daemon /day'mn/ or /dee'mn/ n. [from the mythological meaning, later rationalized as the acronym `Disk And Execution MONitor'] A program that is not invoked explicitly, but lies dormant waiting for some condition(s) to occur. The idea is that the perpetrator of the condition need not be aware that a daemon is lurking (though often a program will commit an action only because it knows that it will implicitly invoke a daemon). For example, under {{ITS}} writing a file on the {LPT} spooler's directory would invoke the spooling daemon, which would then print the file. The advantage is that programs wanting (in this example) files printed need neither compete for access to nor understand any idiosyncrasies of the {LPT}. They simply enter their implicit requests and let the daemon decide what to do with them. Daemons are usually spawned automatically by the system, and may either live forever or be regenerated at intervals. Daemon and {demon} are often used interchangeably, but seem to have distinct connotations. The term `daemon' was introduced to computing by {CTSS} people (who pronounced it /dee'mon/) and used it to refer to what ITS called a {dragon}; the prototype was a program called DAEMON that automatically made tape backups of the file system. Although the meaning and the pronunciation have drifted, we think this glossary reflects current (2000) usage. | |

daemon meaning, later rationalised as the acronym "Disk And Execution MONitor") A program that is not invoked explicitly, but lies dormant waiting for some condition(s) to occur.

They simply enter their implicit requests and let the daemon decide what to do with them. Daemons are usually spawned automatically by the system, and may either live forever or be regenerated at intervals. {Unix} systems run many daemons, chiefly to handle requests for services from other {host}s on a {network}. Most of these are now started as required by a single real daemon, {inetd}, rather than running continuously. Examples are {cron} (local timed command execution), {rshd} (remote command execution), {rlogind} and {telnetd} (remote login), {ftpd}, {nfsd} (file transfer), {lpd} (printing). Daemon and {demon} are often used interchangeably, but seem to have distinct connotations (see {demon}). The term "daemon" was introduced to computing by {CTSS} people (who pronounced it /dee'mon/) and used it to refer to what {ITS} called a {dragon}. [{Jargon File}] (1995-05-11) | |

Daemon the Greek form, rendered "devil" in the Authorized Version of the New Testament. Daemons are spoken of as spiritual beings (Matt. 8:16; 10:1; 12:43-45) at enmity with God, and as having a certain power over man (James 2:19; Rev. 16:14). They recognize our Lord as the Son of God (Matt. 8:20; Luke 4:41). They belong to the number of those angels that "kept not their first estate," "unclean spirits," "fallen angels," the angels of the devil (Matt. 25:41; Rev. 12:7-9). They are the "principalities and powers" against which we must "wrestle" (Eph. 6:12). | |
