An Introduction to Bandwidth
Bandwidth is a term that gets tossed around very loosely these days. One often hears about how certain applications, such as videoconferencing, require very large bandwidths for transmission. Also widely discussed is how fiber optic and coaxial cables provide this high bandwidth to make such applications possible. So in a qualitative sense, bandwidth is known to be related to the amount of information that may be squeezed through a transmission channel.However, it is not widely understood in a quantitative sense. If someone were to ask you "How many telephone conversations can be carried over a T1 line?", would you be able to answer? Many people wouldn't. But with the rise in importance of information technology in people's everyday lives, this question becomes more relevant. As internet-mania spreads, people are going to soon be facing the choice between, say, an ISDN modem or a cable modem for their on-line connection. The differences between them will basically amount to bandwidth and cost, so understanding of the concept of bandwidth will make the decision much simpler.
