What are the differences between MS-DOS and Windows?

Answer 1

Unix usually refers to a family of operating systems that are similar in function or descendants of the original Unix operating system developed at AT&T Bell Laboratories. This includes a large portion of modern operating systems, including:

• All Linux distributions (Red Hat, SuSE, Fedora, Debian, etc.)
• BSDs (FreeBSD, NetBSD, OpenBSD, DragonflyBSD, Mac OS X)
• Solaris
• HP-UX
• AIX

Unix-like systems are multi-user and multiprocessing operating systems; that is, more than one user can be using the machine at one time, and each user can run multiple processes, or programs. The most common way to interact with a Unix-like system is a text command shell, but many users choose to use graphical desktop environments as well.

On the contrary, DOS refers to a family of single-user operating systems first developed for IBM-compatible PCs. Generally, DOS is also single-tasking, meaning that the operating system can only run one program at a time. DOS is not a very modern operating system; a program bug can easily crash the entire computer whereas on modern operating systems (Windows, Mac, Linux, Unix, etc.), program bugs are "caught" by the operating system.

Unix has traditionally been used primarily in server environments, but is also gaining ground as a desktop operating system. Most open source Unix-like operating systems have advanced considerably in terms of user-friendliness. Despite this, Unix's simplicity also means that users are expected to know more, and are generally still more difficult to use than Windows or Mac.

DOS has been mostly replaced by Windows and Mac as PCs. DOS installations still remain today to run older DOS applications, including games to military accounting software.

AnswerDOS is the system that runs your PC. Windows was created as a GUI (graphical user interface) making the running of your computer much easier and safer AnswerUltimately, the difference between these types of programs is who has control over the computer. DOS programs generally expect themselves to be the only program running on your computer, so they will directly manipulate the hardware, such as writing to the disk or displaying graphics on the screen. They may also be dependent on timing, since the computer won't be doing anything else to slow them down. Many games fall into this category.

Windows programs, on the other hand, realize that they must share your computer with other Windows programs. Actually, did you know that Windows 3.x itself is a DOS program? What this means is that Windows has control of the computer's hardware, and in turn it shares parts of the computer's resources with Windows programs. The obvious advantage to this arrangement is that you can do several things at once; for example, you could play Beethoven's 5th, start downloading a file from a BBS, then look at your checking account and use a Calculator to check the balance all at the same time. Another advantage is that you can share data between programs; for example, copying a spreadsheet summary into a work processor document.

The important thing here is that many DOS programs will run poorly or not at all in Windows. For example, if you try to run Microsoft System Diagnostics (MSD) while you are in Windows, you will get the message:

You are running Microsoft Windows.

MSD can only report information specified by it's associated Windows Program Information File (.PIF). Therefore information presented may be less accurate or complete than if MSD is run outside of Windows. For more accurate information please exit Windows and run MSD from the MS-DOS prompt.

Some areas may be affected while MSD is run under Windows: Memory values and types will reflect what Windows provides by itself, and through the associated .PIF file; IRQ values may be reported differently; and the visual memory map in Memory, Memory Block Display, and Memory Browser may show different results. Other areas that may be affected include Video, OS Version, Mouse, Disk Drives, and COM Ports.

So how do you know whether a program is made for DOS or Windows? Nearly all Windows programs bear the Microsoft Windows logo Microsoft Windows compatible, while DOS programs do not. If you're still not sure, try running the program from the DOS prompt first. For example, type calc at a DOS prompt; you will get the message:

This program requires Microsoft Windows.

NOTE for Windows 95/98: if you try running a Windows program from the Windows 95/98 command prompt, the computer will simply start Windows (if it isn't already running) and run the program.

A word of warning for Windows users: in the Main group there is an icon called MS-DOS Prompt. This is not the same thing as running in DOS. It will let you run some DOS programs, such as the command prompt or the EDIT program, but it is still running on top of Windows. The proper way to switch from Windows to DOS is to close or exit all of your Windows programs, including Program Manager.

Windows 95/98

One way to switch the computer from Windows to DOS mode is to click on the Start menu, then Shut Down, then choose "Restart the computer in MS-DOS mode". Doing this will close all Windows programs and (mostly) remove Windows itself from memory.

