Networking Guide : Network Topologies
In star topology, all nodes are connected to a central point
which is called a hub.
A sending node transmits its message (signal) to the hub. The hub then
retransmits
the signals to all other nodes. Each receiving node checks the
signal's
destination address, if it matches the node's address it processes the
signals.
A star network is easier to monitor because it has a central
point. Adding and removing a node is as simple as plugging a cable
to a wall jack or a hub. Failure in one node doesn't affect the
other nodes. However, if the hub fails the network will stop
working. Ethernet
10BaseT, 100BaseT, and
1000BaseT networks are
examples of LAN technology that uses star topology.

Each node is connected to a hub.
Cluster tree topology is a star topology that has branches. A
cluster tree network derives the attributes of a star network.

Two hubs provide connection between two star networks.
