Problem Statement
Which type of fragmentation occurs when free memory is broken into small pieces and cannot satisfy a process's request even though total free memory is sufficient?
Explanation
External fragmentation happens when the free memory is split into small non-contiguous blocks and so a large request cannot be met although the sum of free memory would suffice. Internal fragmentation is wasted space inside an allocated block. Understanding fragmentation is key to memory management design. :contentReference[oaicite:1]{index=1}
