Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

When something is running as a Daemon . it means its a program which is running in background & running all the time untill you gracefully stops it.
Now second part... This program which is running in background offers service to whtever it meant for.
e.g. VSFTPD being a daemon, keeps running untill you gracefully stops it or by the time its running it will keep offering you a service of FTP( file transfer protocol) & loging to FTP to use its service.
I'm actually interested in how that term came about for the computer world, anyway. How is it that someone decided to call a service/process that hangs around until you need it a "daemon"? Why not "genie"? Or "attendant"? Or "Succubus"? ;-D

My dictionary defines daemon as "a spirit holding a middle place between gods and men, a good genius". UNIX is God, so it seems pretty appropriate to me. I did hear, many years ago, and probably an urban legend, of a religious organisation who took delivery of a UNIX system but refused to use it when they discovered there were daemons running inside it.
When it boils right down to it though, there truly is no "correct" pronunciation for any word, only a "standard" or generally accepted one, which fluctuates over time. The dictionary in the final analysis does not dictate how a word shall be pronounced, it can only report how it IS being pronounced. Controlling the direction of evolution of the mother tongue is rather like pushing a rope,
There was a time a century or so ago when the generally accepted pronunciation of the word "piano" in my part of the US was "pie-annie", but that edition of the word has fallen into disuse in favor of the more urbane "pee-ann-oh", which in turn probably drives Europeans batty because we Americans do not say pee-ah-no, which is the original pronunciation.
Every spring I have the annual discussion with the wife over whether the flowers called peonies are pronounced "pineys" or the (ahem) CORRECT pronunciation, "pee-oh-nees"
The point is not whether there is a "correct" way to say daemon, but whether in saying it, the idea expressed by it is understood, or whether a competing but similar pronunciation denotes something entirely different. Whether you say "demon" or "daymon", I still know what you are talking about.
