In a system using paged segmentation, the logical address space of each process consists of a maximum of 16 segments, each of which can be up to 64 Kbytes in size. Physical pages are 512 bytes. Determine how many bits are needed to specify each of the quantities below, justifying each of your answers by demonstrating the calculations.
a) Segment number (segment address)
b) Number of a logical page within the segment
c) Displacement within a page
e) Complete logical address

11. In a paged virtual memory system, can the computer 's physical memory address space be larger than a process's virtual memory address space? Explain your answer. (Note: A computer 's "physical memory address space" is the number of bits for the frame number plus the number of bits foir the offset. A process's "virtual memory address space" is the number of bits for a page number plus the number of bits for the offset.)
