32 bit vs 64 bit versions?

[abk4523]

I am trying to download Knoppix for a 32 bit computer but nothing on the download site differentiates between the two versions. How do I distinguish between the two, or is there a difference?

All the applications within Knoppix-DVD are 32bit. If you have more than 3GB RAM, you can use the 64 bit boot option to have full access to whole of your RAM.
