at different scales diagrams may represent various levels of network granularity. @ lan level, individual nodes may represent individual physical devices, such hubs or file servers, while @ wan level, individual nodes may represent entire cities. in addition, when scope of diagram crosses common lan/man/wan boundaries, representative hypothetical devices may depicted instead of showing existing nodes. example, if network appliance intended connected through internet many end-user mobile devices, single such device may depicted purposes of showing general relationship between appliance , such device.
