When the electricity power is disrupted or cut off,data and programs are lost in ?

When the electricity power is disrupted or cut off, data and programs are typically lost in volatile memory, such as RAM (Random Access Memory). This is because volatile memory requires a constant supply of electricity to retain the stored information. Once the power is cut off, the data and programs stored in volatile memory are no longer accessible and are lost. However, data and programs stored in non-volatile memory, such as hard drives or solid-state drives, are not immediately lost and can be retrieved once the power is restored.
