Speed and Bandwidth ```Name: M. M. G. Status: Other Age: Old Location: N/A Country: N/A Date: January 2004 ``` Question: How does speed increase with the increase in bandwidth in the Internet? Replies: Suppose all the cars on a one-lane street were 50 feet long, and each carried only one person. If they travelled bumper-to-bumper at 50 feet per second, the street could carry one person per second past any given point. If cars were shortened to be only five feet long, the street could then carry 10 people per second past any given point. Shortening the cars is analogous to increasing the bandwidth. The individual bits of information do not travel any faster when bandwidth is increased from, say, 10 million bits per second to 100 million bits per second -- they always travel at something like 1/3 the speed of light, in a wire -- but more of them can be packed into the same lengt of wire. Tim Mooney Speed IS bandwidth. They are in essence the same thing to the end user! A provider would have a slightly different definition. Obviously the bigger the "pipe" the more bandwidth, with fiber-optics at the moment being the biggest pipe. Lou Harnisch Click here to return to the Computer Science Archives
