DOS

DOS /dɒs/, short for "Disk Operating System", is an acronym for several closely related operating systems that dominated the IBM PC compatible market between 1981 and 1995, or until about 2000 including the partially DOS-based Microsoft Windows versions 95, 98, and Millennium Edition.

Related systems include MS-DOS, PC DOS and its ancestor 86-DOS, DR-DOS (including PalmDOS, Novell DOS and OpenDOS), FreeDOS and RxDOS as well as PTS-DOS, ROM-DOS, Embedded DOS, NXDOS and ZDOS.

In spite of the common usage, none of these systems were simply named "DOS" (a name given only to an unrelated IBM mainframe operating system in the 1960s). A number of unrelated, non-x86 microcomputer disk operating systems had "DOS" in their name, and are often referred to simply as "DOS" when discussing machines that use them (e.g. AmigaDOS, AMSDOS, ANDOS, Apple DOS, Atari DOS, Commodore DOS, CSI-DOS, ProDOS, and TRS-DOS). While providing many of the same operating system functions for their respective computer systems, programs running under any one of these operating systems would not run under others.

    Apathy is one of the characteristic responses of any living organism when it is subjected to stimuli too intense or too complicated to cope with. The cure for apathy is comprehension.

    The Enormous Room seems to me to be the book that has nearest approached the mood of reckless adventure in which men will reach the white heat of imagination needed to fuse the soggy disjointed complexity of the industrial life about us into seething fluid of creation. There can be no more playing safe.
