Which of the following uses persistent memory chips to store data?

Answer:

To determine which of these options uses persistent memory chips to store data, it’s essential to understand the nature of each storage type:

  1. RAM (Random Access Memory):

    • Type of Memory: Volatile
    • Persistence: Does not use persistent memory. RAM is designed for temporary data storage and loses its contents when power is turned off.

  2. Compact Disc (CD):

    • Type of Memory: Optical Storage
    • Persistence: It uses non-volatile optical storage, not memory chips, for data. Data remains intact without power, but it doesn’t utilize memory chips in the way persistent memory does.

  3. Hard Disk (HDD):

    • Type of Memory: Magnetic Storage
    • Persistence: Uses non-volatile memory, where data persists after power off, but it relies on magnetic platters and not memory chips.

  4. Flash Drive:

    • Type of Memory: Flash Memory
    • Persistence: Uses non-volatile memory chips (specifically NAND type) for data storage. Flash drives retain data without power.

Based on these explanations, Flash Drive is the correct answer. It uses persistent memory chips (flash memory) to store data, allowing the data to remain even when the device is not powered.
