A node[1] in the Unified Modeling Language (UML) is a computational resource upon which UML artifacts may be deployed for execution.
Nodes can be interconnected through communication paths to define network structures.
A communication path is an "association between two DeploymentTargets, through which they are able to exchange signals and messages".
[2] When modeling devices, it is possible to model them in several different ways: Use tagged values to specify characteristics of devices / execution environments, for instance "Memory=2GB", "Disk Space=32GB", "Version=2.5.1".
