Blocking
When a process is in the _______ state it is in secondary memory but is available for execution as soon as it is loaded into main memory.
Blocked
Blocked/Suspend
Ready
Ready/Suspend
A process is in the _______ state when it is in main memory and awaiting an event.
Blocked
Blocked/Suspend
Ready/Suspend
Ready
The OS must maintain _______ tables to manage processes.

Process location
Process image
The _______ is the less-privileged mode.

3
9
21
15
The portion of the operating system that selects the next process to run is called the _______.
Trace
Process control block
Dispatcher
PSW
A computer platform consists of a collection of hardware resources, such as the processor, main memory, I/O modules, timers, and disk drives.
True
False
For efficiency, applications should be written directly for a given hardware platform.
True
False
A design change in the structure or semantics of the process control block could affect a number of modules in the OS.
True
False
The process control block is the key tool that enables the OS to support multiple processes and to provide for multiprocessing.
True
False
It is not the responsibility of the operating system to control the execution of processes.
True
False
The first step in designing an OS to control processes is to describe the behavior that we would like the processes to exhibit.
True
False
The OS may create a process on behalf of an application.
True
False
Swapping is not an I/O operation so it will not enhance performance.
True
False
If a system does not employ virtual memory each process to be executed must be fully loaded into main memory.
True
False
. A process that is not in main memory is immediately available for execution, regardless of whether or not it is awaiting an event.
True
False
The OS may suspend a process if it detects or suspects a problem.
True
False
All processor designs include a register or set of registers, often known as the program status word, which contains status information.
True
False
The process control block is the least important data structure in an OS.
True
False
A process switch may occur any time that the OS has gained control from the currently running process.
True
False
The principal function of the OS is to create, manage, and terminate processes.
True
False
