Which of the following storage devices is non-volatile? (2021)
Step 1: Understand what non-volatile means. Non-volatile storage keeps data even when the power is off.
Step 2: Identify the storage devices you are considering. Examples include Hard Disk Drives (HDD), Solid State Drives (SSD), USB flash drives, and RAM.
Step 3: Check which of these devices are non-volatile. HDDs, SSDs, and USB flash drives are non-volatile because they retain data without power.
Step 4: Remember that RAM (Random Access Memory) is not non-volatile because it loses data when the power is off.
Step 5: Conclude that a Hard Disk Drive (HDD) is a non-volatile storage device.
