): threat to society 2. 7 Information society Post industrial society in which most of the people are involved in the business of information Transformation from industrial society to information society After discovery of modern computer: main tool for information society Computer technology is to information age what mechanization was to the industrial revolution.In computer age, we are dealing with the conceptual space connected by electronics rather than physical space connected by motor car Combined technology of telephone, computer and television have merged into an information and communication system Information economy.
