UML is used to model an application structures, behavior and even business processes A component diagram displays the structural relationship of components of a software system. Often, this is done by using CASE tools (Computer Aided Software Engineering Tools). It only represents the internal structure of a class and the relations between different class components. Check out this wiki article to learn more about the dependencies and elements found in package diagrams. To be more specific, with deployment diagrams we can construct a physical model of how software components (artifacts) are deployed on hardware components, known as nodes. This is a very helpful overview with manyuseful links. It’s very help the learner, thank u much. Unless you can roll out improvements easily - you won't see any benefits.

State machine UML diagrams, also referred to as Statechart diagrams, are used to describe the different states of a component within a system.
