Final answer:
ROM stands for Read Only Memory, which is non-volatile storage used for firmware or software in electronic devices and cannot be easily written to after initial programming.
Step-by-step explanation:
The term ROM stands for C. Read Only Memory. ROM is a type of non-volatile storage that is primarily used in computers and other electronic devices to store firmware or software that is rarely changed or updated, such as the BIOS in a personal computer.
Unlike RAM (Random Access Memory), which is used for temporary storage and can be written to and read from freely, the data on ROM can only be read and not easily written to or modified after initial programming. This is why it's called "read-only" memory.
