NV or Non-volatile memory is a term used to describe any memory or storage that is saved regardless if the power to the computer is on or off. It is also called persistent storage or permanent storage. An example of non-volatile memory and storage is a computer hard drive, flash memory, and ROM. If data is stored on a hard drive, it will remain on that drive regardless if the power is interrupted, which is why it is the best place to store your data and documents. Non-volatile memory also stores your computer's time and system settings even when the power is off.
