Below is a list of reading material that I’ve gone through and highly recommend.


CCNA Routing and Switching Complete Study Guide

by Todd Lammle

If your completely new to networking this is a great introduction to the subject. I really enjoyed Todd’s writing style, it was a pleasure to read. The review questions at the end of each chapter is a nice touch and a great way to see test how well you know the material. Unfortunately I can’t say the same for the ICND2 section. It wasn’t as thorough as I would liked it to have been and if you’re using the Cisco blueprint as your study guide this book can appear disjointed as it doesn’t follow it closely.

CCNA Routing and Switching 200-125 Official Cert Guide library

by Wendell Odom

If I only had one choice of material to use to study for and pass the CCNA Routing and Switching exam, this is hands down the best material on the subject. Wendell’s work is clear and very thorough. Being the official certification guide you would hope that it followed the blueprint and it does exactly that. He offers excellent study advice and I really liked the Do I Know It Already questions at the beginning of each chapter, I just wish there were more. If I had to give one piece of advice to tackle these mammoth books really invest in spaced repetition!

CCNA Routing And Switching Portable Command Guide

by Scott Empson

I discovered Scott’s portable command guide towards the very end of my studies via Safari Books Online and wish I had it from the beginning. This guide is fantastic for the ‘configure, verify, and troubleshoot’ sections of the Cisco exams. Go to your subject of interest and there’s zero fluff. You’ll find exactly what you need to get the job done. Where there are examples and tips they’re excellent and do not take away from the portable nature of this guide. If your having to configure a lot of equipment without the luxury of using SDN I can absolutely see how invaluable this book would be for that situation, unless of course you know it all off by heart.


Where Wizards Stay Up Late: The Origins of the Internet

by Katie Hafner, Matthew Lyon

“Where Wizards Stay Up Late” is the exciting story of the pioneers responsible for creating the most talked about, most influential, and most far-reaching communications breakthrough since the invention of the telephone. In the 1960’s, when computers where regarded as mere giant calculators, J.C.R. Licklider at MIT saw them as the ultimate communications devices. With Defense Department funds, he and a band of visionary computer whizzes began work on a nationwide, interlocking network of computers. Taking readers behind the scenes, “Where Wizards Stay Up Late” captures the hard work, genius, and happy accidents of their daring, stunningly successful venture.

The Idea Factory: Bell Labs and the Great Age of American Innovation

by Jon Gertner

From its beginnings in the 1920s until its demise in the 1980s, Bell Labs-officially, the research and development wing of AT&T-was the biggest, and arguably the best, laboratory for new ideas in the world. From the transistor to the laser, from digital communications to cellular telephony, it’s hard to find an aspect of modern life that hasn’t been touched by Bell Labs.

In The Idea Factory, Jon Gertner traces the origins of some of the twentieth century’s most important inventions and delivers a riveting and heretofore untold chapter of American history. At its heart this is a story about the life and work of a small group of brilliant and eccentric men-Mervin Kelly, Bill Shockley, Claude Shannon, John Pierce, and Bill Baker-who spent their careers at Bell Labs.

Today, when the drive to invent has become a mantra, Bell Labs offers us a way to enrich our understanding of the challenges and solutions to technological innovation. Here, after all, was where the foundational ideas on the management of innovation were born.

A Thread Across the Ocean: The Heroic Story of the Transatlantic Cable

by John Steele Gordon

Today, in a world in which news flashes around the globe in an instant, time lags are inconceivable. In the mid-nineteenth century, communication between the United States and Europe — the center of world affairs — was only as quick as the fastest ship could cross the Atlantic, making the United States isolated and vulnerable.

But in 1866, the Old and New Worlds were united by the successful laying of a cable across the Atlantic. John Steele Gordon’s book chronicles this extraordinary achievement — the brainchild of American businessman Cyrus Field and one of the greatest engineering feats of the nineteenth century. An epic struggle, it required a decade of effort, numerous failed attempts, millions of dollars in capital, a near disaster at sea, the overcoming of seemingly insurmountable technological problems, and uncommon physical, financial, and intellectual courage. Bringing to life an overlooked story in the annals of technology, John Steele Gordon sheds fascinating new light on this American saga that literally changed the world.

The Innovators: How a Group of Hackers, Geniuses and Geeks Created the Digital Revolution

by Walter Isaacson

The computer and the internet are among the most important innovations of our era, but few people know who created them. They were not conjured up in a garret or garage by solo inventors suitable to be singled out on magazine covers or put into a pantheon with Edison, Bell, and Morse. Instead, most of the innovations of the digital age were done collaboratively. There were a lot of fascinating people involved, some ingenious and a few even geniuses. This is the story of these pioneers, hackers, inventors, and entrepreneurs—who they were, how their minds worked, and what made them so creative. It’s also a narrative of how they collaborated and why their ability to work as teams made them even more creative.

Hackers: Heroes of the Computer Revolution

by Steven Levy

A mere fifteen years ago, computer nerds were seen as marginal weirdos, outsiders whose world would never resonate with the mainstream. That was before one pioneering work documented the underground computer revolution that was about to change our world forever. With groundbreaking profiles of Bill Gates, Steve Wozniak, MIT’s Tech Model Railroad Club, and more, Steven Levy’s Hackers brilliantly captured a seminal moment when the risk-takers and explorers were poised to conquer twentieth-century America’s last great frontier. And in the Internet age, the hacker ethic-first espoused here-is alive and well.
