Bandwidth and Streaming
If bandwidth is low, traffic becomes congested If bandwidth increases, information travel happens
without a hassle Bandwidth is important – large audio and video
data over the internet requires bandwidth Streaming makes it possible to watch live or on
demand video No downloading on to the computer
Streaming
Servers hold video data When a video is to be watched, the right command
is clicked like”play” or “watch” This sends a message to the server to watch the
particular video Server responds by sending the necessary data Necessary streaming media protocols are used to
make sure data is in good condition A plug in or player on the computer decodes and
plays the video signal
