"Read-only memory"

Read-only memory it is mainly used to distribute firmware is a class of storage media used in computers and other electronic devices. Because data stored in ROM cannot be modified.In its strictest sense, ROM refers only to mask ROM However, more modern types such as EPROM and flash EEPROM can be erased and re-programmed multiple times; they are still described as "read-only memory".
