As used in a deployment implementation diagram, a node is a run-time physical object that represents a processing resource. Nodes are usually computing devices but can also represent human resources or mechanical processing resources.
You can define a node as either a type (with a node-type name such as PC or HostMachine) or an instance (with a name and node type, such as Joe's Machine:PC or AdminServer:HostMachine).
Node instances can contain component instances and objects, and nodes can be connected to other nodes by communication associations.

Open the element's UML Properties dialog box by double-clicking the icon that represents the element in the tree view or the shape that represents the element in a diagram.
Control which property values display on a shape in a diagram by right-clicking the shape, and then clicking Shape Display Options. In the UML Shape Display Options dialog box, select and clear options to display or hide property values.
