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. A hub gives the signal amplification required to permit a segment to be extended a greater distance.  Passive hub simply forwards any data packets they receive over one port from one workstation to all their remaining ports.  Active hubs, also sometimes referred to as "multiport repeaters", regenerate the data bits in order to handle a strong signal.
