Question 6
|
In the context of operating systems, which of the following statements is/are correct with respect to paging?
|
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.
