Tree Topology: This is a hybrid topology that combines characteristics of linear bus and star topologies. In a tree network, groups of star-configured networks are connected to a linear bus backbone cable.
1 Money. 2  A linear bus network may be the least expensive way to install a network; you do not have to purchase concentrators. 3  Length of cable needed. 4  The linear bus network uses shorter lengths of cable. 5  Future growth. 6  With a star topology, expanding a network is easily done by adding another concentrator.
