What happens to data stored in RAM when the power is lost?

Data stored in RAM (Random Access Memory) is volatile, which means it requires a constant power supply to maintain the information stored in it. When the power is lost or interrupted, all data in RAM is not saved anywhere and is wiped completely. This characteristic of RAM is essential for its role in computing, allowing quick access and manipulation of data while the system is running. Unlike storage devices such as hard drives or SSDs, which permanently retain data even when powered off, RAM's design prioritizes speed and efficiency for active processes. This is why after a power loss, any unsaved work or data that was only held in RAM is permanently lost.
