What is meant by volatile data?

Volatile data refers to information that is temporary and may be lost when the power is turned off or when the computing device is shut down. This type of data is typically stored in RAM (Random Access Memory), where it is quickly accessible for processing but is not retained once the device loses power.

Characteristics of volatile data include its dynamic nature, meaning it can change frequently, as it is often utilized for current operations by programs and applications. An example of volatile data would be the contents of a user’s open applications or the information being processed during a session.

In contrast, non-volatile data is stored on devices such as hard drives or solid-state drives, where it remains intact even when the power is turned off. Understanding the distinction between volatile and non-volatile data is essential in cybersecurity, especially when considering data recovery and preservation strategies during incidents that may lead to power loss or system shutdowns.
