Answer / subrahmanyam kambala
segmention --> rectifies internal fragmentation
paging scheme--> rectifies external fragmentation
combine the both schemes and eliminates both problems in
managing the memory
paged segmentation
divide program's logical addressspace into one or more segments
maintain a pagetable for each segment
each segment pointer points to page table
segment paging is opposite to above explanation

Answer / p govind rao
PAGING: Paging memory allocation algorithms divide computer
memory into small partitions, and allocates memory using a
page as the smallest building block.
SEGMENTAION: Segmentation means that a part or parts of the
memory will be sealed off from the currently running
process, through the use of hardware registers. If the data
that is about to be read or written to is outside the
permitted address space of that process, a segmentation
fault will result.

Answer / chitra
phisical memory is broken into fixed sized blocks called
frames.logical memory is also broken in to blocks to the
same size called pages.when a process is to be executed
it's pages are loaded in to memory frames.
pages are divided in to 2 parts:
*page number(p)
*page offset(d)
