The physical memory is split into physical pages (akapage frames), which have equal size. Suppose we know that on our system, the number of page frames in the physical memory equals the number of bytes in a page frame. We also know that physical addresses have 28 bits. How many bytes are in a page frame? is split into physical pages (akapage frames), which have equal size.
