This is a low-level (level one) measure of the literal bandwidth of an analog communication channel. I'm pretty sure that we won't need to bring these kinds of electrical engineering concerns into our project assignment. I believe that the pupose conceptual framework we are building is to model the differing <i>usage</i> of "bandwidth" between AJAX and a standard web page, rather than to calculate capacity at the bit level.
