Just come across Knoppix by accident and my curiosity takes me here

A little about myself (at least you should know why before you shot me):
during school time - pc does not exist, at least not in my school (i am that old)
I'm a true pc USER - meaning i do not know programming, only use applications .. every thing about pc is self learn thru books, try and error (heartwork) and forums (shot many times cause i asked dumb questions).

My pc .. P3, 933Mhz, 256MRam, using WinME with Opera, Firefox, OO and the likes...

Linux (heard of but never seen before)
Knoppix just heard of it yesterday and boot up once with Knoppix CD and life is never the same again .... I hope ... with your help.

Why, too many things. too many questions ..
Can i ask stupid questions in this forum (I've tried reading a lot of your post and is even more lost)

Q1. will changing settings (e.g. partition, security) while using Knoppix alter any settings in my pc?
Q2. i will read more at the library but there's no book on Knoppix over here? A few good links will be very helpful.
Q3. can i see my pc files while in Knoppix? How?
Q4. any good tips on how to go on from here?

will be back for more if this forum spares my life and give me a life line


many thanks in advance.
