Criteria
3: Explains how metadata and data mining can be used to prevent technical difficulties during the broadcast. 2: Outlines how metadata AND/OR data mining can be used. 1: Identifies a feature of metadata or data mining.
Sample answer
Metadata describes the content, structure and meaning of raw data, enabling more effective, accurate and efficient data mining. Data mining identifies user preferences and viewing patterns from large datasets, helping streaming services personalise recommendations and identify times of predicted high demand. Streaming service management uses this along with real-time user data to balance server loads and deliver smooth playback experiences.
