What does the term data read/output refer to?

The term "data read/output" specifically pertains to the process of accessing and retrieving existing data from a storage medium or database. This involves reviewing, displaying, or otherwise using the data that has already been stored, allowing users to extract useful information as needed. In computing contexts, output often refers to the results produced after data has been read, which can include displaying results on a screen or exporting data for further use.

In contrast, writing new data to storage involves saving fresh information, modifying current data refers to changing the data that is already present, and deleting outdated data pertains to removing information from storage entirely. While all these activities are related to data management, "data read/output" focus solely on retrieving and utilizing pre-existing data.
