I have at least heard of Linux, but recently my physics teacher gave me a copy of Knoppix to look at. I really don't know much about open-source, or anything really in depth about computers for that matter, so I of course have questions.

First, I have the KNoppix English CD version. I have not yet put it into my computer, so I don't know much about what to expect. First question is what do I need to do with my already installed programs? Will I need to reinstall all of them, and can I install all of the same programs? I'm on break from school right now, so it's not a big deal to take the time to put everything back on, but I don't want to lose a program that I'll need come January.

Second, what happens to my existing OS? I have Microsoft XP (I'm wanting better virus protection, which is my my teacher gave me Knoppix.), so do I need to first uninstall everything, or can I just run the Knoppix off of the CD on top of what I have?

Sorry for what must be the most riddiculous and basic questions ever, but I am a total nube when it comes to Linux. Any responses will be appriciated.

Thanks in advance, Chris
