A storage device with rapidly rotating magnetic disks that stores digitally encoded data is called

Explanation:
A storage device that uses rapidly rotating magnetic disks to hold digitally encoded data is a hard drive. Data is stored magnetically on spinning platters, and tiny read/write heads move across the surface to access different tracks and sectors as the platters rotate. This design makes it non-volatile, meaning data stays stored even when power is off, and it’s well-suited for large, persistent storage. RAM is volatile and used for quick, temporary data access; it loses its contents when power is removed. A compact disc is optical storage read by a laser, not magnetic. A solid-state drive uses flash memory with no moving parts.
