Segmented page allocation is a type of memory management that uses base and bound registers to determine memory faults, similar to dynamic page allocation. More importantly it is different to dynamic page allocation since the entire process doesn't have to be in memory, similar to using virtual memory paging where the program is broken into pieces. Unlike virtual memory paging, the maximum virtual memory size is limited to the size of physical memory.

Why are segmentation and paging sometimes combined into one scheme?
Segments can be of different lengths, so it is harder to find a place for a segment in memory than a page. With segmented virtual memory, we get the benefits of virtual memory but we still have to do dynamic storage allocation of physical memory. In order to avoid this, it is possible to combine segmentation andpaging into a two-level virtual memory system. Each segment descriptor points to page table for that segment.This give some of the advantages of paging (easy placement) with some of the advantages of segments (logical division of the program). ok hope wil b helfill
Is a starfish segmented?
Yes, a starfish is segmented into arms or rays, which radiate out from a central disc. Each arm contains intricate structures that help the starfish move, sense its environment, and capture prey.
