I will make it bold, normal, bold, normal so you don't get confused.

Okay when I did the DF command it said:
Filesystem 1k-blocks Used Available Use% Mouted on
/dev/root 3471 1108 2363 32% /
/dev/hdc 716308 716308 0 100% /cdrom
/dex/cloop 1943588 1943588 0 100% /KNOPPIX
/ramdisk 149992 2012 147980 2% /ramdisk

How do I turn off stuff, Is this okay?

Okay here is what the swapoff command said
usage: swapoff [-hV]
swapoff -a [-v]
swapoff [-v] special ...

Is this okay, what does it mean?