Another way is to adjust the properties of a DOS program. Right-click on your program (or its shortcut), select Properties, open the Program tab, and click on the Advanced button. In the Advanced Program Settings you can set the program to run in MS-DOS mode, and even specify a starting configuration just for that program.

AnswerMS DOS is in Windows. When you go to shut down, it has a choice. shut down in MS DOS mode. AnswerBasically, both are operatong systems. MS DOS is the oldest OS from Microsoft. It is a single user command line operating system. While Windows (latest version) is multi-user and feature a user friendly GUI(Graphical User Interface). AnswerMS-DOS (MicroSoft Disk Operating System) is a CLI (Command-Line Interface).

Windows is a GUI (Graphical User Interface).

When working with a CLI, you begin with a blank screen and a command prompt. At the command prompt, you type commands, one at a time, for the computer to process. (i.e. "MKDIR C:\MYDIR" to create a directory called "MYDIR" in the root folder of the C drive) Any programs (text editing, database, etc) are run from the command prompt by directing the computer to the location of the program, and typing the execution command.

Example (Text in italics are commands, other text is command prompt.):

C:\> ''CD PROGRAMS''

C:\PROGRAMS\> ''CD GAMES''

C:\PROGRAMS\GAMES\> ''CD PONG''

C:\PROGRAMS\GAMES\PONG\> ''PONG.EXE''

At this point, PONG would take up the entire screen, leaving you unable to do anything but play the game until you exit the game. After you exit the game, you would be brought back to the prompt:

C:\PROGRAMS\GAMES\PONG\>

On the other hand, a GUI offers much more flexibility by using icons and windows to represent objects and programs. With Windows, you can open several different documents or programs, and easily switch between them. Also, there is the Start Menu, from which you can launch program shortcuts instead of having to wade through the entire file directory to execute your choice of program.

The interrelation is that Windows was originally a program ran to top of DOS. In order to use Windows, you used to need a line in your AUTOEXEC.BAT (a script file that automatically executed on DOS startup) that pointed to the Windows program. Windows versions 3.x - 9x and Me still run on top of DOS. What this means is that those versions of Windows aren't really Operating Systems, because they rely on DOS to process all the programs. All those versions of Windows do is make the programs easier to get to and switch between. Windows NT versions, and the Windows XP/2K line are built on their own system kernel so they are considered true Operating Systems on their own.

AnswerDOS was an older version by Microsoft which was entirely text and command based. Windows has a GUI (Graphical User Interface) which means you can use a mouse, view pictures, have icons, etc. If you've ever seen something like '''"c:\>_"''' in white text on a black background, chances are that that was DOS or a version of it.

On Windows XP, you can get a version of it by pressing Start -> All Progs -> Accessories -> Command Prompt. This is an updated version of the original DOS which would run in fullscreen and be the only thing on the computer. You can get started by typing ''HELP '' to see a list of commands. For info on a particular command type '' /?'' .

1. DOS does not supports GUI, Windows supports.
2. DOS does not supports networking, Windows Supports.
3. DOS is a single user OS, Windows is a multi-user OS.
4. DOS is a single tasking OS, Windows is a multi tasking OS.
5. DOS does not supports threading, Windows Supports.
6. DOS supports maximum 2 GB of partition, Windows supports 2 TB or more.
7. DOS supports FAT 16 file system only, Windows supports FAT 32 and NTFS.
8. There is no server support in DOS, Windows has.
9. DOS is not as stable as Windows.

Answer 3

Dos is not stable as windows.dos is single user os but windows is multiuser.dos is single tasking but windows is multitasking.

Dos doesnot support gui.dos is single threading but windows is multi threading.dos doesnot support networking but windows support networking.dos uses fat 16 files system and windows uses fat 32 system.

Answer 4

Unix vs DOS

• Unix is multi-user, DOS is single-user.
• Unix is multi-tasking, DOS is single-tasking.
• Unix supports both CLI and GUI, DOS only supports CLI.
• Unix is an open source, DOS is proprietary.

Unix vs Windows: If we take latest Windows version, almost all the feature are available in Windows which are in Unix but Unix is more robust.

Answer 5

Difference between Unix and Dos is that DOS was designed for single-user systems. Difference between Unix and Windows is that Windows works with GUI environments and Unix and DOS does not.

Answer 6

Microsoft Windows, beginning with 3.0, had a GUI (Graphical User Interface), where MS DOS was purely a command-line prompt.

Answer 7

Yes
