Chapter 3 – Process Description and Control
True / False Questions:
1. T / F – The principal function of the processor is to execute machine
instructions residing in main memory. 处理器的主要功能是处理驻留在主存中的指令。
ANS: T
2. T / F – A process trace is a listing of the sequence of instructions that execute
for that process. 进程指令追踪就是这个进程的指令序列的列表。
ANS: T
3. T / F – The principal responsibility of the operating system is to control the
execution of processes. 操作系统的主要任务是控制进程的执行。
ANS: T
4. T / F – When one process spawns another, the spawning process is referred to as
the child process and the spawned process is referred to as the parent process. 当
一个进程派生出另一进程时,产生进程的进程是子进程,被产生的进程是父进程。
ANS: F (opposite is true)
5. T / F – Round-Robin processing refers to a method of thread prioritization for
scheduling. 轮转是一种线程优先级调度方法。
ANS: F (not prioritized)
6. T / F – The primary difference between the Two-State Process Model and the Five-
State Process Model is that the latter splits the Running state into two new
states: Ready and Blocked. 两状态处理模型和五状态处理模型主要区别是后者将运行态分割
成就绪和阻塞态。
ANS: F (splits the Not Running state)
7. T / F – One solution to the problem of limited main memory space is swapping,
which involves moving all or part of a process from main memory to secondary
memory. 一种解决主存空间有限的方法是交换,这种交换包括将一个进程的全部或部分从主
存转移到辅存。
ANS: T
8. T / F – In order to define the control structures (e.g., tables) that the O/S
needs to manage processes and resources, it must have access to configuration data
