Hubs/Repeaters
Hubs/Repeaters are used to connect together two or more network segments of any media type. In larger design, signal quality starts to deteriorate as segment exceeds their maximum length.

Active hubs, also sometimes referred to as "multiport repeaters", regenerate the data bits in order to handle a strong signal.
