How power management improves computer performance?
Performance means many different things. Power management is designed to find a good compromise between power consumption (with the aim of reducing power consumption) and computing performance (with the aim of providing sufficiently fast handling of calculations and events). Power management thus improves the computer's performance in terms of battery lifetime.
However, power management algorithms do not simply try to minimize the power consumption by slowing down a computer. Instead, power management algorithms generally try to find a good compromise based on the current demand. Thus, as demand grows, power management might increase the CPU speed, enable more CPU cores or take similar steps to enhance the computing performance (at the expense of increased power consumption).
As long as power management algorithms are allowed to find the best compromise automatically (as opposed to being forced into rigid "minimum power" or "maximum CPU performance" policies), power management algorithms will generally improve the overall computer performance thus.
What is the purpose of use of MS-DOS?
MSDOS was the original operating system for the IBM PC. It has since been replaced in current versions of Windows by a scripting utility, as Windows is now a complete operating system and does not need MSDOS anymore.
What DOS command displays a disk volume label and serial number?
The VOL - DOS command displays the disk volume label and serial number, if they exist. See the related link for more information.
Can MS-Office be installed on MS-DOS?
The modern versions will not work on DOS. The very early versions did, running through the windows environment before Windows became an operating system. These would be versions like Windows 3.1 or Windows 3.11 which you would have found on computers in the early 1990s.

SET is for viewing and changing environment variables as well as storing and manipulating your own variables in batch scripts.
Is it safe to delete tray notifications cache?
No. It is best not to because the computer stores much in caches. Unless the computer is running slow, do not delete. It's safer that way.
What do you think a graphical user interface might be better than a command line interface?
A graphical user interface, commonly abbreviate gui, means there is a visible screen that the user can look at with pictures and such. A command line is just a black background with white typing. There is no mouse or clicking. Its all just code. Go the gui is much easier to use and much more user friendly
What is SAM file and Bat file?
SAM: Security Accounts Manager is a registry file in Windows NT, Windows 2000, Windows XP, Windows Vista and Windows 7. It stores users' passwords in a hashed format (in LM hash and NTLM hash). Since a hash function is one-way, this provides some measure of security for the storage of the passwords.
BAT: Batch File in DOS, OS/2, and Microsoft Windows, is a text file containing a series of commands intended to be executed by the command interpreter. Batch files are useful for running a sequence of executables automatically and are often used to automate repetitive or tedious processes.
How are graphical and command- line users interface different?
graphical interfaces use windows, pictures, checkboxes, buttons which perform functions. Command line is just a textbox, you have to type what you want.
Ok many of the windows 32 files can be infected with viruses they can ruin your computer they will soon make it to the hard drive!! not good you ned to get a good antivirus adware and spyware scanners
Why is a command line interface so fast?

DOS commands are not case sensitive..
dir, Dir, DIr, DIR, dIr, dIR, diR .. all are same..
A DOS device driver is a file that any DOS system will load at startup. They perform many functions, such as memory management, hardware, RAM disks, etc. Most device drivers have a .SYS file extension, and are loaded through a file called CONFIG.SYS. In CONFIG.SYS, a line is added reading DEVICE=driver.SYS to have the driver load.
If you are trying to access a Windows partition on your hard drive, this is not easily possible from DOS. DOS can only read FAT partitions, while modern versions of Windows typically use NTFS. Also, DOS cannot access hard drives on a SATA controller unless the controller is set to "Legacy" or emulation mode.
What is the purpose of commands path in dos?
The path command is an internal command, Syntax
Displays or sets a search path for executable files.
PATH [[drive:]path[;...]]
PATH ;
Type PATH ; to clear all search-path settings and direct Windows to search
only in the current directory.
Type PATH without parameters to display the current path.
Examples
path=c:\windows\command
This is where a lot of DOS commands are stored in Window 95; if you are not able to do a dos command, type this command in, allowing all commands you type in, such as "deltree", to be loaded from this directory. However, if you have another file in another directory such as C:\DOS it will no longer look there.
Additional information
DOS limits the path to 122 bytes. Every command is limited to 127 bytes; however, 127 - 5 (minus 5 because of PATH=) = 122.
Microsoft Windows 2000 and Windows XP users must set or modify their path statement through the environment variables, additional information on how to do this can be found on document CH000549.
