What is Streaming?

At times you may find you are having difficulty getting your computer online at school. All the data has to run through our pipe. That pipe is only so big. Certain things take up more than their share of the pipe. For example, if one person is "streaming" it can bring the entire building to a snail's pace. If two people are streaming, well, you get the idea!

Audio Streaming is things like "Pandora Radio", "NPR Radio", or any online or iTunes radio for that matter.  Video Streaming is similar, but involves the video portion as well as the audio. An example would be viewing a video clip from a news site, such as CNN or Yahoo News. Have you notice how sometimes it stops and re-starts? Or, how it may be jittery?  It’s having trouble getting all the resources it needs to send it to you smoothly.

On some sites you can save the video onto your hard drive at home, and then play it back at school. That way the video is not coming off the internet and through our pipe and slowing down the server. You are streaming it at home, not at school.

So, several classrooms streaming video or audio at the same time will slow down the network.
