Meaning – Bandwidth is defined as the difference between the highest and lowest frequencies, among a range of frequencies. It is expressed in the units ‘Hertz’.
In the context of networks, bandwidth refers to the amount of data that is transmitted over an internet connection, in a given amount of time. The common misconception here is that the bandwidth is assumed to be the speed of the internet connection. However, it is actually the volume of data that can sent over the internet connection in a given amount of time.
The Bandwidth in networks is calculated in Megabits per Second.
