Our modern connected world depends on fast and efficient networks to operate. Without global data networks modern society would come to an abrupt halt. There would be no email, no internet access, no mobile phones and no financial services. Supply systems for utilities such as gas, electric and even water would cease to operate. Our world as we have become used to it would cease to function. Networking has changed our political, economic and social landscapes, drastically redefining government and the rule of law while intimately reshaping our personal lives. The pace of change continues to accelerate and if you don't understand the fundamentals behind these changes you risk either being left behind or missing out on the new opportunities these changes afford. This book contains all the information you need to know on networking, from its history, to the underlying technologies and technical theory explaining how it operates, to an in-depth look at cloud computing, online security, VOIP (Voice over Internet Protocol), wireless and mobile connectivity and much more. This book also contains mini biographies of 12 of the leading figures in the history of networking, some of these stories are surprising and inspirational whilst others are far more tragic. Winner of the 'World Reading Day' Non-Fiction book of the year, The Book on Networks is a must read for anyone who either works in Information Technology or has an interest in understanding the realities behind how our modern connected world works.
