In paging all the frames allocated to one program need to be present in the RAM but in segmentation the size of the users can be unlimied. it is a sort of demand pagging in which the page which is to be executed is demended by the scheduler n that page is replaced by any of the page replacement algorithms.

paging-program is divided into pages of equal sizes.It is invisible to the programmer.If virtual memory techniques are used ,not all the pages of a given program need to be in the frames (of main memory) at the same time.

segmentation-program is divided into segments of variable sizes.Only restriction is the maximum size of the segment.It is visible to the programmer.Again virtual memory techniques can be used.

Paging suffers from internal fragmentation, segmentation suffers from external fragmentation

paging is a technic which uses fixed size memory(physical)allocation & segmentation is variable size allocation.paging suffer from internal fragmentation & segmentation is suffer from external fragmentation......

Question in reference to VIDYA VENKITESWARAN's answer...
In what sense do you say segmentation is visible to the user while paging is not. Can you elaborate on it..
Thanks in advance
