Which of the following stores data permanently?

🧠 Explanation:

Data that is stored permanently in a computer is saved on **secondary storage devices**. Unlike primary storage, which is temporary and loses data when the power is off, secondary storage retains information even when the computer is shut down. Examples include hard drives, solid-state drives, and optical discs. This permanent storage is essential for keeping files, programs, and system data safe for long-term use. It ensures that important information remains accessible whenever needed, making it a fundamental part of any computer system.
