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).
Segment size can be byte-granular (size 1 byte to 1Meg in units of 1 byte); pages are always page-granular (size 4K to 4Gig in units of 4K). Segmentation lets you make the segment as large as necessary, with no excess (there is no internal fragmentation).

What are the advantages AND disadvantages of geographic segmentation?
importance of geographic segmentation
What is need of segmentation in image processing?
segmentation is the process of dividing/splitting an image into it's constituent part for analysis purpose...
Why we need image segmentation?
As a simple answer I can say: we do segmentation to separate homogeneous area. IN image processing it can be number of pixels with the same intensity in general.
Why is image segmentation important?
It is important to have image segmentation because it will help when processors are trying to adjust the image quality. They use this to make it a high level image.
What is segmantation?
Divide the memory block into different sizes is called segmentation.
