Acknowledgments
First, we would like to thank our students. We constantly learn from them while teaching, and they are a continual source of inspiration and new ideas.
We could not have written this book without the loving support of our families. Our spouses and children made sacrifices (mostly in time not spent with us) to permit us to make this dream into a reality.
Although working with the entire team at Pearson has been a truly enjoyable experience, a few individuals deserve special mention. The constant support and encouragement we receive from Jenifer Niles, Executive Portfolio Product Manager, and Andrew Gilfillan, VP, Editorial Director, continually make this book grow and change. Our heartfelt thanks go to Shannon LeMay-Finn, our Developmental Editor. Her creativity, drive, and management skills helped make this book a reality. We also would like to extend our appreciation to Pearson Content Producers, particularly Laura Burgess, and the vendor teams, who work tirelessly to ensure that our book is published on time and looks fabulous. The timelines are always short, the art is complex, and there are many people with whom they have to coordinate tasks. But they make it look easy! We’d like to extend our thanks to the media and MyLab IT team—Eric Hakanson, Becca Golden, Amanda Losonsky, and Heather Darby for all of their hard work and dedication.
There are many people whom we do not meet at Pearson and elsewhere who make significant contributions by designing the book, illustrating, composing the pages, producing the media, and securing permissions. We thank them all.
And finally, we would like to thank the reviewers and the many others who contribute their time, ideas, and talents to this project. We appreciate their time and energy, as their comments help us turn out a better product each edition. A special thanks goes to Rick Wolff, a wonderfully talented infographic designer who helped by creating the infographics for this text.

Our 15th Edition—A Letter from the Authors
Why We Wrote This Book
The pace of technological change is ever increasing. In education, we have seen this impact us more than ever recently—the Maker movement, MOOCs, touchscreen mobile delivery, and Hangouts are now fixed parts of our environment.
Even the most agile of learners and educators need support in keeping up with this pace of change. We have responded by integrating material to help students develop skills for web application and mobile programming. We see the incredible value of these skills and their popularity with students, and have included Make This exercises for each chapter. These exercises gently bring the concepts behind mobile app development to life. In addition, there is a Solve This exercise in each chapter that reinforces chapter content while also applying Microsoft Office skills. These projects help to promote students’ critical thinking and problem-solving skills, which employers highly value.
We have introduced eight new Helpdesk training modules and two new IT Simulations to continue to provide students with an active learning environment in which they can reinforce their learning of chapter objectives. In addition, in this edition we have focused more on artificial intelligence and its impact on how we will use technology ethically. We also continue to emphasize the many aspects of ethics in technology debates. Some of the new Helpdesks and IT Simulations support instruction on how to conduct thoughtful and respectful discussion on complex ethical issues.
Our combined 50 years of teaching computer concepts have coincided with sweeping innovations in computing technology that have affected every facet of society. From iPads to Web 2.0, computers are more than ever a fixture of our daily lives—and the lives of our students. But although today’s students have a much greater comfort level with their digital environment than previous generations, their knowledge of the machines they use every day is still limited.
Part of the student-centered focus of our book has to do with making the material truly engaging to students. From the beginning, we have written Technology in Action to focus on what matters most to today’s student. Instead of a history lesson on the microchip, we focus on tasks students can accomplish with their computing devices and skills they can apply immediately in the workplace, the classroom, and at home.
We strive to keep the text as current as publishing timelines allow, and we are constantly looking for the next technology trend or gadget. We have augmented the text with weekly technology updates to help you keep on top of the latest breaking developments and continue to include a number of multimedia components to enrich the classroom and student learning experience. The result is a learning system that sparks student interest by focusing on the material they want to learn (such as how to integrate computing devices into a home network) while teaching the material they need to learn (such as how networks work). The sequence of topics is carefully set up to mirror the typical student learning experience.
As they read through this text, your students will progress through stages and learning outcomes of increasing difficulty:
1. Thinking about how technology offers them the power to change their society and their world and examining why it’s important to be computer fluent
2. Understanding the basic components of computing devices
3. Connecting to and exploring the Internet
4. Exploring application software
5. Learning the operating system and personalizing their computer

JOURNAL DE
Le Journald'EugèneDelacroixse compose de notes prises au jour le jour, écrites à bâtons rompus, où le grand artiste jetait chaque soir au courant de la plume, sans ordre, sans plan, sans transitions, toutes les idées, les réflexions, les théories, les extases, les découragements qui pouvaient traverser son esprit toujours en travail.
