Q. Why page sizes always powers of 2?
Answer: Recall that paging is executed by breaking up an address into a page and offset number. It is most competent to break the address into X page bits and Y offset bits rather than perform arithmetic on the address to compute the page number and offset. For the reason that each bit position represents a power of 2 splitting an address between bits results in a page size that is a power of 2.
