Beginners Guides: Linux Part 1: Getting Familiar 
Getting started with Linux can seem 
complex, but PCstats walks you through the first steps. Installation not required. - Version 1.0.0
 
Since its creation in 1991 by Linus Torvalds to the present day, Linux has been half operating 
system and half symbol.  This publicly licensed operating system has a sort 
of mystical aura about it that's about as cool as you can get in the computer 
world.  Conquering Linux has been the right of passage for a generation of 
computer enthusiasts.
  Under the skin of this icon lies a mere operating system, but 
it's an operating system with a single  staggering advantage.  It's 
free. Not free as in "gee I hope nobody from Microsoft pokes around inside my computer" 
but 'free' as in the entire core of the operating system must be public 
domain.  
      In this first part of PCstats two-part guide to basic Linux use 
and installation, we aim to familiarize  you with using Linux for everyday computing 
purposes by means  of the most popular Linux desktop environment, KDE.  
     Since we realize 
that many users will not be willing to take the plunge and install Linux onto 
their systems to test it, we will use a 'live CD' Linux distribution, which can 
run entirely off a single CD.  This will allow you to get used to the feel 
and function of the KDE desktop environment, as well as learn some basic Linux 
commands, while avoiding a permanent install.  All you have to do is boot 
from the CD.  Your existing Windows files are left completely intact.  
What's a Desktop Environment?   
Simply put, it's what you see; the Graphical User 
Interface (GUI, pronounced "gooey") of an operating system, like Windows 
has, well… Windows. Microsoft's claim to fame is their graphical desktop 
environment which is an integral part of their operating systems, and of how we 
use computers today. Linux,   on the other hand, was developed first  as 
a non-graphical operating system, an offshoot of Unix. Due to the fact that Linux is 
entirely open source, other programmers are free to create and expand 
upon it.  
             
      Over the years, this 
has resulted in several different 'desktop environments' being available for 
Linux, most of them not surprisingly based on the familiar Microsoft/Apple model 
of a graphical desktop with windows that hold icons representing data.  The 
two desktops that emerged as the most popular are KDE and Gnome, both of which 
are rather similar to Windows in functionality with several small differences 
and refinements.  
These desktop environments, more than any other factor have lead to the increasing popularity 
of Linux. They present  a friendly and familiar face to any 
Windows user (and the fact is, just about every computer user out there is a 
Windows user, sorry Apple), allowing Linux to be used for essential functions without 
frustration or memorization.
