Wanna know more about linux Editions. What I need to install it? and How can I install it?

Lots of great info. Do a search in google.

Try these sites:
http://www.linuxquestions.org/
http://www.linux.org/docs/
http://www.linuxforums.org/

First of all, read documentation

That's better.. Do not install it before you get some level of knowledge, or you have probs

Use links gave by Mischcabob... It will help

If you wonna give Linux a try, i suggest gettin a Live CD, such as Knoppix (http://www.knoppix.org/) , just to get some basic experience

Then get your reading glasses out and read up on different distros and the one which will be best got you
