41
Q

is used to terminate processes. Those processes can be identified by either name or process ID number (PID). The process can exist on the machine where the administrator is sitting (the default) or on another machine, in which case you signify the other system by using the /S switch. p631

A

TASKKILL Command

42
Q

can be run in Windows 7 or Windows Vista to interact with the Master Boot Record (MBR), boot sector, or Boot Configuration Data (BCD) store. It cannot be used with Windows XP because it uses a different boot structure. p632

A

BOOTREC Command

43
Q

can be used to schedule a shutdown (complete or a restart) locally or remotely. A variety of reasons can be specified and announced to users for the shutdown. p632

A

SHUTDOWN Command

44
Q

is used at the command line to see a list of all the running processes (and their process ID number), similar to what you see in the GUI by using Task Manager. By default, it shows the processes on the current machine, but the /S switch can be used to see the processes on a remote machine. /SVC will show the services hosted in each process and you can use /U if you need to run the command as another user (/P allows you to specify a password associated with that user).p632

A

TASKLIST Command

45
Q

are used to change (or display), make, and remove directories, respectively. p632

A

48
Q

s used to wipe data off disks and prepare them for new use. Before a hard disk can be formatted, it must have partitions created on it. p634

A

FORMAT Command

49
Q

It makes a copy of a file in a second location. (To copy a file and then remove it from its original location, use the MOVE command.) p635

A

COPY Command

50
Q

It’s basically an extension of COPY with one notable exception—it’s designed to copy directories as well as files.p635

A

XCOPY Command

51
Q

is included with Windows 7 and has the big advantage of being able to accept a plethora of specifications and keep NTFS permissions intact in its operations. p636

A

ROBOCOPY Command

52
Q

shows the partitions and lets you manage them on the computer’s hard drives. p636

A

DISKPART Command

53
Q

a command-line-based utility that checks and verifies the versions of system files on your computer. If system files are corrupted, the SFC will replace the corrupted files with correct versions. p636

A

SFC Command

54
Q

can also correct file system problems (such as cross-linked files) and scan for and attempt to repair disk errors. p638

A

CHKDSK Command

55
Q

Actually, if you just type HELP and press Enter, your computer gives you a list of system commands you can type. p638

A

/? Command

56
Q

This centralized database contains environmental settings for various Windows programs. It also contains registration information that details which types of filename extensions are associated with which applications. p639

A

Registry

57
Q

The Registry is broken down into a series of separate areas called what? p639

A

A 
HKEY_CLASSES_ROOT 
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE 
HKEY_USERS
HKEY_CURRENT_USER 
HKEY_CURRENT_CONFIG
59
Q

(ASR) stands for what? p641

A

Automated System Recovery (ASR) which is accessible through the Backup utility, can be used as a last-resort option for system recovery in Windows XP. Both Windows Vista and Windows 7 use the WinRE recovery environment to do a Complete PC Restore to achieve the same goal.

60
Q

Virtual memory uses what’s called? p641

A

swap file, or paging file

61
Q

actually hard drive space into which idle pieces of programs are placed while other active parts of programs are kept in or swapped into main memory. p641

A 
Low
Below Normal 
Normal
 Above Normal 
High

A

Low

69
Q

For applications that don’t need to drop all the way down to Low. This equates to a base priority of 6. p643

A

Below Normal

70
Q

A

Normal

71
Q

For applications that don’t need to boost all the way to High. This equates to a base priority of 10. p643

A

Above Normal

72
Q

A

High

73
Q

Realtime

74
Q
