Introducción:En los últimos años el avance en las telecomunicaciones a nivel mundial experimenta un vertiginoso desarrollo; el acceso a Internet y la necesidad de más y mejores servicios como redes, telefonía, video conferencia, servicios electrónicos, demótica, etc., han impulsado el desarrollo de servicios de telecomunicaciones muchos de los cuales se encuentran basados en tecnología IP (Internet protocolo) y por consiguiente el desarrollo de nuevas tecnologías que ofrezcan estos servicios. Los esfuerzos que se realizan en el mundo para llevar servicios de telecomunicaciones a toda la población de las diferentes regiones de un país y poder lograr los objetivos de masificación del acceso a Internet, constantemente se ven enfrentados a la poca infraestructura disponible para ello, bien sea por las características geográficas de la zona o por viabilidad económica para los proveedores de dichos servicios, situación que es mas evidente en los países en vía de desarrollo, como es el caso de Colombia...

A new framework for assessing the role of information and communication technologies in development that draws on Amartya Sen's capabilities approach. Information and communication technologies (ICTs)--especially the Internet and the mobile phone--have changed the lives of people all over the world. These changes affect not just the affluent populations of income-rich countries but also disadvantaged people in both global North and South, who may use free Internet access in telecenters and public libraries, chat in cybercafes with distant family members, and receive information by text message or email on their mobile phones. Drawing on Amartya Sen's capabilities approach to development--which shifts the focus from economic growth to a more holistic, freedom-based idea of human development--Dorothea Kleine in Technologies of Choice? examines the relationship between ICTs, choice, and development. Kleine proposes a conceptual framework, the Choice Framework, that can be used to analyze the role of technologies in development processes. She applies the Choice Framework to a case study of microentrepreneurs in a rural community in Chile. Kleine combines ethnographic research at the local level with interviews with national policy makers, to contrast the high ambitions of Chile's pioneering ICT policies with the country's complex social and economic realities. She examines three key policies of Chile's groundbreaking Agenda Digital: public access, digital literacy, and an online procurement system. The policy lesson we can learn from Chile's experience, Kleine concludes, is the necessity of measuring ICT policies against a people-centered understanding of development that has individual and collective choice at its heart.

In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.
