Chapter 3 – Process Description and Control
TRUE/FALSE QUESTIONS:
T F 1) A computer platform consists of a collection of hardware resources, such as the
processor, main memory, I/O modules, timers, and disk drives.
T F 2) For efficiency, applications should be written directly for a given hardware platform
T F 3) A design change in the structure or semantics of the process control block could aff
a number of modules in the OS.
T F 4) The process control block is the key tool that enables the OS to support multiple
processes and to provide for multiprocessing.
T F 5) It is not the responsibility of the operating system to control the execution of proce
T F 6) The first step in designing an OS to control processes is to describe the behavior th
would like the processes to exhibit.
T F 7) The OS may create a process on behalf of an application.
T F 8) Swapping is not an I/O operation so it will not enhance performance.
,T F 9) If a system does not employ virtual memory each process to be executed must be fu
loaded into main memory.
T F 10) A process that is not in main memory is immediately available for execution, rega
of whether or not it is awaiting an event.
T F 11) The OS may suspend a process if it detects or suspects a problem.
T F 12) All processor designs include a register or set of registers, often known as the pro
status word, which contains status information.
T F 13) The process control block is the least important data structure in an OS.
T F 14) A process switch may occur any time that the OS has gained control from the cur
running process.
T F 15) The principal function of the OS is to create, manage, and terminate processes.
