Which of the following is NOT a characteristic of secondary storage?

The characteristic that is NOT true for secondary storage is that it is volatile. Volatility refers to whether data is retained when power is turned off. Secondary storage devices, such as hard drives and solid-state drives, retain information even when there is no power, making them non-volatile. This means that the data stored on these devices remains intact regardless of whether the device is powered on or off.

In contrast, primary storage, like RAM (Random Access Memory), is volatile, meaning it loses all stored information when the power is turned off. This distinction between secondary storage being non-volatile and primary storage being volatile helps clarify the role of different types of memory in a computer system.

The other characteristics mentioned, such as secondary storage being slower than primary storage and being used to store data permanently, are accurate, as secondary storage is designed for long-term data retention and typically operates at slower speeds compared to the rapid access speeds associated with primary memory.
