1. will knoppix run in a computer with no hdd?

2. can i download anything into knoppix? if yes, how is it possible when the cd is read-only?

3. is there a log or something that records all my tracks. everything from opening a text file to downloaded something?

4. if knoppix records anything at all from what i did, does it erase everything when i boot or take out the cd?

5. does knoppix access my hdd in anyway?
