Which data type is lost when a device is powered off?

• A. Non-volatile data
• B. Archived data
• C. Volatile data
• D. Persistent data

Answer: (C)

Volatile data refers to information that is stored temporarily and is lost when the device is powered off. This type of data is typically found in the device's RAM (Random Access Memory), where it is held only as long as the power supply is active. Examples of volatile data include the contents of currently running applications, unsaved work, and the system's current state. In contrast, non-volatile data is retained even after a device is powered down; it includes data stored on hard drives and SSDs, such as files and user settings. Archived data also implies a form of long-term storage, and persistent data is designed to remain available unless intentionally deleted. Understanding these distinctions is crucial for digital forensics, as volatile data can provide valuable insights into a device's active processes and usage right before it was powered off.
