What does metadata provide in digital files?

Metadata serves as a crucial layer of information that describes and gives context to other data. In digital files, it effectively encapsulates various attributes that help users and systems identify, manage, and organize the data more efficiently. This can include details such as the creation date, author, file format, and even keywords related to the content, all of which enhance the understanding and usability of the file without altering its actual content.

While other options describe aspects of files, they don't encapsulate the broader role of metadata. For instance, information about the file's size pertains to a specific characteristic of the file rather than providing context about the data itself. Similarly, a description of file content focuses on what the file contains but doesn't encompass the full range of metadata provided. Lastly, while passwords may be essential for securing files, they do not pertain to the broader definition of metadata, which is centered on the description and context of the data rather than access controls. Thus, the notion of metadata as "data providing information about other data" is the most accurate representation of its function.
