Here's a word you may not know...
streaming
Streaming usually refers to audio or video content played over the Internet. To avoid long delays in waiting for a large audio or video file to download, streaming actually downloads only the first part of the audio or video file using a process called buffering and then immediately starts playing it. While you are listening to a portion of the audio or watching a portion of the video, the remainder of the audio or video file continues to download. So in a sense, when you are streaming you are listening or watching at the same time the file is downloading.
