How Is a Process Different from a Daemon in Linux?

Question
How is a process different from a daemon in Linux?

Answer
A process subsumes a daemon. A daemon is a process that runs for a long period of time (e.g., the duration the server is on). It may require no interaction with a user. A logging process or a web service like Nginx are examples of daemons.

This answer was paraphrased from page 34 of The Linux Programming Interface.
