Consider a pure paging system that uses 32-bit addresses (each of which specifies one byte of memory), contains 128MB of main memory and has a page size of 8KB. a. How many page frames does the system contain (Assume that all of the 128MB memory will be used only for the page frames)? b. How many bits does the system use to maintain the displacement, d? c. How many bits does the system use to maintain the page number, p?
