What is the difference between volatile and non-volatile data?

Volatile data refers to information that is stored in temporary memory and is lost when the power is turned off or the system is restarted. This includes data in RAM (Random Access Memory), cache memory, and registers. Non-volatile data, on the other hand, is information that is stored in permanent memory and remains intact even when the power is turned off or the system is restarted. This includes data stored on hard drives, solid-state drives, optical media, and other storage devices.
