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.

hello! I am new to Linux. I have heard that many companies use Linux in their digital signage players. I am looking for a version of Linux that will allow me to play video on my computer with a simple I/O card input. I am puting on a show at the local theatre, and i need to play a video sequence on demand for one of the scenes. Can anyone point me in the right direction?
Can you explain what you mean by "simple I/O card input" and "digital signage players"?
Sounds like you just need a computer with the ability to play video. There is nothing special about that. Get a computer, install Linux, plug the screen in to the video output, play your video. Is there something I'm missing which means it's more complicated than that?
Do you even need to use Linux? Why not just use any available computer?

Reason: why use Linux?
Well, I dont want to use just any computer. I just want the computer to boot up and then display a black screen until I push a button connected to an I/O card. When I push the button, I want a video clip to play. At the end of the video clip it will return to the black screen. I don't want the computer to do anything else other than that.
An I/O card will allow me to use the computer to control things, like turning on lights and other circuits, as well as controlling the computer with buttons, instead of using a mouse or keyboard.
For instance, I can push a button, (like a doorbell button), and the computer will play a video, and at the same time turn the lights off in the room.
A digital signage player is just a dedicated piece of equipment that plays video either by the push of a button, or on a shedule.
I just want to make my own using a computer because it would be a lot cheaper. If you have ever been to wal-mart, then you know that they have tv screens located in strategic places that inform you of a product or play a commercial about wal-mart's decication to service. I want to achieve the same thing, but just make it so I can push a button, and a video will play.
Preferably, the computer would not need to boot an entire operating system, just play the video. I want to be able to turn on the computer, and it would be ready to play the video after it loads whatever software it needs to do so.
Does that clerify it a little?
I can maybe explain it more if you still don't quite get what i want to do.
This might require programming skills (in some cases), but it certainly can be done.
It's unclear what you mean by "simple I/O card" (custom/home-made device?) and why do you call it "digital signage" (digital signatures are other thing)
You'll need mplayer (or identical video player) and some kind of daemon process which will input from button and will launch mplayer, when button is pressed. In simplest case system won't even need X server.
All you need is that daemon that waits for button signal. If there is ready-to-use software of this kind, then you are lucky. If there isn't something like this, then you'll need to write your own daemon, so programming skills will be required.
Once again, an I/O card (input/output) is a device that you can connect a bunch of wires to. When you touch two wires together, or apply a voltage to them, it will trigger something to happen on your computer. For instance, when you push the power button on your television set, it turns the power on and off.
Digital Signage is more of a Digital Sign. Nothing to do with sgnatures. Typically a television set located in a store advertising a product or promotion, in place of standard cardboard or plastic signs that do nothing else but display one static image or logo. A digital sign can be changed easier than a traditional sign, and often remotely from the internet. Digital signs can gather information from the internet and display it on the screen, such as weather forecasts or stock info. Digital signs are located everywhere from airports, to restaurants, to amusement parks.
If you STILL don't understand, then forget that term altogether, I just want to play a video by pushing a button, external from the computer.
Are you familiar with X-10?
That would be an example of I/O
