Huge thanks go out to my editor, Brett Bartow, and all the other professionals at Pearson IT Certification. It is my great pleasure to have been associated with you for the past eight years, and I look forward to more exciting projects in the future.

My director at SkillSoft, Dan Young, has been super-supportive of my writing efforts, and I extend my gratitude to him.

Thanks to my technical editors, Michelle Plumb and Theodor Richardson. In a book such as this, with all of its terminology, Im grateful that you guys were looking over my shoulder and pointing out errors.

In the section, I mentioned my wife, Vivian. I once again want to acknowledge her. Being the parents of two teenage daughters can be time-intensive, and she is always willing to take on more than her fair share so that I can immerse myself in writing.

Speaking of our girls, Stacie and Sabrina, I also want to acknowledge you two. I am very proud of the young ladies you are becoming. Your character and your love for God are an inspiration to others.

As Ive grown in my own personal faith, Ive discovered that my spiritual gift is teaching. The book you now hold in your hands is a manifestation of that gift. My desire is to be a good steward of that God-given gift. So, with His guidance and continued blessings, I plan to continue demystifying complex concepts to my students and readers.

Albert Einstein once said, If you cant explain it simply, you dont understand it well enough. My goal for you, the reader, is that you will understand the concepts in this book so well, you will be able to explain them simply to others.

Michelle Plumb is a full-time Cisco certified instructor for SkillSoft. Michelle has 22+ years of experience in the field as an IT professional and telephony specialist.
