Why does bandwidth matter?
A high bandwidth means that a single piece of data moves fast, which in turn means that a lot more data can move down the wire in a given amount of time. This explains why high bandwidth networks are spoken of in terms of both speed and volume. If large amounts of data can be transferred, this means that many people can use the network without overloading it and this in turn means the network will be RELIABLE. All sorts of uses become possible when people know that the network will do what they want, when they want it.
