• Segmentation is similar to Dynamic Partitioning
• Process and memory are divided into unequal-size blocks called
Segment.
• Logical address using segmentation comprises 2 parts, segment
number and offset.
• Differences of Segmentation from Dynamic Partition
• Same process can use spaces of different segments.
• Space allocated to a process can be non-contiguous.
• Segmentation does not suffer from Internal Fragmentation, but still suffer
from External Fragmentation.
• Because the segment size is small, external fragmentation must be less
than that of Dynamic Partitioning.
