Synopsis The twentieth century witnessed the rapidly accelerating advent of information technology. The electronic communications and news media have become commonplace and indispensable; computers have proliferated, becoming increasingly fast, powerful, small and cheap, so that now there is scarcely a human activity in which they are not to be found, bearing an increasing share of the burden of repetitive information processing. This book elaboratively discusses the challenges and opportunities of information technology in the new millennium. It will prove highly informative to all the media persons and students and teachers in the field of information technology.
