Where does the LiveCD store everything during after booting?

[kyonides]

Does it just need enought RAM to let us test the LiveCD's contents? Or does it also need to mount the swap partitions (if available)?

I'm asking this (noobish) question because I've seen that sometimes a LiveCD or ISO let us install software to test it and later it installs it on the selected partition. Is that the way it works? Or did I just get the wrong impression and ended up quite confused?

Everything done from the LiveCD is done in a RAM drive. Nothing is written to a physical HDD.

LiveCD will use swap partitions if there are swap partitions in the system (you can check this with the command "swapon -s" when running a livecd session). Of course it will try to keep things in RAM (swap usage is slow). As swap is only an extension of RAM, everything written to swap is gone when you reboot (for all effective purposes)
