Data Persistence

Data persistence refers to the ability of information to remain stored and accessible even after a device is turned off or restarted. It's like writing a note on paper: once saved, it stays until deliberately erased. In digital systems, this typically involves saving data to storage devices like hard drives or cloud servers. This ensures that important data, such as documents, photos, or application settings, is reliably available over time, enabling continuous access and use across sessions without loss.
