A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part on network documentation. Generally, a network diagram is a visual representation of your network that highlights devices, connections, paths, and data flows. Network mapping and network topology mapping are other terms for network diagramming. A network diagram can assist you in visualizing both the logical and physical features of your network.
