Answer:
Read-only memory, also known as ROM, is a storage medium used in computers and electronic devices, which allows only the reading of information and not its writing, regardless of the presence or not of an energy source.
The data stored in the ROM cannot be modified, or at least not quickly or easily. It is mainly used to contain firmware (a program that is closely linked to specific hardware, and is unlikely to require frequent updates) or other vital content for device operation, such as programs that start up the computer and perform diagnostics.
There are three types of ROM memories: PROM. EPROM, and EEPROM.
