Consider a virtual memory paging system with the following parameters: 2^16 bytes of physical memory; page size of 2^12 bytes; 2^20 pages of logical address space. a) How many bits are in a logical address? b) How many bits in the physical address specify the frame? c) If the system adopts the traditional page table, i.e., each process has a page table, how many entries are in each page table? d) If the system adopts an inverted (hash-table style) page table, how many entries are in the page table
