Which method of data storage does an MMC card utilize?

The correct answer is that an MMC (MultiMediaCard) card utilizes flash memory technology. Flash memory is a type of non-volatile storage that retains data even when power is turned off. It is widely used in portable storage devices, including MMC cards, due to its compact size, durability, and the ability to quickly read and write data.

Flash memory allows for quick access to stored information, making it ideal for use in devices such as cameras, smartphones, and other electronics that require high-speed data storage and retrieval. Additionally, MMC cards are designed to be efficient in both power consumption and data transfer rates, further highlighting the advantages of using flash memory.

Reprogrammable memory refers to a broader class of memory types that can be rewritten, which may include flash but is not specific enough to accurately describe MMC cards. Other options like hard disk drive technology and optical storage involve completely different mechanisms—mechanical and optical methods for storing data, respectively—and are not applicable to the context of MMC cards.
