Question
Problem 1: True/False 1. For I0 devices that receive new data very frequently, it is more efficient to interrupt the CPU than to have the CPU poll the device. Why? O FALSE O TRUE 2. The shortest remaining job first scheduling discipline can lead to starvation. Why? O TRUE O FALSE 3. The elevator algorithm (for disk scheduling) in general leads to lower seek times than the FIFO algorithm. Why? O TRUE O FALSE 4. Two processes communicating via a mailbox could be considered an example of a producer-consumer model of process cooperation. Why? O TRUE O FALSE 5. With SSDS, writing data is straightforward and fast, whereas reading data is complex and slow. Why? O TRUE O FALSE 6. FAT provides slower sequential access to a file than Unix File System. Why? O TRUE O FALSE 7. Adding a TLB may make process context switching slower. Why? O TRUE O FALSE 8. It is not possible to share memory between two processes when using multiple-level page tables. Why? O TRUE O FALSE 9. Round-robin scheduling has always a higher average response time than the shortest job-first. Why? O TRUE O FALSE O TRUE O FALSE 10. One way to respond to thrashing is to kill a process. Why?
