Welcome to the
CompTIA A+ Complete Study Guide.
This is the fourth edition of our bestselling
study guide for the A+ certification sponsored by CompTIA (Computing Technology
Industry Association).
This book was written at an intermediate technical level; we assume that you already know how
to
use
a personal computer and its basic peripherals, such as modems and printers, but we also
recognize that you may be learning how to
service
some of that computer equipment for the first
time. The exams cover basic computer service topics as well as some more advanced issues, and
they cover some topics that anyone already working as a technician, whether with computers or
not, should be familiar with. The exams are designed to test you on these topics in order to certify
that you have enough knowledge to fix and upgrade some of the most widely used types of
personal desktop computers.
We’ve included review questions at the end of each chapter to give you a taste of what it’s
like to take the exams. If you’re already working as a technical service or support technician,
we recommend you check out these questions first to gauge your level of knowledge. (You can
also take the Assessment Test at the end of this Introduction, which is designed to see how
much you already know.)
Don’t
just study the questions and answers—the questions on the actual exams will be different
from the practice ones included in this book and on the CD. The exams are designed to test your
knowledge of a concept or objective, so use this book to learn the objective
behind
the question.
You can use the book mainly to fill in the gaps in your current computer service knowledge.
You may find, as many PC technicians have, that being well versed in all the technical aspects
of the equipment is not enough to provide a satisfactory level of support—you must also have
customer-relations skills. We include helpful hints to get the customer to help you help them.
