• A network hub or repeater hub is a device


• to connecting multiple twisted pair or fiber optic ethernet devices together and making them as a single network segment


• computer and other devices are connected to the hub individual network cable


• Hubs do not manage any of the traffic that comes through them


• All the packets entering in any port in the hub is broadcast out on all other ports


• When we use the hosts to detect collisions,it will limit the number of hubs and total size of the network built using hubs
