What happens to data in volatile memory when the device is powered off?

• A. Data is transferred to non-volatile storage
• B. Data is retained
• C. Data is erased
• D. Data is encrypted

Answer: (C)

Volatile memory, such as RAM (Random Access Memory), is designed to store data temporarily while a device is powered on. When the device is powered off, all the data stored in volatile memory is erased. This is a fundamental characteristic of volatile memory; it requires a constant power supply to maintain the stored information. Once power is removed, the electrical charges that represent data dissipate, leading to the complete loss of that data. This distinguishes volatile memory from non-volatile memory, like flash storage, where data persists even when the power is turned off. Understanding this concept is crucial for effectively managing data retention and system performance in various computing environments.
