What does ROM stand for?

ROM stands for Read-Only Memory. This type of memory is primarily used for storing firmware, which is the software that is closely tied to specific hardware and unlikely to require frequent updates. ROM is non-volatile, meaning it retains its data even when the power is turned off.

The "read-only" aspect of ROM signifies that the data written in it cannot be easily modified or overwritten, making it ideal for software that needs to be protected from changes, such as basic input/output system (BIOS) in computers. The manipulation of data within ROM is limited, which ensures consistency and reliability for critical system functions.

In contrast to the other options, which suggest various misleading interpretations of what ROM could represent, Read-Only Memory accurately encompasses the definition and purpose of this type of memory. This clarity helps in understanding why ROM is essential in computer architecture and system design.
