While non-volatile memory is static and remains in the computer even when the computer is turned off. ROM and HDD are non-volatile memory. 26
Why is Ram called volatile?
Volatile memory is computer memory that retains its data only when the device is turned on. … However, the data in RAM only stays there while the computer is running. When the computer is turned off, the RAM loses its data. Volatile memory contrasts with non-volatile memory, which retains its contents in the event of a power failure.
