Wrap-Up

This chapter introduced basic hardware and software concepts and basic object technology concepts, including classes, objects, attributes and behaviors. We discussed the different types of programming languages and which languages are most widely used. We presented a brief history of operating systems, including Microsoft's Windows operating system. We discussed the history of the Internet- and the Web. We presented the history of C# programming and Microsoft's .NET initiative, which allows you to program Internet and Web-based applications using C# (and other languages). You learned the steps for executing a C# application. You test-drove a sample C# application similar to the types of applications you will learn to program in this book. You learned about the history and purpose of the UMLthe industry-standard graphical language for modeling software systems. We launched our early objects and classes presentation with the first of our "Software Engineering Case Study" sections (and the only one which is required). The remaining (all optional) sections of the case study use object-oriented design and the UML to design the software for our simplified automated teller machine system. We present the complete C# code implementation of the ATM system in Appendix J.

In the next chapter, you will use the Visual Studio IDE (Integrated Development Environment) to create your first C# application using the techniques of visual programming. You will also learn about Visual Studio's help features.
