Which type of data is described as volatile?

Volatile data refers to information that is stored in a temporary environment and is lost when the power is turned off. This type of data is typically found in computer memory forms such as RAM (Random Access Memory), where the data is actively being used by applications and processes while the computer is powered on. Once the power is interrupted, all data held in this form of memory is erased, making it transient in nature.

In contrast, non-volatile data, such as information stored on hard drives, SSDs, and other permanent storage solutions, remains intact even when the device is powered down. This distinction is crucial in understanding how different types of storage affect data retention and usage within computer systems.
