First of all, how to find size of virtual memory? And what about the statement: The page table is divided into 8k pages each of size 16KB What can you interpret about the statement? Are they referring to innermost page table or outermost? 0 votes 0 votes santhoshdevulapally commented Jan 18, 2017 reply Follow Share Each level having 8K pages and page size=16KB. No of pages in outer level=No of pages in inner level=8K. 0 votes 0 votes Sushant Gokhale commented Jan 18, 2017 reply Follow Share That would answer in Megabytes. 0 votes 0 votes santhoshdevulapally commented Jan 18, 2017 reply Follow Share outer page table size=No of pages*PTE =8K*4B =32KB. 0 votes 0 votes Sushant Gokhale commented Jan 19, 2017 reply Follow Share it should be #pages * page size 0 votes 0 votes santhoshdevulapally commented Jan 19, 2017 reply Follow Share Page table size=No of pages*PTE. //PTE= no of entries in a page of page table.. not page size. 0 votes 0 votes Sushant Gokhale commented Jan 19, 2017 reply Follow Share But they have given page size, right? Also you have assumed PTE = 4B. How, can the #page table entries = 4B ? :) 0 votes 0 votes Rahul Jain25 commented Jan 19, 2017 reply Follow Share @sushant page table size=no of entries×PTE And here what they want to say is that a single level page is divided into 8K pages and 2 level paging is implemented. So we 8k entries in outer level and each of 32 bit which gives 32KB But when I tried to calculate inner page table I couldn't match any options I tried frame size as 4KB as well as 16KB. And moreover I don't think page and frame size could be different. Even if possible options are not matching for inner table for me. 0 votes 0 votes Please log in or register to add a comment.
