Not if you use the so-called "poor man install". Yes otherwise, effectively leaving you with some debian variant. How far it deviates from vanilla debian depends on your install mode (beginner vs debian...).
Is Knoppix decompressed or not after hdd installation?

and if I use Knoppix-installer? is it decompressed?
It is - and will require around 4 Gb HD space.
