    Are you an entry-level IT professional with the equivalent knowledge of at least 500 hours of hands-on experience in the lab or field? If you are, then this book is for you! Authors Mark Edward Soper, David L. Prowse and Scott Mueller, have done an outstanding job of writing a 3rd edition of a book that will help you pass the 2012 version of the CompTIA A+ Certification exams 220-801 and 220-802. Authors’ Soper, Prowse and Mueller, begin with a introduction to most of the objectives found in 220-801 Domain 1 and 220-802 Domain 4, and provide a guide to where to find more detailed information elsewhere in this book. Next, they discuss some of the core components of the computer (the guts of the computer), including the motherboard and CPU. The authors also show you how the BIOS, CMOS and batteries on the motherboard interact and configure and upgrade the BIOS. They continue by delving into how power is conveyed to the computer, which power supply to select depending on your configuration and needs, how to install and troubleshoot power supplies, and how to cool the system. Next, the authors focus on the types, installation, and troubleshooting of RAM. They also discuss USB, FireWire, serial, parallel, SCSI, audio, and PS/2 keyboard and mouse ports; the goal here is to make you proficient with the various interfaces you will see in the IT field. The authors continue by helping you prepare for the A+ Certification exams by enhancing your understanding of the major types of video cards and displays; and, showing you how to install, configure, and troubleshoot them. Then, the authors discuss the specific requirements of each type of system and the guidelines for building or upgrading a system to meet them. Next, for the A+ exams, they show you the unique components of a laptop, how to safely remove and reinstall laptop hardware, the ports built in to a typical laptop, and how to troubleshoot laptops. The authors also show you how to operate the mobile devices and move ahead to the hardware and software that are propelling the devices into the mainstream. They continue by focusing on laser, inkjet, thermal and impact printers. Then, the authors show you what you need to know about storage devices. Next, they help you gain a foundation of knowledge about the possible installations and upgrades of Windows. The authors also discuss how to manage the Windows operating systems. They continue by helping you understand the common Windows-related problems and to master the tools and techniques necessary to solve them. Then, the authors discuss wired and wireless networking technologies, TCP/IP, network devices, and Internet connectivity options. Next, they help you master the A+ 220-802 exam objectives, which will result in you passing the exams and will also help you handle the increasing challenges of computer security in the real world. Finally, the authors discuss safety, the environment, response procedures and professional behavior. This most excellent book will help you master and understand the A+ Certification objectives. Perhaps more importantly, this great book uses a subsystem approach: each chapter is devoted to a particular part of the computer, so that you understand how the components of each part work together and how each part of the computer works with other parts.
