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.
