daemon
Low (C2)Technical, Literary
Definition
Meaning
A background process in a computer system, or (in Greek mythology) a supernatural being of a nature between gods and humans.
In modern computing, a daemon is a program that runs continuously in the background, performing tasks without direct user interaction. In its classical sense, it refers to a guiding spirit, genius, or inner voice, not necessarily evil.
Linguistics
Semantic Notes
The computing sense is dominant in modern English. The spelling 'daemon' distinguishes the computing sense from the more common and emotive 'demon' (evil spirit). In classical contexts, 'daemon' is neutral or positive, representing a less personified spiritual force.
Dialectal Variation
British vs American Usage
Differences
Spelling: British English more readily uses 'daemon' for the computing term and in classical scholarship. American English sometimes uses 'demon' for the computing sense, though 'daemon' is standard in technical documentation.
Connotations
Similar in both varieties for the technical sense. The classical sense is more likely to be encountered in British academic/literary contexts.
Frequency
More frequent in UK technical writing; in the US, the word is highly specialized and less common in general discourse.

Frequently Asked Questions
No. A daemon is a legitimate, non-malicious background process essential to an operating system's function. A virus is malicious software designed to harm or infiltrate.
It's a reference to Maxwell's demon, a thought experiment in physics. The spelling distinguishes it from the religious/mythological 'demon' and aligns with the classical Greek 'daimon' (neutral spirit).
It is pronounced exactly like 'demon': /ˈdiːmən/. The 'ae' is a digraph representing a long 'e' sound.
It is not recommended unless you are writing for a technical or classical studies audience. In general contexts, use 'background process', 'service', or simply 'demon' (for the mythological being).
