Basic Concepts and Fundamentals:
What is Linux?
Linux is an operating system, which can be installed as an alternative to Microsoft Windows or Apple OSX. Linux is free to use, free to change, and you have complete freedom to do whatever you wish with it. Linux is however not a clone in any way of Microsoft Windows. It doesn't natively run Windows software and it works quite differently "under the hood". It will take some time to learn and you may find that some of your hardware isn't well supported by the manufacturer under Linux...but most things are likely to work just fine.
What is a distribution?
For simplicity sake, a distribution is a certain company or groups collection of Linux based software that they have provided to you in an installable package. Each distro is designed to achieve a particular need. Some are meant to be well rounded desktop operating systems supporting tons of hardware configurations, others are meant to be installed on servers only and focus heavily on security, while others are built to be extremely small and fast for older hardware.
Why is this guide written around the Ubuntu distribution? I've chosen Ubuntu as my distribution of choice for this guide as it's a single cd download, it's a pain free install process, it works very well on tons of hardware, and it has great community support. You can visit the Ubuntu forums at Ubuntu Forums
Once you install the Ubuntu operating system, you end up with a fully functional operating system which includes things such as 1). An office suite 2). A graphics application 3). PDF functionality 4). Ability to handle compressed files 5). web browsers 6). instant messaging clients 7). cd burning software 8). games 9). a mail client 10). a bit torrent client and many others. That's right, all this stuff just comes with it. No subsequent installs required...or purchases for that matter.
Where can I get Ubuntu from and what do I need?
You can download Ubuntu from Ubuntu Home Page | Ubuntu. You will want to download the Desktop version. For compatibility sake, I would pick the 32-bit version as that is what I use for this guide. The most recent version is 9.04 and it was released in April of 2009.
When you download Ubuntu (or most any Linux distro), you will download an ISO file. You will need to take a cd burning application and write this image to a cd. Some distros are larger and do require a DVD or multiple cd's.
Also, with Ubuntu, the standard install cd is a LIVE CD. Meaning that you can boot from the CD and see Ubuntu as it will run straight from the cd without having to be installed. Gives you an idea of what to expect and how compatible your hardware is right out of the box.
What is the "Alternate CD" for?: It's primary for low-end computers or boxes which have trouble with the standard install cd.
What's with the different versions, Ubuntu, Kubuntu, Xubuntu, etc?
Essentially, they are the same OS...but they each have a different desktop environment installed. Ubuntu uses Gnome...and is what I suggest for following this guide as that is what I used. Kubuntu uses KDE which is a competing desktop environment to Gnome. Xubuntu uses XFCE which is a low frills light-weight desktop environment suitable for low-end computers or for those who want the fastest possible performance and are willing to give up a few visual things.
Once you pick one, it's simple to just install the other desktop environment if you want to get a feel for how they look. Once you get through this guide, you will just need to install kubuntu-desktop or xubuntu-desktop.
How do i install Ubuntu?
There are multiple ways to install Ubuntu onto your computer. Which method you choose depends upon your comfortability and what you have available. #4 is the method that I would recommend if you already have a computer with Windows that you plan to use...as it's the least risky method possible.
#1). If you have an extra computer lying around, you can simply install Ubuntu onto that computer using the CD.
#2). If you have Windows already installed on your computer, but have left unallocated space on your hard drive, you can boot from the Ubuntu installer CD and then choose to install Ubuntu in that free space and effectively have a dual-boot system
#3). You can install Ubuntu in a virtual machine environment (like VMWare or VirtualBox). You won't be able to experience any of special graphical effects this way, but you have a safe environment to work within without risking any damage to your Windows installation.
#4). You can install Ubuntu using wubi.exe (which is included on your Ubuntu Linux 9.04 cd). If effectively sets you up for a dual boot with Windows, but without having to have partitions available. You simply install Linux like any application within Windows. I've got a post written detailing this procedure here: http://www.xbox360forum.com/forum/co...sing-wubi.html.
The command line (aka The Shell, The Terminal)
People have a "love/hate" relationship with using the command line. I'll let you in on a little secret. Most things can be done either at the command line or in the GUI.
I use the command line quite a bit in my setup guide...and the reason is SIMPLE. You can cut and paste in exactly what I give you and it will work on your computer. Documenting your setup, just cannot get any easier than this. Just trust me on this for the time being, and tell me in the end if you still hate the command line.
What is this sudo thing that starts each command at the command line?
Sudo is the system that is used to elevate your standard user account to temporarily have admin priviledges. When you first installed Ubuntu, the installer configured your user account to be able to use the sudo system.
To use sudo, you simply preface a command with sudo. For example, sudo apt-get install something (this runs apt-get which is the online installer and it is going to install something...and because you started with sudo, it does it with admin level (root) priviledges.
Once you type your command and hit enter, the system will prompt you for YOUR PASSWORD. Once you confirm that you know your password, it will execute that command with admin level privileges for you. It will also cache that credential for a period of time, thus in the next few moments if you keep entering commands, you won't have to type your password each time.
What is root, who is root?
This is the equivalent account to Administrator in Windows. root can do anything and everything on the system. With Ubuntu, you don't really use the root account for anything. Instead, as described above, you use your standard user account and simply preface commands with the sudo command to run with admin level priviledges.
Why should I try out Linux anyway? Is there any real benefit?
Couple of things come to mind.
#1). Linux is free...so if you have a few computers and don't want to spend tons of money on other proprietary systems, this might be a good choice
#2). You are a computer hobbyist and you just want to learn something new.
#3). You want to see what other things are available for your computer. It's often an eye opening experience to see what another operating systems can do. If you never look at the competition, you may just not know what is available.
What types of things won't I have to do or worry about by using Linux
#1). Viruses, or anti-virus software
#2). Spyware/malware/adware: It just doesn't run on Linux and impact the operating system
#3). Registry cleaners: There is no registry to clean, or be concerned with when applications are uninstalled
#4). Defragmenting the hard drive: EXT3 pretty much takes care of itself and fragmentation is hardly an issue.
If I know a command, how do I see instructions about how to use it?
For example, let's say that I want to unzip a file, and I know that the command is unzip...but I don't know what other syntax is required.
type: man unzip
This will then display the "manual" pages to you....or the set of documentation that comes with each command telling you how to use that command.

. But yay for a faster computer. I notice the computer is overall generally faster using Ubuntu 9.04 with ext4 on my notebook. I have to try Debian on ext4 now too
