We will be using software to draw a special type of diagrams called UML diagrams that represent software architecture. There are many types that are open source and available for free download. For example ArgoUML, Visual Paradigm, UMLet, Rational Rose and many others. Research these tools and decide which of them you would like to use. If you have used one of them before that is ok. The tool you choose should be a free-download. Submit the name of the tool that you are going to use and a simple diagram you can produce with it (easiest diagrams are Use Case Diagrams or Component Diagrams, we will discuss in class).
