Getting started with linux

I. What is Linux?
II. Trying it out
III. Installing
IV. What to do now
V. The Console

Intro:
This tutorial is written with the total Linux n00b in mind.
I've seen too many n00bs get totally left in the dark by asking what
the best distro is. They seem to only get flooded with too many
answers in so short a time. I'm a little bit of a n00b too, so I know
how it feels. I will cover a grand total of two basic distros. You may
learn to strongly prefer other ones (I do!) but this is just to get
you started. I touch on a number of topics that would be impossible to
go into in depth in one tutorial, so I encourage you to actively seek
out more about the concepts I make reference to.

For the last few days, Windows 7 is just about the only OS anyone has been talking about. I figured it was high time for us to share the love and take a look at some other interesting free, downloadable operating systems.
we bring you a collection of 20 that are worth checking out. There are plenty more, so if you’d like to add your favorites, share them in the comments!
