Why do we refer to our internet speeds as "bandwidth" with units of measurement like "10 Mbps"?
As I understand it, Bandwidth is, as the name implies, the width of the frequency band, typically measured in Hertz. So if you had a signal with a spectrum from 2MHz to 10MHz, your bandwidth would be 8MHz.
Granted, bandwidth is a factor of internet speed, but it is itself not a measure of speed. So how did we get to referring to internet speed as "Bandwidth" and giving it units of measure in terms of bits per second (which is a measure of Data Rate, not bandwidth)?
Am I misunderstanding something?
