SEGMENTATION-FRAGMENTATION

• Segmentation cause External fragmentation,when all blocks of free memory are too small to accommodate a segment.
• Solutions:

1.Since segmentation is by dynamic relocation algorithm,we can compact memory whenever we want.
2.Depending on segment size-if the average segment size is small,external fragmentation will also be small.
Because the individual segments are smaller than the overall process,they are more likely to fit in the available memory blocks.
