Answer to Question 1
A deployment diagram, the last major UML tool, is used to visualize the static aspect of the physical nodes and their relationships and to specify their details for construction. This diagram is not specifically about hardware, but about how the software is configured in relation to hardware.
A deployment diagram is a structural diagram that depicts the relationship between nodes.

You can use stereotyping and other UML extension mechanisms with the deployment diagram.
