Non-volatile memory is a type of computer storage that retains data even when the power is turned off. Unlike volatile memory, such as RAM, which loses its information when the device is powered down, non-volatile memory ensures that important data remains intact. Common examples include flash memory, hard drives, and solid-state drives (SSDs). This type of memory is essential for storing files, applications, and the operating system on devices like smartphones, laptops, and tablets. Non-volatile memory allows users to access their data quickly and reliably, making it a crucial component in modern computing technology.
