Which term describes a storage device that stores digitally encoded data on rapidly rotating rigid disks with magnetic surfaces and can be portable?

• A. Hard Drive
• B. Random Access Memory
• C. Compact Disc
• D. Solid State Drive

Answer: (A)

Storing digitally encoded data on rapidly rotating rigid disks with magnetic surfaces describes magnetic storage where platters spin inside a drive and data is written magnetically. A hard drive uses magnetic material on rigid platters and a read/write head that moves to access data as the platters spin, and it can exist as internal drives or portable external drives. This differs from random access memory, which is volatile and loses data when power is removed; from a compact disc, which stores data optically rather than magnetically on rotating surfaces; and from a solid-state drive, which uses flash memory with no moving parts. So, the term that fits is a hard drive.
