What type of data does both sound and video represent in multimedia?

Sound and video are both forms of data that are characterized as stream data because they require continuous transmission to maintain playback. This means that they are inherently temporal, capturing changes over time, which is essential for conveying information in the form of audio and moving images.

Stream data allows for real-time playback and interaction, as the data is processed in sequences of small packets. In multimedia applications, this is crucial for providing a seamless experience, where the audio must sync with the visuals. Unlike static data, which represents fixed content like images and text, stream data is dynamic and must be processed on-the-fly. Additionally, it contrasts with frame data, which typically refers to individual snapshots in video rather than the continuous flow. Hence, the correct classification of both sound and video is stream data, reflecting their nature as constantly changing media that relies on continuous signal processing.
