An initial bootstrap program is in the form of random-access memory (RAM).
A) True
B) False - (answer)B) False
Google
"Alternatively referred to as bootstrapping, bootloader, or boot program, a
bootstrap loader is a program that resides in the computer's EPROM, ROM, or
another non-volatile memory. It is automatically executed by the processor when
turning on the computer."
In what way is an operating system like a government?
A) It seldom functions correctly.
B) It creates an environment within which other programs can do useful work.
C) It performs most useful functions by itself.
,D) It is always concerned primarily with the individual's needs. - (answer)B) It
creates an environment within which other programs can do useful work.
p4 "An operating system is similar to a government. Like a government, it
performs no useful function by itself. It simply provides an environment within
which other programs can do useful work."
____ operating systems are designed primarily to maximize resource utilization.
A) PC
B) Handheld computer
C) Mainframe
D) Network - (answer)C) Mainframe
The most common secondary storage device is ____.
A) random access memory
B) solid-state disks
C) tape drives
,D) magnetic disk - (answer)D) magnetic disk
p13 "The most common secondary-storage devices are hard-disk drives (HDDs)
and nonvolatile memory (NVM) devices, which provide storage for both programs
and data."
Hard disks, zip disks, and floppy disks are common examples of magnetic disks.
Which of the following would lead you to believe that a given system is an SMP-
type system?
A) Each processor is assigned a specific task.
B) There is a boss-worker relationship between the processors.
C) Each processor performs all tasks within the operating system.
D) None of the above - (answer)C) Each processor performs all tasks within the
operating system.
, p16 "The most common multiprocessor systems use symmetric multiprocessing
(SMP), in which each peer CPU processor performs all tasks, including operating-
system functions and user processes."
A ____ can be used to prevent a user program from never returning control to the
operating system.
A) portal
B) program counter
C) firewall
D) timer - (answer)D) timer
p26 "We must ensure that the operating system maintains control over the CPU.
We cannot allow a user program to get stuck in an infinite loop or to fail to call
system services and never return control to the operating system. To accomplish
this goal, we can use a timer."
Embedded computers typically run on a ____ operating system.
