Yes the if= is the input file in this case the floppy (/dev/fd0) you want to duplicate the of= or output file is the image that you want to save to hard disk and you can save it anywhere pretty much eg. of=/home/username/knoppixboot.img.

dd if=/path/to/knoppixboot.img of=/dev/fd0

is =/path/to/knoppixboot.img where the floppy drive is? How does it know where the copied file is on my HD?
That would be where the boot image is that you have saved to hard disk and want to write too a new floppy which would be the if= or input file now then you write to the of=/dev/fd0 or output file which is the floppy so you now have a duplicate.
