Introduction

Complete CompTIA A+ Guide to PCs, Sixth Edition, is intended for one or more courses geared

toward CompTIA A+ Certification and Computer Repair. It covers all the material needed for

the CompTIA A+ 220-801 and 220-802 exams. The book is written so that it is easy to read and

understand, with concepts presented in building-block fashion. The book focuses on hardware,

software, mobile devices, virtualization, basic networking, and security.

Some of the best features of the book include the coverage of difficult subjects in a

step-by-step manner, carefully developed graphics that illustrate concepts, photographs that

demonstrate various technologies, reinforcement questions, critical thinking skills, soft skills,

and hands-on exercises at the end of each chapter. Also, this book is written by a teacher who

understands the value of a textbook from someone who has been in IT their entire career.

What’s New in the Sixth Edition?

This update has been revised to include coverage of mobile devices such as smartphones and

tablets, virtualization, and design. This edition differs from the Fifth Edition Update book in

the following ways:

• Conformity with the latest CompTIA A+ Exam requirements, including the CompTIA

A+ 220-801 exam, as well as the CompTIA A+ 220-802 exam.

• A new chapter on computer design was added after the hardware chapters. The chapter

includes design activities with various scenarios.

• Mobile devices and virtualization technologies have been added to relevant hardware

and software chapters. Labs have also been included.

• Chapters 1 through 10 focus on hardware and design. Chapters 11 and 12 are the

operating system chapters. Chapter 13 and 14 cover Internet/networking concepts.

Chapter 15 handles security concepts.

• The Internet Connectivity chapter was moved after the Windows chapters and before

the Introduction to Networking chapter. The chapter was revamped to be a better

introduction to Internet technologies, before the book dives into the details of

supporting devices that connect to a wired or wireless network.

• Chapters 1 through 3 were reorganized to better flow through the basic concepts.

• The book has always been filled with graphics and photos, but even more have been

added to target those naturally drawn to the IT field.

• The number of questions at the end of each chapter was reduced, but more questions

are available in the test bank available from the Pearson Instructor Resource Center.

Organization of the Text

The text is organized to allow thorough coverage of all topics and also to be a flexible teaching

tool. It is not necessary to cover all the chapters, nor do the chapters have to be covered in

order.

• Chapter 1 covers beginning terminology and computer part and port identification.

Chapter 1 does not have a specific soft skills section as do the other chapters. Instead,

it focuses on common technician qualities that are explored in greater detail in the soft

skills sections of later chapters.

• Chapter 2 details components, features, and concepts related to motherboards,

including processors, cache, expansion slots, and chipsets. Active listening skills are

described in the soft skills section in this chapter.
