Which unit holds Data Permanently?

The secondary stage unit holds data permanently. Information is stored permanently in the secondary storage unit, which is often referred to as auxiliary memory. Its storage capacity is bigger than its primary memory and allows for long-term storage. It moves more slowly than the major one. Secondary memory is non-volatile because it is less expensive and can maintain the data or information stored in it even when a computer device is turned off or reset. The CPU cannot directly access the data stored in this memory.

Example: The magnetic disc like DVDs, CD-ROMs, etc.
