Question

What are some of the design issues for paging systems?
i. If a local page replacement algorithm is used and the working set grows, thrashing will result; if a global algorithm is used, it may be possible to start each process up with some number of pages proportional to the process’ size, but the allocation has to be updated dynamically as the process runs
ii. Even with the best page replacement algorithm and optimal global allocation, it can happen that the system thrashes – when the combined working sets of all processes exceed the capacity of memory.
iii. Determining the best page size requires balancing several competing factors
iv. Locking pages in memory

Explanation / Answer

Option A is right answer
Suitable for Design Issues of Paging System
->Local vs Global Allocation Policies
->Page size

iv is wont come in design issue, i.e locking pages in memory Comes under The Implementation Issue.
