The Network Topology Types Template describes the physical arrangement of a network's nodes and other components. Network topology diagrams are used to illustrate the structure, operation, and behavior of a communication network. Symbols and icons are used to represent the various nodes, devices, routers, switches, etc., in a network, and connections are drawn between them to show the order in which they are used. There are a few different approaches you can take when drawing topology diagrams. They can be drawn manually or with the help of a computer program.