Commencé en 1823 par un jeune homme de vingt-deux ans, dans la fièvre d'une vie ardente et tourmentée, ce Journal a d'abord l'allure rapide et quelque peu décousue; à mesure que les années s'avancent, le sang s'apaise, l'esprit se mûrit et s'élève, l'expérience naît, l'horizon s'élargit, le style se précise et les aperçus succincts du début font place peu à peu à de véritables morceaux littéraires.
Ces notes qui n'étaient pas destinées à voir le jour et qui embrassent une période de plus de quarante années, se trouvent consignées sur une série de petits cahiers, de calepins et d'agendas portant chacun sa date.
L'existence de ce Journal était connue: des copies en furent prises; à la mort de Delacroix, elles demeurèrent entre les mains de l'élève le plus fidèle, du véritable disciple du maître, le peintre Pierre Andrieu, à qui nous devons rendre ici un sincère hommage. La vénération d'Andrieu pour Delacroix avait revêtu le caractère d'une véritable religion: dépositaire de la pensée du grand peintre, il résolut de la garder pour lui seul, et, tant qu'il vécut, il se refusa à publier ces pages qu'il relisait sans cesse.
Pierre Andrieu est mort l'an dernier. Sa veuve et sa fille n'ont pas cru devoir priver plus longtemps le public d'un document si précieux pour l'histoire de l'art, et elles nous ont confié la mission de le mettre au jour.
La publication actuelle est donc faite d'après les papiers remis à Pierre Andrieu. Mais pour écarter toute critique, éviter toute erreur et assurer à la pensée de l'écrivain toute son exactitude et toute son autorité, les éditeurs ont pensé qu'il était indispensable de contrôler ces notes, page par page, sur les manuscrits originaux. Le petit-
neveu du grand peintre, M. de Verninac, sénateur du Lot, avec une bonne grâce et une courtoisie dont nous ne saurions trop le remercier, nous a permis de faire ce travail de vérification sur les originaux eux-mêmes, qu'il a bien voulu nous communiquer.
Si dans ce Journal certaines lacunes sont à constater, notamment pour la période de 1848, par contre nous avons eu la bonne fortune de retrouver certains carnets qu'on croyait égarés. Le fameux voyage au Maroc, dont la trace semblait perdue, appartient aujourd'hui à M. le professeur Charcot, qui nous a permis de reproduire cet épisode capital dans la carrière artistique du maître; nous sommes heureux de pouvoir lui adresser ici l'expression de notre gratitude.
Nous avons fait également appel au souvenir des anciens amis, des élèves et des admirateurs de Delacroix; tous se sont empressés de mettre à notre disposition les renseignements et les documents qu'ils pouvaient posséder. En nous accordant leur bienveillant concours, Mme Riesener, M. le marquis de Chennevières, MM. Robaut, Faure, Paul Colin, Maurice Tourneux, Monval, Bornot, le commandant Campagnac, nous ont aidés dans notre tâche, et c'est un devoir pour nous d'inscrire leurs noms en tête de cette publication.
Pour conserver au Journal son véritable caractère, les éditeurs ont scrupuleusement respecté les divisions du manuscrit, qu'ils publient tel qu'il a été conçu. À côté des aperçus philosophiques, des idées critiques les plus élevées, sur l'art, sur la peinture, la musique et la littérature, on trouvera une foule de notes personnelles qui nous font pénétrer dans la vie même de l'artiste; car Delacroix a consigné dans ces cahiers tous les détails de son existence, jusqu'aux incidents parfois infimes de sa journée, ses visites, ses promenades, voire même ses dépenses, le prix de vente de ses tableaux et les procédés techniques de sa peinture. Tous ces menus faits, dont quelques-uns pris isolément pourraient paraître quelquefois de peu de valeur, constituent, réunis, un document du plus haut intérêt: il en ressort un Delacroix intime, qu'on avait pu soupçonner déjà par la correspondance recueillie par Philippe Burty et par les notes
