Starting to learn Linux.

I would like a web site where I can start to learn more about linux structure. As an operating system.
I don't want to learn how to use it. I want a quick  jump to its depth and details. How it handle memory and processor tasks and standard Input Output I mean from Keyboard to Screen.
Thanks for help.
I have little knowledge of system programming and general programming skills and Operating systems operations.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think one of the best places to find technical documentation for Linux is at

They have a lot of tutorials, but also some really good technical stuff.  There's also an interesting article that I read recently about Linux IPC that might interest you.

Hope this helps,
