disk operating system
     
         dos the name of a number of operating
        systems which include facilities for storing files on disk.
        such a system must handle physical disk i/o, the mapping of
        file names to disk addresses and protection of files from
        unauthorised access in a multi-user system.
     
        a dos should present a uniform interface to different storage
        device such as floppy disks, hard disks and magnetic
        tape drives.  it may also provide some kind of locking to
        prevent unintentional simultaneous access by two processes to
        the same file or record.

disk operating system
     
         dos the original disk operating system
        from ibm.
     
        dos was the low-end os of choice on the ibm 360, the
        high-end system was called just "os".  dos had a smaller
        kernel and less functionality than os and could run on the
        typical 32k 360/30 and 64k 360/40 class machines.
     
        dos was a successor to tos.
