From The Jargon File (version 4.4.7, 29 Dec 2003) :
1. Often used equivalently to daemon ? especially in the Unix world,
where the latter spelling and pronunciation is considered mildly archaic.
2. [MIT; now probably obsolete] A portion of a program that is not invoked
explicitly, but that lies dormant waiting for some condition(s) to occur.
See daemon. The distinction is that demons are usually processes within a
program, while daemons are usually programs running on an operating system.
Demons in sense 2 are particularly common in AI programs. For example, a
knowledge-manipulation program might implement inference rules as demons.
Whenever a new piece of knowledge was added, various demons would activate
(which demons depends on the particular piece of data) and would create
additional pieces of knowledge by applying their respective inference rules
to the original piece. These new pieces could in turn activate more demons
as the inferences filtered down through chains of logic. Meanwhile, the
main program could continue with whatever its primary task was.

1. (Often used equivalently to daemon,
especially in the Unix world, where the latter spelling and

part of a program which is not invoked explicitly, but that

At MIT they use "demon" for part of a program and "daemon"
for an operating system process.
Demons (parts of programs) are particularly common in AI

The use of this term may derive from "Maxwell's Demons" -
minute beings which can reverse the normal flow of heat from a
hot body to a cold body by only allowing fast moving molecules
to go from the cold body to the hot one and slow molecules
from hot to cold. The solution to this apparent thermodynamic
paradox is that the demons would require an external supply of
energy to do their work and it is only in the absence of such
a supply that heat must necessarily flow from hot to cold.
Walt Bunch believes the term comes from the demons in Oliver
Selfridge's paper "Pandemonium", MIT 1958, which was named
after the capital of Hell in Milton's "Paradise Lost".
Selfridge likened neural cells firing in response to input
patterns to the chaos of millions of demons shrieking in
