Naturally, computers have become widespread and are used for a wide variety of purposes beyond solving computationally difficult problems. Gilder's Law", a conjecture like Moore's Law, predicts that total bandwidth — a measure of the carrying capacity of a communication system — will grow at least three times faster than computing power (Gilder, 2000). Thus, if computing power doubles every 18 months, as projected by Moore's Law, then Gilder's Law predicts that bandwidth will double every six months.
