D.O.S. it is an operating system, it is the base for windows. That is incorrect. DOS was not their first product. Their first program was ALTAIR BASIC in 1975. DOS wouldn't come around until the release of the IBM PC in 1981.
End-user retail-all versions of IBM PC DOS (and other OEM-adapted versions) were sold to end users. DR DOS began selling to end users with version 5.0 in July 1990, followed by MS-DOS 5.0 ( in June 1991 ).

DOS 1.x and 2.x: These ancient DOS versions support only the FAT12 file system, used today primarily for floppy disks. If you're still using DOS 1.x or 2.x, man do you need a new computer! :^)DOS 3.x through 6.x: These are more common versions of DOS for older PCs running either straight DOS or Windows 3.x. DOS 6.x was especially popular; millions of copies of these operating systems were sold. DOS 3.x through 6.x support the older FAT12 and the newer FAT16, which was the file system standard for many years in the PC world.DOS 7.0: MS-DOS 6.22 was the last "standalone" version of DOS sold by Microsoft. After DOS6.22, Microsoft sold DOS only as the underpinnings of other operating systems, such as Windows 95/98/ME. The first of these was MS-DOS 7.0, which runs "underneath" the first Windows 95 version (Windows 95A). It supports FAT12, FAT16 and VFAT, the enhanced version of FAT that includes support for long file names.DOS 7.1 and later: These versions of DOS underlie Windows versions from Windows 95 OEM Service Release 2 (Windows 95B) and later. They support FAT12, FAT16, VFAT and FAT32.
