Detailed explanation-1: -ROM is a non-volatile memory containing data that we cannot change. In this case, information is not lost when the power supply is turned off. ROM information is determined by the computer manufacturer and is permanently stored at the time of manufacture so that the user cannot overwrite it.
Detailed explanation-2: -ROM that is read only memory is non volatile because all the data in it doesn’t get erased after shutting down the computer and restarting it. Flash memory-Flash memory is a type of erasable read-only memory (EEPROM) that clears and rewrites data in chunks for fast, energy-efficient access and rewriting.
Detailed explanation-3: -A computer’s volatile memory is sometimes referred to as primary storage, as opposed to secondary storage, which is typically made up of nonvolatile storage devices.
Detailed explanation-4: -ROM is non-volatile memory, which means the information is permanently stored on the chip. The memory does not depend on an electric current to save data, instead, data is written to individual cells using binary code.
