These terms are not guaranteed to refer to the same concept across time but are guaranteed to be consistent within a particular OWL export. Use 'cycAnnot:externalID' for unambiguously referring to a concept across OWL exports or across Cyc inference engines. MS-DOS Operating system of IBM Personal Computers and clones.

MS-DOS UnversionedProgram A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvvhA5pwpEbGdrcN5Y29ycA" class="cyc_term">UnversionedSoftwareObject</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJxiRJwpEbGdrcN5Y29ycA" class="cyc_term">ComputerProgram_CW</a>. The collection of all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJxiRJwpEbGdrcN5Y29ycA" class="cyc_term">ComputerProgram_CW</a> which are &quot;unversioned&quot; in the sense that, strictly speaking, not they, but versions of them, are downloaded, run on a machine, etc. Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvi9EhJwpEbGdrcN5Y29ycA" class="cyc_term">UnversionedProgram</a> are thus highly abstract entities. Positive examples: <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rviFn3pwpEbGdrcN5Y29ycA" class="cyc_term">LinuxKernel_TheProgram</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvuGfGZwpEbGdrcN5Y29ycA" class="cyc_term">Linux_RedHat</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvclthJwpEbGdrcN5Y29ycA" class="cyc_term">WU_FTPD_TheProgram</a>. unversioned program A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJxiRJwpEbGdrcN5Y29ycA" class="cyc_term">ComputerProgram_CW</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViws5wpEbGdrcN5Y29ycA" class="cyc_term">OperatingSystem</a> is a program that provides an environment in which a user can execute instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvyBIVpwpEbGdrcN5Y29ycA" class="cyc_term">ApplicationProgram</a> (q.v.) on the hardware of a computer. That is, running copies of instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViws5wpEbGdrcN5Y29ycA" class="cyc_term">OperatingSystem</a> serve as systems that look for and understand user commands, regulate how system resources are used by application programs, handle the internal operations of computers, and so on. Note that <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViws5wpEbGdrcN5Y29ycA" class="cyc_term">OperatingSystem</a> is disjoint with <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvyBIVpwpEbGdrcN5Y29ycA" class="cyc_term">ApplicationProgram</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwQ499ZwpEbGdrcN5Y29ycA" class="cyc_term">OperatingSystemKernel</a> (q.v.), and that together these three collections partition <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJxiRJwpEbGdrcN5Y29ycA" class="cyc_term">ComputerProgram_CW</a>.
