Which term describes data that does not change?

The term that best describes data that does not change is "static." Static data is characterized by its stability and permanence; it remains constant over time. This type of data is often used in situations where the information does not require frequent updates or modifications, such as the values stored in a historical database or fixed configuration settings.

In contrast, dynamic data is designed to change and is often updated in real-time or on a regular schedule, reflecting ongoing transactions or interactions within a system. Mutable data refers to any data that can be changed or modified, which is inherently the opposite of static data. Variable data suggests that the information can take on different values, indicating variability rather than consistency. Therefore, static fits best as it emphasizes the notion of unchanging data.
