Tampoco ésta es correcta, aunque se le parece ;)

Te iba a decir que era "Disk And Execution MONitor", pero buscando en la wikipedia:

* Daemon - a process in an operating system that runs in the background (Falsely considered an acronym for Disk And Execution MONitor)

According to the original team that introduced the concept, "the use of the word daemon was inspired by the Maxwell's daemon of physics and thermodynamics (an imaginary agent which helped sort molecules of different speeds and worked tirelessly in the background)" [2] (http://ei.cs.vt.edu/~history/Daemon.html). The earliest use appears to have been in the phrase "daemon of Socrates," which meant his "guiding or indwelling spirit; his genius," also a pre-Christian equivalent of the "Guardian Angel," or, alternatively, a demigod (bearing only an etymological connection to the word "demon"). Marshall Kirk McKusick's drawing of a friendly imp (i.e. the BSD mascot) may be viewed as a witty representation of the concept. Thus, a daemon is something that works magically without anyone being much aware of it.
