                       TREE TOPOLOGY
IN THIS TOPOLOGY ALL THE NODES ARE ATTACH IN HIER ARCHIEL FORM WE CAN CONNECT TWO OR MORE HUBS SWITCH WITH EACH OTHER

            HYBRID TOPOLOGY

                   HYBRIDE TOPOLOGY
WHEN WE CONNECT TWO DIFFRENT TOPOLOGY WITH EACH OTHER LIKE WHEN WE USE STAR AND BUS AND RING BOTH ARE TYPE OF HYBRIDE TOPOLOGY

STAR TOPOLOGY
