What does the term "non-volatile memory" refer to?

Non-volatile memory refers to a type of computer memory that retains stored information even when not powered. This characteristic is essential for applications where data must be preserved across power cycles, such as in flash drives, ROM (Read-Only Memory), and SSDs (Solid State Drives). The ability to maintain data without continuous power allows for the persistent storage of important information, settings, or user data, making non-volatile memory critical for devices that need to access data quickly after being turned off or restarted.

In contrast, the other options describe types of memory with different properties. Memory that requires continuous power will lose its data when power is disconnected, which is characteristic of volatile memory types like RAM. Temporary data storage is typically associated with volatile memory used for active processes and calculations, while high-speed temporary storage is also indicative of volatile memory systems that enhance performance during computation but do not hold data long-term.
