Deployment Diagram

A deployment diagram models the physical deployment of artifacts on components in a system.

Diagram Model

Name	Graphical Representation	Description
Device		A device is a deployment target which represents a computational resource, e.g. hardware component with processing capabilities upon which artifacts or software components may be deployed for execution. A device can be connected to other devices and communicate with other devices. Hierarchical devices can be modeled using composition or by defining an internal structure. Examples are: µCs, µPs, cores, switches, crystals, etc.
Physical Component		A physical component represents physical parts, which are used by the device to provide the processing capabilities, e.g. RAM, ROM, flash, cache, etc. Physical components do not provide processing capabilities.
Component / Module		Replaceable, modular piece of a system, see also Component Diagram.
Communication Path		A communication path is an association between two deployment targets, through which they are able to exchange signals and messages.
