Segmentation with paging

Question

Describe segmentation along with paging?

Answer 1

Segments can be of distinct lengths, so it is harder to discover a place for a segment in memory than a page. Along with segmented virtual memory, we obtain the benefits of virtual memory however we still have to do dynamic storage allocation of physical memory. In order to ignore this, it is possible to combine segmentation and paging into a two-level virtual memory system. Each of the segment descriptor points to page table for that segment. This gives some of the advantages of paging (easy placement) along with some of the advantages of segments (logical division of the program).
