The bandwidth of a network is primarily measured in terms of bitrate, which refers to the amount of data transmitted over the network in a given amount of time, typically expressed in bits per second (bps). The higher the bitrate, the more data can be transferred simultaneously, resulting in higher bandwidth.
To further clarify, bandwidth can also relate to the frequency of the signals used in the network. In communication systems, a higher frequency allows for the transmission of more data within the same channel, thus achieving higher bandwidth. This is particularly relevant in technologies like radio communications and fiber optics, where the capacity of the medium to carry signals is closely tied to the frequency of the waves used.
In summary, while bitrate is a direct measure of how much data can be transmitted, frequency plays a significant role in determining the overall capacity of a network's bandwidth by enabling the transmission of more data within the same timeframe when higher frequencies are utilized.
