Disk Operating System (specifically) and disk operating system (generically), most often abbreviated as DOS (not to be confused with the DOS family of disk operating systems for the IBM PC compatible platform), refer to operating system software used in most computers that provides the abstraction and management of secondary storage devices and the information on them (e.g., file systems for organizing files of all sorts). Such software is referred to as a disk operating system when the storage devices it manages are made of rotating platters (such as hard disks or floppy disks). In the early days of microcomputing, memory space was often limited, so the disk operating system was an extension of the operating system. This component was only loaded if needed. Otherwise, disk-access would be limited to low-level operations such as reading and writing disks at the sector-level. In some cases, the disk operating system component (or even the operating system) was known as DOS. Source: Wikipedia (http://en.wikipedia.org/wiki/Disk_operating_system)

DOS @ Wikipedia
DOS, short for 'Disk Operating System',[1] is a shorthand term for several closely related operating systems that dominated the IBM PC compatible market between 1981 and 1995, or until about 2000 if one includes the partially DOS-based Microsoft Windows versions Windows 95, 98, and Me. Related systems include MS-DOS, PC-DOS, DR-DOS, FreeDOS, PTS-DOS, ROM-DOS, JM-OS, and several others. In spite of the common usage, none of these...

OpenDOS FAQ list
OpenDOS is a clone of the popular MS-DOS operating system. Like MS-DOS, it is a 16 bit OS, and includes the full range of standard utilities (sort, chkdsk, etc), most of which are improvements over their counterparts supplied with MS-DOS.
