What happen to the saved data in the ROM?

Data saved in Read-Only Memory (ROM) remains intact even when the power is turned off, as ROM is non-volatile memory. This makes it ideal for storing firmware and system-level software that must be preserved across reboots. However, unlike RAM, the data in ROM cannot be easily modified or erased during normal operation, which is why it is primarily used for permanent storage of essential instructions. Any changes to the data typically require special processes, such as reprogramming the ROM.
