Hub
An unintelligent network device that sends one signal to all of the stations connected to it.
All computers/devices are competing for attention because it takes the data that comes into a port and sends it out all the other ports in the hub.
Traditionally, hubs are used for star topology networks, but they are often used with other configurations to make it easy to add and remove computers without bringing down the network.
