The term ROM stands for Read Only Memory. It is a type of non-volatile memory used in computers and other devices that retains its data even when the power is turned off. This characteristic makes it distinct from volatile memory like RAM (Random Access Memory), which loses its contents when power is lost.

Read Only Memory is typically used to store firmware or software that is closely tied to specific hardware. This includes system firmware that boots the computer, device drivers, and other essential programs that enable basic functions. The data in ROM is often programmed during manufacturing, meaning that it is not meant to be modified frequently or at all by the user.

The other options present alternative terms related to memory but do not accurately describe ROM. For instance, Random Access Memory (RAM) is used for temporary storage of data that the CPU needs to access quickly, while the other choices provided do not correspond to established computer memory terminology.
