Deck 14: Windows Operating Systems

Question 1

A replacement paging policy determines which virtual page must be removed from memory to make room for a new page.

Answer 1

True

Question 2

Windows is a non-preemptive multitasking,multithreaded operating system.

Answer 2

False

Question 3

In recent Windows operating systems,almost all low-level I/O operations are asynchronous.

Answer 3

True

Question 4

At the operating system level,file mapping is typically used for file caching,loading,and running executable programs.

Question 5

The I/O Manager allows device drivers and file systems,which it perceives as device drivers,to be loaded dynamically based on the needs of the user.

Question 6

The Open Mode attribute for a file indicates whether other callers can open the file for read,write,or delete operations while this caller is using it.

Question 7

Much of Windows is written in assembly language,a programming language that's standardized and readily available.

Question 8

Multithreading improves database searches because data is retrieved faster when the system has several threads of execution searching an array simultaneously,especially if each thread has its own CPU.

Question 9

To ensure the integrity of the Windows operating system code,the designers separated operating system functions into a privileged executive process and a set of nonprivileged processes called protected subsystems.

Question 10

One disadvantage of Windows is that it does not provide much support for users working in non-English languages.

Question 11

Effective distributed security requires an authentication mechanism that allows a server to prove its identity to a client.

Question 12

Windows XP was the last Windows operating system built on the Windows 95 kernel.

Question 13

LDAP is the hierarchical replicated naming service on which the Internet is built.

Question 14

Before the 1995 release of the Windows 95 operating system,all Windows products were merely graphical user interfaces that required the MS-DOS operating system to perform tasks.

Question 15

Microsoft has recently introduced an optional file system,called a Resilient File System,for handling files with very large data sets.

Question 16

The primary file handling concept in recent versions of Windows is the virtual file.

Question 17

A driver object can only have one device connected to it.

Question 18

Recent Windows operating systems provide distributed security with Kerberos,which provides authentication,data integrity,and data privacy.

Question 19

One of the biggest concerns about Windows operating systems is the need for aggressive patch management to combat the many viruses and worms that target these systems.

Question 20

The lower half of the virtual address space is accessible only to kernel-mode processes.

Question 21

Active Directory groups machines into administrative units called ____.

A) domains
B) sites
C) networks
D) nodes

Question 22

A) Application
B) Virtual
C) Backup
D) Physical

Question 23

By default,a Windows process contains one thread with four components: a unique identifier,the contents of a volatile set of registers indicating state,two stacks used in the thread's execution,and a private storage area used by subsystems and libraries.These components are called the thread's ____.

A) context
B) heap
C) global state
D) environment

Question 24

A) placement
B) replacement
C) fetch
D) paging

A) extensibility,portability,reliability,compatibility,and performance
B) security,portability,reliability,and performance
C) security,expandability,compatibility,and cost-effectiveness
D) portability,interoperability,and performance

Question 26

A) Memory-mapped
B) Virtual memory
C) Virtual system
D) Cached

Question 27

____ provide a high-level interface for passing data between two processes regardless of their locations.

A) Sink caches
B) Named pipes
C) Memory-mapped I/O
D) Mailslots

Question 28

The portion of memory that is used for sections of the kernel that require maximum performance is the ____.

A) resident operating system code
B) system nonpaged pool
C) system paged pool
D) paged user code and data pool

Question 29

The ____ file system can recover from all types of errors including those that occur in critical disk sectors.

A) FAT
B) NTFS
C) CDFS
D) NFST

Question 30

Question 31

Which of the following Windows operating systems integrates cloud environments and distributed access?

A) Windows XP
B) Windows 7
C) Windows 8
D) Windows Server 2012

Question 32

In Windows terminology,the privileged processor mode is called ____ mode and the nonprivileged processor mode is called user mode.

A) server
B) kernel
C) internal
D) computer

Question 33

When opening a file in Windows,the creation of ____ helps bridge the gap between the characteristics of physical devices and directory and file system structures by providing a memory-based representation of shareable physical resources.

A) resource objects
B) file objects
C) file pointers
D) reference pointers

Question 34
