Answer:

  External and Internal Fragmentation
External Fragmentation Internal Fragmentation
It happens when there is wastage in the space, between two assigned units. It happens when the last assigned unit is not filled.

In this, the last page which contains the wasted space is lost, in the case of the page system.

In the case of pure segmentation, some space is always lost due to external fragmentation.

 

Solution: Compaction, paging and segmentation.

Solution: The partition of the memory should be of variable-sized blocks and allocate then the most appropriate block should be allocated.
