What does the term 'metadata' refer to?

The term 'metadata' refers to data that provides information about other data. This is essential in various contexts, such as digital files, databases, and web content, as it helps to characterize, organize, and manage data efficiently.

Metadata can include information such as the author of a document, the date created, file size, and modification history. This additional layer of information enhances understanding and usability, ensuring users can retrieve, manage, and utilize the primary data effectively. For example, in a digital image, metadata might include details about the camera settings, location, and time taken, which aids in cataloging and searching images based on specific criteria.

Understanding metadata is crucial in forensic technology as it can offer insights into file provenance and modifications, which can be critical during investigations.
