Which of the following stores data permanently in a computer?

🧠 Explanation:

The component that stores data permanently in a computer is known as **secondary storage** or **non-volatile memory**. Unlike primary storage, which loses data when the power is turned off, this storage retains information even when the computer is shut down. Common examples include hard drives, solid-state drives, and optical discs. Permanent data storage is essential for saving files, programs, and system information for long-term use.
