P    Bandwidth. The term bandwidth sometimes defines the net bit rate 'peak bit rate', 'information rate,' or physical layer 'useful bit rate', channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system. Bandwidth is also described as the carrying capacity of a channel or the data transfer speed of that channel. In communications engineering, bandwidth is the measure of the width of a range of frequencies, measured in Hertz. Bandwidth We can define Bandwidth as the portion of the electromagnetic spectrum occupied by a signal. Though there is an infinite spectrum of frequencies available, it is not possible to use every frequency for communication purposes, except only those under a few hundred GHz. Communication Bandwidth: Bandwidth as a Measure of Data Transfer Given the actual definition of bandwidth—i.e., the width of a band of frequencies—why is this term used to describe concepts like data transfer rates?
