In the STAR topology, computers are connected to a central point, called a hub. A hub is
a device that connects multiple computers and communicates messages from one
computer to the all of the computers on the network. In the star topology, if there is a
break in one of the lines, only that computer is unable to send and receive data on the
network. The star topology is the most common configuration for small networks. One of
the most common methods of transmitting data in a star network is ethernet. The most
common cable type for a star network is twisted-pair cable.
