And MS-DOS is different than DOS. (DOS was around way back in the day, way before Apple in the 1970's) DOS was created by IBM in 1966.
Sorry I could be very wrong on this. Ever watched the movie Pirates of Silcone Valley? Its the life story of Bill Gates and Steve Jobs. If the movie is true then the following would be correct.
The first program Bill ever wrote was something for his school (this was the time of punch cards and stuff). Him and steve (freinds at this point) then went on this quest to bring the first OS to the computer and started a company. They went thier own ways due to some dispute. Bill then found a guy who had written a Disk Operating System. On a whime and without seeing the software he just went to IBM with the idea. IBM bought it (for a small fortune) and Bill then went a bought DOS from the dude who wrote it (for next to nothing), modified it and tweaked it (not alot though) and gave it to IBM.
The movie also documents the theft, sorry creation of the mouse.
Again Bill heard of it, sold to IBM before getting it himself.
Anyways, a really good movie that I am sure holds some truth. It tells you alot about how Apple Machingtosh came about and Microsoft stole and conned its way in to the world.
DOS (from Disk Operating System) commonly refers to the family of closely related operating systems which dominated the IBM PC compatible market between 1981 and 1995 (or until about 2000, if Windows 9x systems are included): DR-DOS, FreeDOS, MS-DOS, Novell-DOS, OpenDOS, PC-DOS, PTS-DOS, ROM-DOS and several others. They are single user, single task systems. MS-DOS from Microsoft was the most widely used. These operating systems ran on IBM PC type hardware using the Intel x86 CPUs or their compatible cousins from other makers. MS-DOS, inspired by CP/M, is still common today and was the foundation for many of Microsoft's operating systems (from Windows 1.0 through Windows Me). MS-DOS was later used as the foundation for their operating systems.
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. It was the key product in Microsoft's growth from a programming languages company to a diverse software development firm, providing the company with essential revenue and marketing resources. It also provided the platform on which early versions of Windows ran.
People keep saying that Vista is the worst OS in the world because it's full of glitch and so much incompatability software even if they never try it. Why? because other people said it.
I'm still running on Vista and I never, nerver see one software incompatible. For the glitch, Microsoft already correct thoses.
