# ############## A byte-oriented virtual memory system has the following characteristics. Virtual address: 32 bits Physical address: 36 bits Size of one page: 4 kilobytes The system uses a one-level page table. Each page table entry has three control bits (a valid bit, a referenced bit, and a modified bit) and three access bits (a read bit, a write bit, and an execute bit). The TLB is fully associative and contains 128 slots.

16. Consider the information in Figure 4. How many page frames are present in the system? A) 2^12 frames (4,096 frames) B) 2^16 frames (65,536 frames)

C) 2^20 frames (1,048,576 frames) D) 2^24 frames (16,777,216 frames) E) None of the above.

17. Consider the information in Figure 4. How many page table entries are contained in the page table? A) 2^12 entries (4,096 entries) B) 2^16 entries (65,536 entries)

C) 2^20 entries (1,048,576 entries) D) 2^24 entries (16,777,216 entries) E) None of the above.

18. Consider the information in Figure 4. How many bits does one page table entry contain? A) 26 bits B) 30 bits C) 44 bits D) 50 bits E) None of the above.

19. Consider the information in Figure 4. How many bits does one TLB slot contain? A) 26 bits B) 30 bits C) 44 bits D) 50 bits E) None of the above.

20. Consider the information in Figure 4. Which of the following statements about that virtual memory system is correct? A) It exploits temporal locality, but not spatial locality. B) It requires one 12-bit comparator per TLB slot.

C) It exploits spatial locality, but not temporal locality. D) It requires one 16-bit comparator per TLB slot.

E) It exploits both temporal locality and spatial locality.

Please explain not just answer. Figure 4 is "A byte....128 slots''. It is not a picture
