Topology refers to the shape of a network, or the network's layout. How different nodes in a network are connected to each other and how they communicate are determined by the network's topology. Topologies are either physical or logical. Below are diagrams of the five most common network topologies.
Devices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network.
All devices are connected to a central hub. Nodes communicate across the network by passing data through the hub.
All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it.
A hybrid topology. Groups of star-configured networks are connected to a linear bus backbone.
