Answer:
Similarities and differences between demand paged memory management and segmented paged memory management are:
- In demand paged memory, it bring a page into the memory only when it is needed, so there is less I/O & memory needed. On the other hand, segmented paged memory based on common practice by programmer structure their programs in logical group of codes.
- In demand paged, it require the use of high speed direct access storage device that it can directly work with the CPU. Whereas, in segmented paged a program is compile and segment set up according to program’s structural group.
- Demand paging made virtual memory widely used and in segmented paged memory is dynamically allocated.
- Similarities between both demand and segmented paged is that there is a use of job table in both memories .
