The term "life span" in the context of data refers specifically to the validity period of information. This concept encompasses the duration during which the data remains accurate, relevant, and trustworthy before it becomes obsolete or unusable due to changes in context, technology, or other factors.

Understanding the life span of data is crucial for ensuring that decisions based on that data are made while the information is still meaningful. As data is subject to decay over time, recognizing its life span helps organizations manage their data effectively, allowing for timely updates, validation, and disposal of information that is no longer beneficial or accurate.

In contrast to the other concepts presented, the validity period highlights the importance of keeping data relevant, while the time taken to document data, capacity of storage media, and duration of data retrieval address different aspects of data management and handling rather than its temporal relevance or suitability.
