Introduction
If you have bought or are considering buying this book, you probably fit one of the following categories:
l You know how valuable A+ Certification is to a professional personal computer (PC) technician's career and advancement.
l You're wondering just what A+ Certification is all about.
l You think that reading this book may be a fun, entertaining way to learn about computer hardware maintenance and repair.
l You love all … For Dummies books and wait impatiently for each new one to come out.
l You're a big fan of mine and can't wait to read all of my new books.
Well, if you fit any of the first four scenarios, this is the book for you! However, I'm not certified in the appropriate medical areas to help you if you are in the last category! If you're already aware of the A+ Certified Computer Technician program and are just looking for an excellent study aid, you can skip the next few sections of this introduction because your search is over.
However, if you don't have the foggiest idea of what A+ Certification is, how it can benefit you, or how to prepare for it, read on!
Why Use This Book?
With over 20 years and layer upon layer of microcomputer hardware and software technology to study, even the most knowledgeable technician needs help getting ready for the A+ exams. This book is intended to shorten your preparation time for the A+ exams. This book is a no-nonsense reference and study guide for the A+ Core Hardware exam (test #220-201) and the OS (Operating Systems) Technologies exam (test #220-202). It focuses on the areas likely to be
on the exam, plus it provides background information to help you understand some of the more complex concepts and technologies. The concepts, processes, and applications on the exams are presented in this book in step-by-step lists, tables, and figures without long explanations. The focus is on preparing you for the A+ exams, not on my obviously extensive and impressive knowledge of computer technology (nor on my modesty, I might add). This book will not provide you with an in-depth background on PC hardware and software. It will, however, prepare you to take the A+ Core Hardware and OS Technologies exams. In developing this book, I made two assumptions:
- You have knowledge of electronics, computers, software, networking, troubleshooting procedures, and customer relations, and need a study guide for the exams.
- You have limited knowledge of electronics, computer hardware, and the processes used to repair, maintain, and upgrade PCs and could use a little refresher on the basics along with a review and study guide for the exams.
If my assumptions in either case suit your needs, then this book is for you.
