Introduction: A+ Guide to Managing

and Maintaining Your PC

A+ Guide to Managing and Maintaining Your PC, Eighth Edition was written to be the very

best tool on the market today to prepare you to support personal computers Updated to

include the most current hardware technologies, this book takes you from the just-a-user level to

the I-can-fi x-this level for PC hardware and software matters This book achieves its goals with

an unusually effective combination of tools that powerfully reinforce both concepts and

hands-on, real-world experiences It also provides thorough preparation for the hardware content on

the new 2012 CompTIA A+ Certifi cation exams Competency in using a computer is a

prereq-uisite to using this book No background knowledge of electronics is assumed An appropriate

prerequisite course for this book would be a general course in microcomputer applications

This book includes:

Several in-depth, hands-on projects are spaced throughout each chapter that invite you to

immediately apply and reinforce skills and are designed to make certain that you not only

understand the material, but also execute procedures and make decisions on your own

Comprehensive review and practice end-of-chapter material, including a chapter

summary, key terms, review questions that focus on A+ content, critical thinking

questions, and real-world problems to solve

Step-by-step instructions on installation, maintenance, optimization of system

per-formance, and troubleshooting

Online video clips featuring Jean Andrews illustrating key points from the text to aid

your understanding of the material

A wide array of photos, drawings, and screen shots support the text, displaying in detail the

exact hardware features you will need to understand to manage and maintain your PC

In addition, the carefully structured, clearly written text is accompanied by graphics

that provide the visual input essential to learning For instructors using the book in a

classroom, instructor resources are available online and on the Instructor Resources CD

Coverage is balanced—while focusing on new hardware and software, the text also

cov-ers the real work of PC repair, where some older technology remains in widespread use

and still needs support For example, the book covers how to use a 64-bit operating system

to support the latest processors, but also addresses how to get the most out of a 32-bit OS

with limited hardware resources At the time of writing this book, Windows 7 is the

cur-rent Microsoft operating systems used on desktop and laptop computers The book focuses

on supporting Windows 7 systems, while also including light coverage of Windows Vista in

Appendix B, and XP in Appendix C The book also covers other new technologies such as

virtualization, quad-channel memory, home theater systems, and cellular connections, but

also addresses using older technologies like PCI expansion slots, DDR2 memory, and impact

printers because many individuals and businesses still use these older technologies To rein

in the physical size and weight of the book, most of the content on less signifi cant and older

technologies has been placed on the web site that accompanies the book There you will fi nd

content on Linux, Mac OS, Windows 2000/XP, SCSI, the hexadecimal number system,

elec-tricity, multimeters, and legacy motherboards, hard drives, and processors

This book provides thorough preparation for CompTIA’s A+ 2012 Certifi cation

examinations This certifi cation credential’s popularity among employers is growing

exponentially, and obtaining certifi cation increases your ability to gain employment

and improve your salary To get more information on A+ certifi cation and its

sponsoring organization, the Computing Technology Industry Association,
