  belief  [syn:  {devil},  {fiend},  {demon},  {daimon}]

  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  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.

  {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).

  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  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).
