Detailed explanation-1: -Volatile storage devices lose data when power is interrupted or turned off. By contrast, non-volatile devices are able to retain data regardless of the status of the power source. Common types of volatile storage include static random access memory (SRAM) and dynamic random access memory (DRAM).
Detailed explanation-2: -Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off. Unlike volatile memory, NVM does not require its memory data to be periodically refreshed. It is commonly used for secondary storage or long-term consistent storage.
Detailed explanation-3: -Non-volatile memory (NVMe) is a semiconductor technology that does not require a continuous power supply to retain the data or program code stored in a computing device.
