Streaming media refers to multimedia for playback using an offline or online media player that is delivered through a network. Media is transferred in a "stream" of packets from a server to a client and is rendered in real-time; this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content. Streaming is presently most prevalent in video-on-demand, streaming television, and music streaming services over the Internet.
