What is a key characteristic of non-volatile storage?

• A. It loses data when powered off
• B. It retains data without power
• C. It is only suitable for temporary files
• D. It requires constant internet connection

Answer: (B)

Non-volatile storage is characterized by its ability to retain data even when the power is turned off. This characteristic is essential for preserving important information over time without the need for a continuous power supply. Devices such as hard drives, solid-state drives, USB flash drives, and ROM (Read-Only Memory) are examples of non-volatile storage, as they can save files and system information indefinitely under the right conditions.

In contrast, volatile storage, like RAM (Random Access Memory), requires power to maintain the information stored within it and will lose all content once powered down. Other options that suggest limited use cases or dependency on power and internet connection do not accurately describe the fundamental nature of non-volatile storage, which is designed for long-term data retention.
