MS-DOS and Windows NT are two different operating systems. MS-DOS is a 16-bit, single-user, single-processor operating system that accepts command input from the keyboard. Windows NT is a 32-bit, multi-user, multi-processor operating system that uses a graphical user interface (GUI).
Features of MS-DOS:
16-bit operating system
single-user
Single-processor
Keyboard-based input
Management via prompts and commands
Support for BASIC, C, and other programming languages
Features of Windows NT
32-bit operating system
Multi-user
Multi-processor
GUI
Operation via both mouse and keyboard
Improved safety and durability
Support for the .NET Framework and other technologies
The main differences between the two operating systems are as follows:
Bit length: MS-DOS is a 16-bit operating system, while Windows NT is a 32-bit operating system. This means Windows NT can access more memory and resources.
Number of users: MS-DOS is a single-user operating system, while Windows NT is a multi-user operating system. This means that Windows NT allows multiple users to use the computer at the same time.
Number of processors: MS-DOS is a single-processor operating system, while Windows NT is a multi-processor operating system. This means that Windows NT can use multiple processors at the same time.
Input method: MS-DOS uses keyboard-based input, while Windows NT uses GUI. This means Windows NT allows users to use mice and other graphical input devices.
Security and Stability: Windows NT has better security and stability than MS-DOS. This is because Windows NT is a multi-processor operating system that can handle processes better.
Programming Support: Supports MS-DOS BASIC, C, and other programming languages. Windows NT has support for these languages, as well as support for the .NET Framework and other technologies.

Microsoft Word is a word processing software for creating and editing documents with a graphical interface, while Microsoft DOS is a command-line-based operating system used for file management and running programs. They serve different purposes and have different user interfaces.
Yes, The Sims [The Sims 1, The Sims original, etc...] will run on XP.
A filename is simply a unique identifier for any file... It used to be limited to 11 characters plus a three character extension (for example computer.com) - Advances in programming now allows over 200 characters in a file name.
Differentiate between Command line interface and Menus interface and example of each interaction style
MS-DOS 6.22 has no published minimum requirement! as far as I know. It will work on just about any 8086 IBM Comparable PC with 360kb RAM, Floppy Disk Drive and at least a 10MB Hard Drive! (Versions were released on 3.5" 720kb LD & 5.25" 1.2MB Disks, as well as on RAM Disks, But most if not all versions found today are on 1.44MB HD Disks)and a Mono Display.
DOS is just the operating system just like Windows XP. DOS SHELL is a program in DOS in which you can browse files and open them, etc. Just generally an easier way to move around the DOS operating system
INTERNAL COMMANDS
EXTERNAL COMMANDS
The command CLS clears the screen and resets the location of the command prompt to the top of the screen. This is similar to the Unix command clear.
It's very simple.
Run another user account on computer. Download the software called Malwarebytes. The link is below
Just run a quick scan on your computer, mark all found viruses, delete them then reboot. That's it. You're clean.
Windows is better than DOS in many ways 1. Windows is graphical user interface while DOS is command line interface. 2. Windows has more security than DOS. 3. Windows supports a large number of applications and utilities that are not supported by DOS. 4. Windows is more user friendly and widely accepted. 5. Windows allows easy networking and network mapping. 6. Windows allows interactive troubleshooting. 7. Windows uses hybrid kernel while DOS uses monolithic kernel. 8. Windows (Xp onwards) supports plug and play devices while DOS doesnt. The list is endless.
If you are in DOS, just type C: and hit enter.
It depends on what operating system you are using, but if it's windows XP or windows 2000 do this process:
Start menu --> Run --> Type in "cmd" and press enter -->
If you are using an older version of windows then type "command" in place of "cmd" .
From there it takes a bit of knowledge of the dos system. If you type "help" there is a list of commands you can use. Here are a few basic commands to help you:
If you type in "chdir c:" (stands for change directory) that will bring you to the root of your C drive. From there if you type "dir" (stands for directory) it will list any subfolders and files in which ever directory you are in. To continue into another folder, type "chdir foldername".
If you are deep into the system and wish to only go back a folder at a time, type in "chdir .." instead of the entire address again.
I recommend not deleting any files that you are unfamiliar of because they could be important system files.
MS-DOS is an operating system designed for the IBM PC by Microsoft in 1981. MS DOS is Microsoft Disk Operating System. It was a command-line interface, meaning the user had to type in commands to use it, unlike Windows which is a Graphical User Interface. MS DOS was released on IBM PCs when they came out in the 1980s and continued in popular use until the mid 1990s, by which time the first of the Windows operating systems, Windows 95, began to take over.
