I've been hearing the term a lot lately: bandwith. It just vibrated in my head with little real significance until recently. When talking about computers, I always knew bandwith refers to the rate of data transfer. In that sense, bandwidth is important for most everybody in modern society, seeing as its hard to be patient when a youtube video stops mid-stream. Beyond computers, bandwidth is also the heart and soul of radio communication, because it designates each radio "band," in order to keep people from overlapping their frequencies. The radio bandwidth also corresponds to an amount of data that a signal can carry (the bandwidth of a human voice is 3kHz 'wide', for example). This kind of knowledge is a perk of taking amateur radio, I guess, which I find fascinating.
