Common Mechanisms of UML

Deployment 

➤A node is a physical element that exists at run time and represents a computational resource, generally having at least some memory and often processing capability 

• Used to model the topology of the hardware on which a system executes 
• Represents a processor or a device on which a components may be deployed 

➤Graphically, a node is represented as a cube

• Names
• Nodes and Components
• Connections
• Common Modeling Techniques

Names:

• Every node name is unique which distinguish from it from other nodes
• It has simple name and path names

Nodes and Components 

• Components participate in the execution of a system and nodes execute components 
• Components represent physical packaging where as nodes represent physical deployment of components

Connections:

• Association relationship is used among nodes 
• It shows Ethernet connection, serial line, shared bus etc 
• It also shows an indirect connection like satellite link between distant processors
