What term describes the risk that electronic data may become unreadable when moved away from its original environment?

• A. Data integrity
• B. Environment-dependence and obsolescence
• C. Data sovereignty
• D. Platform independence

Answer: (B)

The main concept is environment dependence and obsolescence: the risk that electronic data becomes unreadable when moved away from the original hardware, software, or platform it relies on. Digital records often depend on specific formats, viewers, or system configurations. When those environments change—formats become outdated, software is retired, or devices are replaced—the data can no longer be accessed in its original form unless it’s migrated or preserved with compatible tools. For instance, a patient report saved in a proprietary, legacy format may be unreadable after migration if the new system doesn’t support that format, unless you convert it or keep an accessible way to read old files. This differs from data integrity, which is about accuracy and completeness of data, and from data sovereignty, which concerns legal control and jurisdiction. Platform independence would actually reduce this risk, so the term that best describes the unreadability risk is environment dependence and obsolescence. To mitigate, use open formats, maintain documentation, plan regular format migrations, and preserve metadata and access to old systems or emulation tools.
