Hubs are not common these days and for good reason. Instead of intelligently sending traffic where it needs to go using a MAC address and/or IP address a Hub broadcasts all traffic on all ports. For example if a 48 port Hub receives a packet, it is going to broadcast that packet out on the remaining 47 ports. Generally speaking if you come across a Hub today it should be replaced with a switch instead.
