17. Given the logical address 0xAEF9 (in hexadecimal) with a page size of 256 bytes, what is the page offset? A) 0xAE B) 0xF9 C) 0xA D) 0xF900

18. Consider a 32-bit address for a two-level paging system with an 8 KB page size. The outer page table has 1024 entries. How many bits are used to represent the second-level page table? A) 10 B) 8 C) 12 D) 9

21. Assume the value of the base and limit registers are 1200 and 350 respectively. Which of the following addresses is legal? A) 355 B) 1200 C) 1551 D) all of the above

27. What is the context switch time, associated with swapping, if a disk drive with a transfer rate of 2 MB/s is used to swap out part of a program that is 200 KB in size? Assume that no seeks are necessary and that the average latency is 15 ms. The time should reflect only the amount of time necessary to swap out the process.
