level size issue. That is, you can still have multi-level table even when using multiple processes: each process will have its PT. What IPT really comes to solve is improving space needed (at cost of a slower search)

    i still dont get one thing... how does the multilevel paging actually help with our problem? it's not like we reduced the size of the total pages, all we did is divide it, and so what? it still takes up the same amount of space in memory. Actually, it takes up more because we waste 1 page for each inner page tables, which could instead have been used to point to an actual frame (instead of another page table). It just seems redundant. I thought i understood the concept wrong when I read my book, so I came to watch a video about it, but i still dont get that. Looks like I'm missing somethinf here

    • @swathid207

      We don't create all the page tables unless there is a process running, so it is using less memory. The worst case is all the processes running and all the page tables being created which never happens ideally. The only caveat is the memory usage for the extra inner page tables which is still better than creating all the combinations of page tables. Let me know if this makes it any clear or we can discuss more :-)

    • @ganeshbelgur5295
      @ganeshbelgur5295 6 ปีที่แล้ว +6

      In a single level page table, the whole page table needs to be in the main memory to access any data in the physical memory. In multi-level paging, out of the 1024 inner page tables only that one particular inner page table (found by using the outer table) is loaded into main memory from the backing store. The rest 1023 inner page tables are not required to be loaded into the main memory now. This reduces memory usage.

    • @MrBsehratmaannking
      @MrBsehratmaannking 6 ปีที่แล้ว +2

      thanks for both of your replies, sorry im replying late. That makes sense that not all of them are loaded, though that does mean every time we want to acces a page table we have to load it from the secondary memory to the main memory.. but i guess that doesn't take too long compared to the amount of space you save in the main memory
