Question:
Which type of fragmentation occurs when allocated memory blocks are larger than the requested memory size?
Which type of fragmentation occurs when allocated memory blocks are larger than the requested memory size?
Show Hint
The extra space is trapped inside the block, not between blocks.
Updated On: Jul 2, 2026
- External Fragmentation
- Internal Fragmentation
- Page fault
- Segmentation

The Correct Option is B
Solution and Explanation
Step 1: When memory is given out in fixed-size units, a process may need less than a full unit but still gets the whole unit.
Step 2: The leftover space inside the allocated block cannot be used by any other process. This wasted space that sits inside an allocated block is called internal fragmentation.
Step 3: External fragmentation is different. It is free space scattered between allocated blocks, not inside them. A page fault and segmentation are not fragmentation types.
Step 4: Since the block is larger than the request and the extra room is wasted inside it, the answer is (B) Internal Fragmentation.
