If the load InputImpedance (resistance) is equal to the drivers OutputImpedance, the power at the load is at a maximum. If there is a TransmissionLine connecting the driver to the load, it must also have a CharacteristicImpedance close to the OutputImpedance, so as to instantaneously load the driver to the right load, to prevent ringing in the circuit. Imagine you take a TransmissionLine and make an incision, both sides of the TransmissionLine will be the same CharacteristicImpedance as the original line. This can be modeled as a amplifier with unity gain (0dB) and an InputImpedance and OutputImpedance equal to the CharacteristicImpedance of each respective side, ensuring maximum power is transferred.

Hey. This is getting fairly far from

at least remove all the wikiwords and

define these terms on the same

+[IMHO], It's kinda on topic as it interests people that are trying to maintain Unix machines, mostly in understanding why you need Bus Termination ([SCSI] anyone? [ThinNet]?), and other related things (Why are there 3.3v [PCI] cards?). Lets see what JamesSpooner adds, and perhaps look at condensing it/removing irrelevant material in a few months if it's not used. -- PerryLorier
