Deck 1: Introducing Operating Systems

Question 1

The Device Manager is responsible for connecting with every device that's available on the system and for choosing the most efficient way to allocate them.

Answer 1

True

Question 2

The central processing unit (CPU)is the brains of the computer with the circuitry to control the interpretation and execution of instructions.

Answer 2

True

Question 3

General-purpose operating systems such as Linux or Windows are used in embedded systems.

Answer 3

False

Question 4

The content of a random access memory (RAM)chip is nonvolatile,meaning that it is not erased when the power is turned off.

Question 5

In the 1980s,as a result of multiprocessing techniques,it became possible to execute two programs at the same time in parallel.

Question 6

Networking was not always an integral part of operating systems.

Question 7

Onboard systems are computers that are physically placed inside the products that they operate to add features and capabilities.

Question 8

When executing a job,the File Manager determines whether a user request requires that a file be retrieved from storage or whether it is already in memory.

Question 9

The Memory Manager,the Interface Manager,the User Manager,and the File Manager are the four essential managers of every major operating system.

Question 10

The Memory Manager is in charge of main memory,widely known as ROM.

Question 11

The buffers used in the 1950s to reduce the discrepancy in speed between the I/O and the CPU were conceptually similar to those now used routinely by Web browsers to make video and audio playback smoother.

Question 12

In active multiprogramming schemes,a job can monopolize the CPU for a long time while all other jobs waited.

Question 13

Batch systems date from early computers,when each job consisted of a stack of chips entered into the system as a unit known as a stack.

Question 14

The first bug was a moth trapped in a Harvard computer.

Question 15

In the 2010s,chips with millions of transistors that were very close together helped increase system performance dramatically.

Question 16

An important function of the Processor Manager is to keep track of the status of each job,process,and thread.

Question 17

Operating systems with networking capability have a fifth essential manager called the Network Manager that provides a convenient way for authorized users to share resources.

Question 18

With distributed operating systems,users need to be aware of which processor is actually running their applications.

Question 19

The operating system manages each and every piece of hardware and software.

Question 20

There are two primary types of user interfaces: the graphical user interface and the command line interface.

Question 21

In active multiprogramming,each program is allowed to use only a preset amount of CPU time before it is interrupted so another job can begin its execution.The interrupted job resumes execution at some later time.This idea is called ____.

A) shared processing
B) CPU sharing
C) time slicing
D) distributed processing

Question 22

Starting in the 1950s,to reduce the discrepancy in speed between the I/O and the CPU,an interface called the ____ was placed between them to act as a buffer.

A) control unit
B) scheduler
C) holder
D) buffer manager

Question 23

With the development of ____ technology,a single chip was equipped with two or more processor cores.

A) multiprogramming
B) multimedia
C) networking
D) multicore

Question 24

The ____ is often very different from one operating system to the next,sometimes even between different versions of the same operating system.

A) User Interface
B) Process Manager
C) Memory Manager
D) File Manager

Question 25

____ allows separate partitions of a single server to support different operating systems.

A) Multiprocessing
B) Multithreading
C) Virtualization
D) Shared processing

Question 26

There are two types of real-time systems depending on the consequences of missing the deadline.A ____ real-time system risks total system failure if the predicted time deadline is missed.

A) constrained
B) restricted
C) soft
D) hard

Question 27

The efficiency of a batch system is measured in ____,which is the number of jobs completed in a given amount of time.

A) processes
B) threads
C) throughput
D) turnaround time

Question 28

____ is where the data and instructions of a computer must reside to be processed.

A) CPU
B) Main memory
C) Read-only memory
D) I/O memory

Question 29

The name for the core portion of an operating system is the ____.

A) manager
B) center
C) nucleus
D) kernel

Question 30

The ____ uniquely identifies each resource,starts its operation,monitors its progress,and,finally,deallocates it,making the operating system available to the next waiting process.

A) Device Manager
B) File Manager
C) Keyboard Manager
D) Memory Manager

Question 31

A ____ chip holds software that is used to start the computer.

A) RAM
B) ROM
C) CPU
D) buffer

Question 32

____ systems are used in time-critical environments where reliability is key and data must be processed within a strict time limit.

A) Embedded
B) Hybrid
C) Interactive
D) Real-time

Question 33

A system with ____ divides programs into parts and keep them in secondary storage,bringing each part into memory only as it is needed.

A) virtual memory
B) shared memory
C) segmented processing
D) passive multiprogramming

Question 34

____ is the practice of using Internet-connected resources to perform processing,storage,or other operations.

A) Cloud computing
B) Command line interfacing
C) Process management
D) Network management

Question 35

A hybrid system is a combination of ____ systems.

A) batch and interactive
B) batch and real-time
C) interactive and real-time
D) real-time and general-purpose

Question 36

The word ____ is used to indicate that a program is permanently held in ROM (read only memory),as opposed to being held in secondary storage.

A) hardware
B) firmware
C) software
D) shareware

Question 37

Each peripheral device has its own software,called a(n)____,which contains the detailed instructions required to start that device,allocate it to a job,use the device correctly,and deallocate it when it's appropriate.

A) device controller
B) device software
C) device handler
D) device driver

Question 38
