book includes:

■ Additional instructional material to assist in class preparation, including suggestions

for classroom activities, discussion topics, quizzes, and additional exercises.

■ Solutions to all end-of-chapter materials, including the Review Questions and

Discovery Exercises.

ExamView

. This textbook is accompanied by ExamView, a powerful testing software pack-

age that allows instructors to create and administer printed, computer (LAN-based), and

Internet exams. ExamView includes hundreds of questions that correspond to the topics cov-

ered in this text,enabling students to generate detailed study guides that include page references

for further review. The computer-based and Internet testing components allow students to take

exams at their computers and save the instructor time by grading each exam automatically.

PowerPoint presentations. This book comes with Microsoft PowerPoint slides for each

chapter.These are included as a teaching aid for classroom presentation, to make available

to students on the network for chapter review, or to be printed for classroom distribution.

vided on the Instructor’s Resource CD.

System Requirements

The following system requirements are recommended to install Fedora Core 6 which

comes with this book:

■ A high-end Intel/AMD-class computer that operates at 500 MHz or faster

■ 128 MB of RAM or more (more is preferred for faster response)

■ At least 5 GB of disk space (to install X Window interfaces and applications)

Read This Before You Begin

There are several ways to set up a lab for the hands-on projects in this text. One is to pro-

vide students with their own PCs equipped with a Linux operating system, such as

Fedora.This enables students to have the full experience of working with UNIX/Linux,

including access to the X Window interface and the GNOME or KDE desktops.

Another way to perform the hands-on activities in this book is to provide students with

access to a computer running Linux, such as Fedora, Red Hat Enterprise Linux, or SUSE

that is configured as a server and connected to a network. Students can access the server

remotely from a networked lab equipped with computers running a Microsoft Windows

operating system, UNIX/Linux, or Mac OS X, and using the Telnet or SSH capabilities

built into these systems. Students can also use computers with any of these operating sys-

tems and access the server over an Internet connection from a lab or from home.

Yet another way to perform the hands-on activities is for students and readers to install

on their own computers the Fedora Core 6 operating system that accompanies this book

on a DVD. The book also comes with the Knoppix CD that requires no installation,

because it runs from a CD/DVD drive. Students can conveniently use the Knoppix CD

on their own computers or on computers in a lab, without installing anything—so the

computer is not altered in any way. A few projects cannot be completed via the Knoppix

CD, which are those in Chapter 3 involving the Emacs editor and the GNOME desktop

projects in Chapter 11.The Knoppix CD does, however, enable students and readers to

complete the projects in Chapter 11 for the KDE desktop.
