Best answer 54 votes 54 votes Option (B) is true for segmented paging(segment size becomes large so paging done on each segment) which is different from paged segmentation(segment table size becomes large and paging done on segment table) Here option (A) is true , as segment table are sometimes too large to keep in one pages. So, segment table divided into pages. Thus page table for each Segment Table pages are created.

10 votes 10 votes Answer A)Sometiimes segment table are too large to keep in one pages. So, segment table divided into pages. Thus page table for each Segment Table pages are created. B) Segment divided into pages . That is called Segmented Paging http://stackoverflow.com/questions/16643180/differences-or-similarities-between-segmented-paging-and-paged-segmentation C)Yes that is correct , segment table not point to actual location of page table, because segment table is the users view on page table, but it is not the reason for each segment table must have a page table D)Base register points to the page table, i.e. not cause for each segment has separate page table srestha answered Jun 5, 2016 • edited Jun 5, 2016 by srestha srestha comment Share Follow See 1 comment See all 1 1 comment reply Rupendra Choudhary commented Jan 1, 2018 reply Follow Share Hello srestha What do you want to conclude in your option C ? option C is a true statement but not a valid reason for paged segmentation scheme. Segment table entries contains the actual physical address of respective page tables and then those page table entries contains the respective frame number.SEgment table contains the actual physical address because if they contain virtual address then in that way the process will become unnecessary complicated. 1 votes 1 votes Please log in or register to add a comment.
