What instructions remain on a storage medium until they are needed?

Instructions that remain on a storage medium until they are needed are typically referred to as "stored programs" or "software." These programs are saved in non-volatile memory, such as hard drives or solid-state drives, and they include the code and data necessary for a system to perform specific tasks. When required, the processor retrieves these instructions from storage, loads them into memory, and executes them. This concept underpins the operation of modern computers, allowing for efficient and flexible task management.
