what is MS DOS?mention its functions.?

Answer 1

MS-DOS (short for Microsoft Disk Operating System) is an operating system commercialized by Microsoft. It was the most commonly used member of the DOS family of operating systems and was the dominant operating system for the PC compatible platform during the 1980s. It has gradually been replaced on consumer desktop computers by various generations of the Windows operating system.
MS-DOS was originally released in 1981 and had eight major versions released before Microsoft stopped development in 2000.

Windows NT, although not based on DOS, provides a command-line interface similar to MS-DOS's character-mode interface. This command line is provided by a native executable, cmd.exe. Many command-line applications (known as console applications) for Windows are incorrectly referred to as DOS applications, when actually they are full Windows applications which use the console for their output rather than a graphical interface, and cannot be run under any version of MS-DOS.

Windows NT can run MS-DOS programs through the use of the NTVDM (NT Virtual DOS Machine), and the 16-bit command.com interpreter from MS-DOS 5.0 is still included to maintain application compatibility with programs that expect it (This is illustrated by the output produced by the command "command.com /k ver", which displays "MS-DOS Version 5.00.500" in the console window). The command "ver" returns the string "Microsoft(R) Windows DOS" when executed under command.com, but "Microsoft Windows XP [Version 5.1.2600]" (or similar depending on the version of NT) when run from cmd.exe.

Recent versions of NT for x64 architectures, including Windows XP Professional x64 Edition, Windows Server 2003 x64 and Windows Vista x64, no longer include the NTVDM and can therefore no longer natively run MS-DOS (or 16-bit Windows) applications. For MS-DOS and Windows 3.11 or earlier programs, however, there exist alternatives in the form of emulators such as Microsoft's own Virtual PC, VMWare, Bochs, DOSBox, etc.

That means Now days MS dos dont have much functions..

MS-DOS was Micro$oft's first OS. I believe they bought parts of it from IBM or some other company, but through some shrewd moves got computer mfgrs to use it - I think they gave it away, at least at the beginning. MS-DOS essentially killed the many other OSes that existed at the time (and which were pretty much incompatible).

WIndoze 3.x was a GUI shell but MS-DOS was the core. Later versions of Windoze moved away from MS-DOS, keeping only portions of it's functionality.

MS-DOS probably took parts of CP/M and other OSes at the time (there are some common commands).

I recall some versions of MS-DOS having mouse capability, but I don't have a copy lying about, so can't say for sure, and I am not going to do the google search to answer that one!

MS-DOS was fast, powerful, and required that you know the various commands you wanted to perform - no simple point and click and icons to protect users from the "command line" and many people hated it!
