Compare and contrast internal and external fragmentation.
What will be an ideal response?
Internal fragmentation is unused memory that is allocated without ever intending to use it, like when your memory blocks are all 2 KB big. Some processes may only intend to use 1.2 KB, so that 0.8 KB is wasted due to internal fragmentation. External fragmentation, on the other hand, occurs when the free memory is divided into smaller and smaller blocks such that we have small unusable blocks of memory.
