+# Daemons
+
+A programme that runs in the background, performing a system function. A daemon typically starts at boot or login without having to be specifically launched and keeps running permanently or until manually stopped. 
+
+The custom is for the process name of daemons to end in the letter `d`.
+
+> In the original Greek _daemon_ is translated as 'helper', it doesn't have the medieval connotation of a dark spirit but was used to denote the actions of a god rather than the god itself. A person could have a personal _daemon_ which determines their fate.
