those stars arent for how much i liked this book, really. at least not reading it because technical jargon gets to me real quick! it does, however, explain a lot. if you'd like to learn more about understanding your pc and others, this is a must.
there are references & a resource guide; online website with quizzes, study guides, crossword puzzles, glossary & other links to explore. this IS a college text book...a real learning tool!
