What is another term for a disc image?

A disc image is commonly referred to as an ISO image because it is a file that contains a complete copy of a disc's data, including the file system and structure. The term "ISO" comes from the ISO 9660 file system standard, which is used for CD-ROM media. An ISO image allows users to replicate the entire contents of a disc, making it easier to share or store data without needing the physical disc.

This term is widely used in the context of burning discs, emulating drives, and creating backups of software and operating systems. The usage of ISO images also simplifies the distribution of software, as users can download a single file that contains everything needed to recreate the original disc.

Other terms such as "File Archive," "Virtual Disk," and "Backup Copy" may refer to similar concepts in data management or storage, but they do not specifically represent the comprehensive nature and structure of what an ISO image encapsulates. An ISO image is distinct in its ability to reproduce the exact format and usability of the original disc, which is why it is the most appropriate term in this context.
