Frequency in networking

Bandwidth, also referred to as Frequency Response, is an indication of a displacement sensor’s ability to respond to changes in the measured displacement . It is measured at the -3dB point and gives indication of: How the output changes relative to the frequency of a vibrating target.

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies . It is typically measured in hertz, and depending on context, may specifically refer to passband bandwidth or baseband bandwidth.

A critical parameter of any communications system is bandwidth, which characterizes its information-carrying capacity. Access to the Internet, for example, is much faster via a broadband than a dial-up connection. This is mainly because a broadband connection uses higher frequencies to convey digital data .
