In this chapter, we addressed several issues related to keeping your system updated, installing and removing software, and protecting data. We also learned about package management. As you continue using Linux and JDS, you’ll find this information valuable. Your knowledge of the RPMs will have a direct bearing on how well your system performs.

Chapter 6 and Chapter 7 are where you can gain knowledge about JDS productivity applications. In these chapters, we introduce you to software you can in your everyday work life, including the web browser, email and personal information management, word processing, and instant messaging. As you progress into those chapters, you will find that the information learned in this chapter helps you understand JDS and how everything fits together architecturally.
