Frequency: The amount of data that can be transmitted on a channel depends on the wave frequency – the cycles of waves per second. Frequency is expressed in hertz. One hertz is equal to one cycle of the medium
Bandwidth: is the different between the highest and lowest frequency – that is, the range of frequencies. The rate of speed of data through the channel is expressed in bits per second (bps), kilobits per second (Kbps), or megabits per second (Mbps)
Higher Frequency, Wider Bandwidth, More Data
