¼ , the probability of running in one segment is ½ Ø ¼ . For Ø ¼ , the probability is 0. B. For Ø ¼, we will never get any trial that executes within a single process segment. For Ø ¼, the probability of success is Ô ´ ¼ Øµ ¼, and hence we would expect ¿ Ô ½ ¼ ´ ¼ Øµ trials. For Ø ¾¼ we expect to require 5 trials, while for Ø ¼ we expect 15. Problem 9.8 Solution: [Pg. 476] 730 APPENDIX B. SOLUTIONS TO PRACTICE PROBLEMS This is the UNIX version of the Y2K problem. Some people predict total disaster when the clock wraps around. Just as with Y2K, we believe these fears are unwarranted. This will occur ¾¿½ seconds after January 1, 1970, i.e., on January 19, 2038, at 3:14AM. B.10 Virtual Memory
Problem 10.1 Solution: [Pg. 488] This problem gives you some appreciation for the sizes of different address spaces. At one point in time, a 32-bit address space seemed impossibly large. But now there are database and scientiﬁc applications that need more, and you can expect this trend to continue. At some point in your lifetime, expect to...
