Handle interrupts, and Control the device d. Control the device, and Manage DMA 35. Which of the following events will cause processes to be created? a. System calls b. Interrupt handling c. System initialization d. System failures ow usually called down and up. Which of the following 36. Dijkstra proposed having two operations on semaphores, n properties must be guaranteed for the two operations? a. Mutual exclusion b. Atomic c. Running in kernel e. Running in background 37. Which of the following process scheduling algorithms may cause the starvation (i.e., some process will never have a chance to run)? a. First-Come, First-Serve b. Shortest job first c. Round-robin d. Fair-Share 38. For decimal virtual addresses 32768, compute the virtual page number and offset for a 4-KB page: a. Page 4, offset 0 b. Page 8, offset 0 c. Page 4, offset 128 d. Page 8, offset 128 39. Suppose that a machine has 40-bit virtual addresses and 32-bit physical addresses. If pages are 1MB, how many entries are in the page table if it has only a single level? 20 a. b. 212 3:0 C. d. 232 40. Consider the page sequence of Fig. 3-15(b). Suppose that the R bits for the pages B through A are 11011011, respectively. Which page will second chance remove? In Fig. 3-15(a) we see pages A through H kept on a linked list and sorted by the time they arrived in memory Page loaded first 0 3 7B12 14 15 18 12 14 15 18 Most reently 18loaded page A is treated llke a newly loaded page a, B b, A c.
