OS pagetable

Question

Comments

Given that physical memory is 128 KW and divided into $2^{14}$ frames. Hence Page size or frame size = $2^{13}$

Hence offset bits will be $13$

Now in two level paging each page has $2^{12}$ hence 12 bits each

Hence total length of LAS $= 12+12+13 = 37$ bits

They have given each page table is divided into 2^12 pages but not each page is divided into 2^12 entries.

For outer level 12 bits  is ok, but for inner level how can we take 12 ,we have to take the number of entries each page was divided?
