In a paged segmented scheme of memory management, the segment table itself must have a page table because
Each segment is spread over a number of pages
Segment tables point to page tables and not to the physical locations of the segment
The processor’s description base register points to a page table
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.
For reference , read below :
Differences or similarities between Segmented paging and Paged segmentation scheme.
This link has slightly different definitions. http://nob.cs.ucdavis.edu/classes/ecs150-2008-02/handouts/memory/mm-segpag.html Which one to follow?
Both are different:
paged segmentation is paging the segment table when it becomes too large.
