Question

what are the most common mass storage devices? list them in the order of their data storage density. how is non-volatile memory fundamentally different from volatile memory?

Answer 1

The most common mass storage devices in order of data storage density are solid-state drives, hard disk drives, optical disc drives, memory cards, tape drives, and USB flash drives. Non-volatile memory retains data even when power is removed, while volatile memory loses data when power is removed.

Step-by-step explanation:

The most common mass storage devices are:

1. Hard disk drives (HDDs)
2. Solid-state drives (SSDs)
3. USB flash drives
4. Optical disc drives (DVD, CD)
5. Memory cards (SD cards)
6. Tape drives

The order of their data storage density from highest to lowest is:

1. Solid-state drives (SSDs)
2. Hard disk drives (HDDs)
3. Optical disc drives (DVD, CD)
4. Memory cards (SD cards)
5. Tape drives
6. USB flash drives

Non-volatile memory is fundamentally different from volatile memory in that it retains data even when power is removed. Non-volatile memory is used for long-term storage of data that needs to be retained even after power loss. Volatile memory, on the other hand, loses its data when power is removed and is used for temporary storage.
