A daemon (pronounced DEE-muhn) is a program that runs continuously and exists to handle periodic service requests that a computer system expects to receive. The daemon program forwards the requests to other programs (or processes) as appropriate.

A computer daemon is a constantly running program that triggers actions when it receives specific input—for example, a printer daemon spools information when a user decides to print a document. A daemon running on a mail server routes incoming mail to the appropriate mailboxes. Web servers use an “HTTPD” daemon that sends data to users when they access Web pages.
