Explain the primary difference between random access memory (RAM) and read-only memory (ROM).

RAM chips are volatile storage devices, meaning they lose their contents if the current is turned off or disrupted (as happens in a power surge, brownout, or electrical noise generated by lightning or nearby machines). ROM is nonvolatile meaning that its contents are not lost if the power is turned off or interrupted.
