Question

What is the advantage of segmentation over paging?

Answer 1

Advantages of segmentation over paging:

Speed. Reloading segment registers to change address spaces is much faster than switching page tables.

Segment descriptor tables consume less memory than page tables.

x86 page table entries do not have an 'Executable' bit. With segmentation, you can make a region of memory executable (code) or not (data).

Answer 2

Answer:

Advantages of Segmentation over paging :

1) In segmentation, Procedure and data be distinguished and protected separately. on the other hand, procedure data can not be distinguished and protected separately .

2) In segmentation, changing in data or procedure requires compiling only affected segment not entire program but in paging, change in data or procedure requires compiling entire program.

3)In segmentation, sharing of different procedures are available but in paging, sharing of different procedures are not available.
