BD-ROM stands for which storage medium?

• A. Blu-ray Disc Read-only Memory
• B. Blu-ray Disc Read-Optional Memory
• C. Binary Disc Read-Only Memory
• D. Blu-ray Disk Recordable Memory

Answer: (A)

BD-ROM stands for Blu-ray Disc Read-Only Memory. The Read-Only Memory portion means the data on the disc is pre-pressed at the factory and cannot be altered by the user in normal operation. This is typical for discs that contain movies, software, or other content distributed in a fixed form. The other options mix up the terminology: it’s not Read-Optional Memory, not Binary, and not Disk Recordable Memory—the writable formats are BD-R or BD-RE, while BD-ROM is the read-only variant.
