Non-volatile storage refers to a type of computer memory that retains data even when the power is turned off. This makes it essential for storing important information, such as files and applications, that need to be preserved over time. Common examples of non-volatile storage include hard drives, solid-state drives (SSDs), and flash memory. Unlike volatile memory, like RAM, which loses its data when power is lost, non-volatile storage ensures that data remains intact. This characteristic is crucial for devices like smartphones, tablets, and computers, where users rely on saved data being available whenever needed.
