What does ISO9660 stand for?

ISO descriptor for USB data storage format
ISO descriptor for DVD data storage format
ISO descriptor for CD data storage format
ISO descriptor for Blu-Ray data storage format

The correct answer is: ISO descriptor for CD data storage format

ISO9660 stands for the International Organization for Standardization's specification that defines a standard file system for CD-ROM media. It was developed to ensure compatibility across multiple platforms, allowing different operating systems to read the content on CD-ROMs. This standard supports hierarchical file organization and provides a means for storing file names and directories, making it essential for data storage on CDs. The other options relate to data storage formats that are specific to USB drives, DVDs, and Blu-Ray discs, which are governed by different standards and specifications not denoted by ISO9660. Therefore, the choice indicating that it is an ISO descriptor for CD data storage format is correct.
