What means it must have constant power to function; its contents are lost when the computer’s electric supply fails?

Question

BlackTom AI · Accepted Answer

Consider the question stem: it asks about something that must have constant power to function and loses its contents when the computer’s electric supply fails. This description points to memory that requires power to retain data, i.e., volatile memory.
Option 1: Nonvolatile. This is incorrect because nonvolatile storage retains data even when power is removed, such as flash or hard drives. The clue in the question about losing contents without power contradicts nonvolatile behavior.
Option 2: Cache. Cache is a small, fast memory used to speed up data access and can be volatile or nonvolatile depending on design, but in most standard contexts cache is volatile and primarily serves as a temporary fast-access layer rather than the main storage described. The key feature in the prompt is the memory being unable to hold data without power, which is characteristic of volatile RAM, not specifically cache.
Option 3: Volatile. This is the correct type of memory described: volatile memory requires continuous power to maintain stored information, and any power loss results in loss of data. This matches the clue about contents being lost when the power supply fails.
Option 4: Read-only. Read-only memory (ROM) retains data without power and is not lost when power fails, which contradicts the given condition that contents are lost without power. Therefore, read-only is not a match for the description in the question.
