The term RAID stands for ______________.

• A. Redundant Array of Independent Disks
• B. Redundant Array of Inexpensive Disks
• C. Random Access Independent Disks
• D. Rapid Integrated Disk

Answer: (A)

RAID is about using multiple drives together to improve reliability and/or performance. The acronym Redundant Array of Independent Disks captures that idea: data is stored across several separate hard drives (an array), with redundancy so you can recover from a disk failure, and the drives are independent rather than being treated as a single unit. The word independent emphasizes that each disk is a separate device, which is crucial for how RAID achieves fault tolerance and speed benefits.

That’s why the term with independent disks is the best choice. The other phrasings miss the established wording and the point of RAID. Using “inexpensive” suggests cost is the defining factor, which isn’t the core concept of RAID. The options about random access or a “rapid integrated disk” don’t reflect the standard acronym or its purpose.
