b. segment peak
c. segment limit
d. segment value
Q. The segment base contains the :
a. starting logical address of the process
b. starting physical address of the segment in memory
c. segment length
d. none of these
Q. The segment limit contains the :
a. starting logical address of the process
b. starting physical address of the segment in memory

d. none of these
Q. The offset ‘d’ of the logical address must be :

b. 14 bits
c. 15 bits
d. 16 bits
Q. A multilevel page table is preferred in comparison to a single level page table for translating virtual address to physical address because :
a. it reduces the memory access time to read or write a memory location
b. it helps to reduce the size of page table needed to implement the virtual address space of a process
c. it is required by the translation look aside buffer
d. it helps to reduce the number of page faults in page replacement algorithms
