Böcker av Charles T. Meadow

Meadow takes us on a Cook's tour of communication technologies across time-the alphabet and moveable type printing, cave drawings and carrier pigeons, telephones, television and, of course, the Internet. In each case, Meadow shows how these (and other devices) are connected to each other, even as they serve to make connections between people. Part One discusses the basics of communications, while Part Two delves into telecommunications before the days of steam and electricity. Part Three offers insight into steam, electricity, and internal combustion energy and how they revolutionized society. Communication is the key to a productive world. For those dazzled by the pace of change in the technology or McLuhan's unorthodox but brilliant insights, Meadow's casual style and pace provide the perfect antidote.

A deep and penetrating exploration of the key concepts of information and communications sciences by one of its founders, this book covers everything in its subject that you want to know more about including the bedrock topics of signs, symbols, information, and communication, all considered from an historical and foundational perspective that is satisfying to the beginning student and worthwhile for practitioners of long standing. All the major players are given their role, from Shannon and Weaver to Tim Berners-Lee, with Marshall McLuhan an engaging participant. Communication in all its forms-be it print or electronic media, mass communication as well as person-to-person messaging, whether by mail, telephone, gesture, or email-is thoroughly examined in this book, which can serve as either an introductory text to undergraduates in information science, an interesting read for the layman, or as a refresher for the communications professional.

Dealing with computer-based retrieval systems, this book covers the nature of information, how it is organized for use by a computer, how search functions are carried out, and the theory underlying these functions. It also discusses the interaction between user and system and how retrieved items, users, and complete systems are evaluated.
