A hub is a common connection point for devices in a network. When a hub receives a packet of data (an Ethernet frame ) at one of its ports from a network device, it transmits (repeats) the packet to all of its ports to all of the other network devices. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. Compared to a standard switch, the hub is slower as it can send or receive information just not at the same time, but typically costs more than a hub.
