CompTIA A+ Certification Study Guide, Eleventh Edition (Exams 220-1101 & 220-1102)

Well, that's a nice question actually because you need to consider this book before buy.First thing:1. The book binding and printing is excellent; it's looks like you are preparing for a+ exam.2. The book has better details and summary.3. The book provides you with limited information on small topics such as VoIP, Mobile devices and some cabling system, etc. because everything is not covered.4. Don't think this book is enough for exam.Exam objectives are divided into many parts/chapters, and you have to search and read all the related topics which can be tiresome.So far, I would say buy this book as a reference or as it simply said "guide". I learned more about key ideas from watching Mike Meyers videos, which you should as an IT guy. Keep in mind that you have to practice, practice and practice all the questions from everywhere even if you don't want to.Also, always remember that no book can get you anywhere in IT until you try things with your own hands and fingers.Good Luck :)
