What is information readily available and accessible to the end-user?

The term for information that is readily available and accessible to the end-user is active data. Active data refers to current data that is in use and can be easily accessed and modified by the user without any additional effort. This type of data is typically stored on devices such as hard drives or cloud storage and is immediately available for operational tasks, such as processing, analysis, or presentation.

In contrast, backup data is meant for recovery purposes and is not usually accessed by end-users on a regular basis; it is stored for safekeeping against data loss. Archival data refers to data that is not actively used but is preserved for long-term retention; it is not readily accessible in a day-to-day operational context. Residual data, on the other hand, often refers to remnants of data that remain on systems or devices after deletion processes, meaning it is not in an accessible or active state.

Thus, the definition of active data aligns seamlessly with the concept of information being readily available and accessible to end-users, making it the appropriate choice.
