Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices.
Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware (software that is closely tied to specific hardware, and unlikely to need frequent updates) or application software in plug-in cartridges.
It is non-volatile, meaning the information stored in ROM is not lost when the computer or electronic device loses power.
ROM is used to store essential firmware, such as the computer’s BIOS (Basic Input Output System) or the firmware of other electronic devices.
