**Daemon** is a process that runs in the background and performs a specified operation at predefined times or in response to certain events.

The term daemon is a [[dido:public:ra:xapend:xapend.a_glossary:u:unix|UNIX]] term, though many other [[dido:public:ra:xapend:xapend.a_glossary:o:os|operating systems]] provide support for daemons, though they're sometimes called other names. Windows, for example, refers to daemons as System Agents and services.

Typical daemon processes include print spoolers, e-mail handlers, and other programs that perform administrative tasks for the operating system. The term comes from Greek mythology, where daemons were guardian spirits.
