What does it imply when a teacher shows a video that starts playing immediately after clicking the link?

When a teacher shows a video that starts playing immediately after clicking the link, it implies that the video is streaming. Streaming refers to the process of delivering video or audio content over the internet in real-time, allowing the viewer to begin watching without having to wait for the entire file to download. This is facilitated through a continuous flow of data that plays the content as it is being sent, enabling immediate playback.

In contrast, downloading would require the file to be fully saved to the device before playback, which is not the case here. Broadcasting refers to transmitting a signal over a wide area, which typically relates to live events or channels rather than on-demand video content. Buffering occurs when the video playback is temporarily halted to gather enough data to play smoothly, indicating that the video is not yet fully loaded. Hence, the immediate playback after clicking the link clearly indicates that the video is being streamed.
