27. <9 pts> Given the virtual memory address space of 28bits and 36 bits for physical memory, answer the following:
27.a. ( 3.0 pts) If we use a full array forour page table, as discussed in class, how many entries do weneed?
27.b. ( 3.0 pts) How many bytes of physicalmemory are possible with this memory space?
27.c. ( 3.0 pts) How large is a page tableentry in bits? Do not count the valid bit or any other overheadbits.
