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.
