disk operating system 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}). (1998-07-08) | |

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}. (1999-01-20) | |
