| Page size has no impact on internal fragmentation. | |
| Multilevel paging is necessary to support pages of different sizes. | |
| Paging incurs memory overheads. | |
| Paging helps solve the issue of external fragmentation. |
Question 6 Explanation:
- False, Large page size may lead to higher internal fragmentation.
- False, To support pages of different sizes, the Instruction set architecture should support it. Multi-level paging is not necessary.
- True, The page table has to be stored in main memory, which is an overhead.
- True, Paging avoids the external fragmentation.
