Examples of components for component diagrams are:

o        Main program, i.e. the Java file that contains the root of the program (the function main())

o        Package, that contains a number of classes

o        Subprograms, modules that correspond to subroutine declarations

o        Tasks, modules that represent packages with independent threads of control

An example of a deployment diagram could be a client/server architecture. (See [Fowler, 2000a] for another example).
