STUDY QUESTIONS: TEST 1 – FALL 2011 The test covers the review notes from lecture 1; kernel architectures, including the papers on microkernels, extensible architectures, and virtual machines; and selected sections from Chapters 1, 2, 3, and 4 in the text. You will not be responsible for material that was not covered in class, even if it is in the Power Points. Review your homework . The questions highlight important concepts for you to understand. The questions on the test probably won’t look exactly like the ones on the study guide. Introduction/Review Be able to define system call, mode switch, and context switch. Know the purpose of each. Be able to define process. Be able to reproduce the process state transition diagram and describe the characteristics of each state and the kinds of events that cause state transitions. Understand the concept of concurrent execution, on a single processor system and on a multiprocessor. What is the difference between a thread and a process? In what ways are multi-threaded processes “better” than single-threaded processes? What is the difference between a kernel-level thread and a user-level thread? (See Chapter 3 notes for some of this) What is the difference between preemptive and non-preemptive scheduling? What is mutual exclusion and why is it needed? Be able to define deadlock and starvation, and know the difference between them. Virtual memory systems were developed to address what problems? Kernel Architectures
