Explain the differences between Paging and segmentation.

Paging and segmentation

Paging

Segmentation

Computer memory is separated into small partitions which are all similar size and considered to as, page frames. Then while a process is loaded this gets divided in pages that are similar size as those earlier frames. The process pages are after that loaded in the frames.

Memory-management scheme which supports user vision of memory.

Computer memory is allocated in different sizes (as segments) depending upon the required for address space through the process.

Address generated through CPU is divided into:

Page number (p) - It used like an index in a page table that contains base address of each page into physical memory.

Page offset (d) - It combined with base address to describe the physical memory address which is sent to the

memory unit.

Logical address contains a two tuple:

< segment-number, offset >

Transparent to programmer (i.e. system

allocates memory)

Includes programmer (i.e. allocates memory to

specific function inside code)
