The standard 10Base-T termination (end point, 0 plug, connector) is the registered jack-45 connector (RJ-45). It reduces noise, reflection, and mechanical stability problems, and resembles a phone plug, except that it has eight conductors instead of four. It is considered a passive networking component because it only serves as a conducting path between the four pairs of Category 5 twisted cable and the prongs of the RJ-45 jack. It is considered a Layer 1 component, rather than a device, because it serves only as a conducting path for bits.
