Detailed explanation-1: -A type of memory in which the stored data is not lost when the power is turned off is called Non-Volatile memory whereas the type of memory in which the stored data is lost when the power is turned off is called Volatile memory.
Detailed explanation-2: -Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.
Detailed explanation-3: -At a high level, the biggest difference between volatile and non-volatile memory is that volatile memory stores data when a computer is on but erases it as soon as the computer is switched off, whereas non-volatile memory remains in a computer even after the system shuts off.
