Answer 2

False

A design change in the structure or semantics of the process control block could affect a number of modules in the OS.

Answer 3

True

We can characterize the behavior of an individual process by listing the sequence of instructions, referred to as a __________, that executes for that process.

A) state
B) trace
C) process block
D) priority

Question 5

All processor designs include a register or set of registers, often known as the program status word, which contains status information.

Question 6

The principal function of the OS is to create, manage, and terminate processes.

Question 7

The OS may create a process on behalf of an application.

Question 8

It is the principal responsibility of the __________ to control the execution of processes.

A) OS
B) process control block
C) memory
D) dispatcher

Question 9

It is not the responsibility of the operating system to control the execution of processes.

Question 10

The process control block is the key tool that enables the OS to support multiple processes and to provide for multiprocessing.

Question 11

A process switch may occur any time that the OS has gained control from the currently running process.

Question 12

The process control block is the least important data structure in an OS.

Question 13

"The process was placed in a suspended state by an agent; either itself, a parent process, or the OS, for the purpose of preventing its execution," is a characteristic of a _________ process.

A) blocked
B) suspended
C) ready
D) swapped

Question 14

For efficiency, applications should be written directly for a given hardware platform.

Question 15

A __________ is a unit of activity characterized by the execution of a sequence of instructions, a current state, and an associated set of system resources.

A) identifier
B) process
C) state
D) kernel

Question 16

The OS may suspend a process if it detects or suspects a problem.

Question 17

If a system does not employ virtual memory each process to be executed must be fully loaded into main memory.

Question 18

A computer platform consists of a collection of hardware resources, such as the processor, main memory, I/O modules, timers, and disk drives.

Question 19

Swapping is not an I/O operation so it will not enhance performance.

Question 20

The first step in designing an OS to control processes is to describe the behavior that we would like the processes to exhibit.

Question 21

The _________ tables provide information about the existence of files, their location on secondary memory, their current status, and other attributes.

Question 22

A _________ is an individual who seizes supervisory control of the system and uses this control to evade auditing and access controls or to suppress audit collection.

A) misfeasor
B) clandestine user
C) masquerader
D) legitimate user

Question 23

When the OS creates a process at the explicit request of another process, the action is referred to as __________ .

Question 24

A total of _________ process states are recognized by the UNIX SVR4 operating system.

A) 3
B) 9
C) 21
D) 15

Question 25

The collection of program, data, stack, and attributes is referred to as the _________ .

A) process structure
B) process control block
C) process location
D) process image

Question 26

A process is in the _________ state when it is in main memory and awaiting an event.

A) Blocked
B) Blocked/Suspend
C) Ready/Suspend
D) Ready

Question 27

A process is in the _________ state when it is in secondary memory and awaiting an event.

Question 28

_________ tables are used to keep track of both main (real) and secondary (virtual) memory.

Question 29

When one process spawns another, the spawned process is referred to as the __________ .

A) trap process
B) child process
C) stack process
D) parent process

Question 30

A process in the _________ state is in main memory and available for execution.

Question 31

The OS must maintain __________ tables to manage processes.

A) process
B) I/O
C) memory
D) file

Question 32

Two essential elements of a process are __________ and a set of data associated with that code.

Question 33

__________ involves moving part or all of a process from main memory to disk.

A) Swapping
B) Relocating
C) Suspending
D) Blocking

Question 34

A significant point about the __________ is that it contains sufficient information so that it is possible to interrupt a running process and later resume execution as if the interruption had not occurred.

Question 35

A __________ is a legitimate user who accesses data, programs, or resources for which such access is not authorized, or who is authorized for such access but misuses his or her privileges.

Question 36

The portion of the operating system that selects the next process to run is called the _________ .

A) trace
B) process control block
C) dispatcher
D) PSW

Question 37

The __________ is a layer of software between the applications and the computer hardware that supports applications and utilities.

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.

A) Blocked
B) Blocked/Suspend
C) Ready
D) Ready/Suspend

Question 39

The _________ is the less-privileged mode.

A) user mode
B) kernel mode
C) system mode
D) control mode

Question 40

The process is said to be operating in a _________ fashion if each process in the queue is given a certain amount of time, in turn, to execute and then returned to the queue, unless blocked.

Question 41

System access threats fall into two general categories: __________ and malicious software.

Question 42

An IDS comprises three logical components: sensors, __________, and user interface.

Question 43

A _________ is an individual who is not authorized to use the computer and who penetrates a system's access controls to exploit a legitimate user's account.

Question 44

A __________ is the maximum amount of time that a process can execute before being interrupted.
