Secondary storage refers to any non-volatile device or media that stores data for long-term use on a computer. Unlike primary storage, like RAM, which is used for temporary data access while a computer is running, secondary storage retains data even when the computer is turned off. Examples include hard drives, solid-state drives, USB flash drives, and CDs or DVDs. This storage is essential for saving files, applications, and the operating system, ensuring you can access your data whenever you need it. It usually offers more space than primary storage and is a key topic in GCSE Computer Science.
