Signals sent from the source to the destination, transmission time and the transmission distance have a relationship? What is matter?
I see video teacher's explanation, say 5 m of data, with the rate of 5 MBPS, sent to the destination only need to 1 second, so what is the transmission distance in this concept?

CodePudding user response:

5 MBPS=5 MB/s=0.625 MB/s
You listen to his nonsense,
5 MBPS data transmission between refers to from A to B, through the data rate; Rate and distance, indeed is also affected by the distance, but not to concern about the additional parameters (but the network transmission speed will only consider link quality, rather than physical distance); At the same time, 5 MBPS is as a result, the factors (including distance) is due, so should not pour fruit for the cause, take 5 MBPS and, in turn, to calculate the distance,

The individual feels the understanding of these concepts is as follows:
"A send A computer data, through 100 m Ethernet cable to the computer B" for example
1. 5 MBPS said the rate on the computer to send the data to A string, which can put 5 m per second of data on the Internet,
2. The data transmission time is from Internet computer this side to the Internet computer B this end time, 100 meters is the transmission distance, relationship is 100 m=* signal transmission time on the Internet at A rate of,

100 m=* signal transmission time on the Internet at a rate of, take all the unit, and have a look at your formula,

Description may not clear, the rate of signal in the cable, refers to the signal transmission rate
