Bandwidth has two different aspects to it: a computing side and a signal processing side.

On the computing side, bandwidth is about the velocity at which data is transferred between sources. It is usually seen as ‘speed of an internet connection’.

Under computing bandwidth, network bandwidth capacity refers to information rate at each communications happen. Network bandwidth consumption refers to the amount of bits that have been used during data transfer.

In terms of signal processing, bandwidth refers to the difference between the upper and lower frequencies in a continuous set of frequencies.

Measurements represented in hertz, instead of bits as it happens with computing bandwidth.

Bandwidth is the pillar to many telephony communications that still take place today, including for example radio communications.

In the radio scenario, bandwidth becomes the frequency range occupied by a modulated carrier signal.
