Volatile memory is memory that loses its contents when power is removed. It relies on continual power to maintain the electrical states representing data, so once the power is cut, the information disappears. This is typical of RAM used for active work in a computer. In contrast, nonvolatile memory retains data without power, such as flash or ROM, which is why stored data remains after you shut down. The other terms aren’t standard labels for this property: stable isn’t a technical descriptor for retention on power loss, and persistent is more about data surviving across sessions but doesn’t specify the power-off behavior. So, the term describing memory that loses contents when power is removed is volatile memory.
