The type of short-term storage that stores firmware and is very hard to make changes to is called **Read-Only Memory (ROM)**. ROM is used to store firmware, which is the low-level software that provides the necessary instructions for how the device communicates with the other hardware components. Because ROM is designed to be read and not written to frequently, it is inherently difficult to modify, making it a stable option for storing critical system software.
