The main difference between fragmentation and segmentation is that the fragmentation is a condition that causes memory blocks to remain unused while segmentation is the technique of dividing a process into several modules or sections. Fragmentation and segmentation are two terms associated with memory management.

Does segmentation cause fragmentation?

Segmented Paging

Main memory is divided into variably-sized segments, which are then divided into smaller fixed-size pages on disk. Each segment contains a page table, and there are multiple page tables per process. ... The process does not cause external fragmentation.

What is the difference between IP segmentation and IP fragmentation?
