1. Is it necessary to have the page size be a power of 2? Could a page of size, say, 4000 bytes be implemented in theory? If so, would it be practical?
2. A virtual memory has a page size of 1024 words, eight virtual pages, and four physical page frames. The page table is as follows:
|

a. Make a list of all virtual addresses that will cause page faults.
b. What are the physical addresses for 0, 3728, 1023, 1024, 1025, 7800, and 4096?
