this might sound a really stoopid question but i have got myself totally confused, does anyone know what happens to the information you are working on after you save it? i no ROM memory is lost after computer is switched of so where does it go?? HELP!!
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.
