Solution
Segmentation offers better security than paging.So that technique can be used in operating
systems.
PAGING SEGMENTATION
In paging, memory is divided in to
equal size segments called pages
memory segments could vary in size (this is why each
segment is associated with a length attribute).
address space of a process is divided in
to pages of equal size in paging
Sizes of the segments are determined according to the
address space required by a process
paging does not provide such a
mechanism
Segmentation provides security associated with the
segments
Paging is used to get a large linear
address space without having to buy
more physical memory
Segmentation allows programs and data to be broken up
into logically independent address spaces and to aid
sharing and protection.
