What is a Daemon?
A daemon is a method that detaches itself from the terminal and runs, disconnected, in the background, waiting for requests and responding to them. It can also be explained as the background process that does not belong to a terminal session. Many system functions are commonly performed by daemons, including the send mail daemon, which handles mail, and the NNTP daemon, which handles USENET news. Many other daemons may exist.
Some of the most common daemons are:
init: Takes over the basic running of the system when the kernel has finished the boot process.
inetd: Responsible for starting network services that do not have their own stand-alone daemons. For instance, inetd usually takes care of incoming rlogin, telnet, and ftp connections.
cron: Responsible for running repetitive tasks on a regular schedule.
