CS 410 Operating SystemsHomework 02
Review Questions (7 pts/ea)2.1 What are three objectives of an OS design?2.2 What is the kernel of an OS?2.3 What is multiprogramming?2.4 What is a process?2.5 How is the execution context of a process used by the OS?2.6 List and briefly explain five storage management responsibilities of a typical OS.2.7 Explain the distinction between a real address and a virtual address.2.8 Describe the round-robin scheduling technique.2.9 Explain the difference between a monolithic kernel and a microkernel.2.10 What is multithreading?2.11 List the key design issues for an SMP operating system.
Problems: (8 pts the first two, 7 points the last one)2.2 An I/O-bound program is one that, if run alone, would spend more time waiting forI/O than using the processor. A processor-bound program is the opposite. Suppose ashort-term scheduling algorithm favors those programs that have used little processortime in the recent past. Explain why this algorithm favors I/O-bound programs andyet does not permanently deny processor time to processor-bound programs.
2.3 Contrast the scheduling policies you might use when trying to optimize a time-sharingsystem with those you would use to optimize a multiprogrammed batch system.
2.4 What is the purpose of system calls, and how do system calls relate to the OS and tothe concept of dual-mode (kernel-mode and user-mode) operation?
