These are the only relevant links I've been able to find. You have to sort through the second website quite a lot but it has the most relevant info...I think.

RAM is volatile, which means its content 'evaporate' when the machine is powered off.

ROM is permanent storage which is programmed at manufacture and cannot be overwritten or deleted. It retains its content when the system is powered off. The bootstrap loader is an example of ROM.

Hope this helps!

Ram is lost, Rom isnt. The ram is just wiped automatically when it is turned off, because it relies on the power supply to keep it running.
The rom is non-deletable, and generally non re-writable without expensive hardware, or specialist rom chips.
