What is phase 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.

Frequency is a measure of the number of cycles that are done per unit of time and is generally measured in hertz (cycles per second). Data cabling is normally rated in kilohertz (kHz) or megahertz (MHz).12 Eyl 2017

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 .