MS DOS commands were either stored as individual programs, known as external commands, or in a file called Command.com, which stored more commonly used commands. These were called internal commands. Included in these would have been commands like COPY, DEL, DIR, CD and RD.
COPY enabled the copying of files.
DEL deleted files.
DIR gave a listing of files in a directory (now called a folder).
CD changed from one directory to another.
RD removed a directory.
The command line interface is a throw back to before the Windows GUI was invented and everyone used MS-DOS (late seventies early eighties). You may input MS-DOS commands at the command line interface. For example, click on Start>Run>cmd, this will pull up a black screen at the c:> drive. Type in DIR and it will show you all the Directories. To get out of command line type EXIT. The command line is used when the system has problems and you cannot get to Windows. Then you can copy, delete, or start programs at the command line. If you would like to learn the history and competition between MAC and Microsoft and also learn how Windows came to be, rent the movie "The Pirates of Silicon Valley", its great or visit WOZ.ORG, Steve Woznicaks web site, he invented the personal computer and still answers email. Hope this helps.
Steve Wosniack did not invent the personal computer. TRS80, Commodore, not to mention the altair, the sinclair, Victor and others. Steve did not even invent the GUI or the mouse - this was done by Xerox Palo Alto.. yes that is right Xerox made things easy to use but failed to market it, the same people who gave you ethernet - what you are hooked up to the net with.
Command line functions are many times used for higher level functions and allow people to get to the back end of a program. Sometimes they are there until the GUI can be made for them. Sometimes they are used to allow programmers to do tricks that should not be put into the gui - it keeps the average yo from doing something they should not.
Well, with MS-DOS the user communicates directly to operating system by using a variety of commands that can perform tasks and actions.
MS-Windows is graphical, to navigate the operating system you click different parts such as the taskbar, desktop icons to access certain parts of the operating system.
Intergration: MS-DOS can be accessed through a Windows based operating system by going to 'command promt' or 'CMD.exe'
It depends on what you have set-up for the computer to boot-up. A normal setting is for it to boot from the hardrive or if you are on Linux the setting normally is;
BOOT-UP LINUX
*-Disk Drive
*-USB Ports(sometimes, but not normally)
*-Hard Drive
*-Floppy Disk
DOS is an operating system, so it's leaning towards system software.
In Windows, to bring up the DOS screen, simply go to the start menu, choose RUN, and enter CMD. You can also access the DOS screen from Windows during startup by hitting F8 during the boot process and choosing COMMAND PROMPT.
To get to the command line on your computer click on the Start button, click on Run, then type "cmd" in the run box. You will go to a black box called DOS. You will also see the command line prompt C:>, this is where you type in DOS commands. You can use DOS commands to do just about anything you can do in Windows except it's more work, you can copy, move, del files, etc. To get out of DOS just type Exit at the command prompt. You need to find yourself a book on DOS commands to know how to work it.
Well, there are several ways:
Getting Rid of the Data Physically and Destructively
One, if you don't need the hard drive after the "wipe," is to hammer a nail or two through the unplugged drive, rendering it unreadable to all but the most dedicated data recovery team. If you have an extremely powerful magnet, you could run that over the drive a couple times, too.
Starting Over With a Hard Drive
If you are simply trying to start over with your hard drive, you can use Windows' built-in formatter to erase and reformat the drive. In "My Computer," right-click the drive, select format, use all of the default settings (save for the label of the drive), and hit "Format." This will not work if the hard drive you are trying to wipe is your only or main hard drive, though, and is not completely secure for those of you who are trying to purge data permanently and securely.
If it is your main hard drive, then you can simply reinstall Windows or any other operating system on your computer. This is done by popping in the recovery CD's or installation CD's that most likely came with your computer. Doing this will wipe all data and start you off anew, though the nature of the reinstallation means that this method is about as secure as the previous method (read: not very secure).
Wiping Sensitive Data
One last option, for those of you who want to wipe your drive securely and do not want to reinstall Windows, is to use a third-party program to erase your hard drive for you. The technique that these programs use is to write a large file to your hard drive over and over again to get rid of any residual stored data. These programs will probably cost money, and should really only be used by those who are either selling their current hard drive, and want sensitive data off, or those who really need to remove all traces of their files. To find a program capable of this, Google "Hard Drive Eraser" or "Secure Hard Drive Delete."
One could possibly do the same thing for free by deleting all of the sensitive files by reformatting, reinstalling the OS, or just deleting them in Explorer, and then writing large files to the hard drive until it fills up. This method would rewrite all of the hard drive, and render all of the data almost completely unreadable.
I hope this was helpful. Good Luck!
