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.
Network topology is the layout of the connections (links, nodes, etc.) of a computer network. There are two main types of topology. Network topologies may be physical or logical. Physical topology means the physical design of a network including the devices, locations and cables. Logical topology is about how data is actually moved around in a network, not its physical design.
