INFORMATION TECHNOLOGY
Information technology, a mix of computers and telecommunications, is concerned with storage, processing and transmission of information which is something people need for their advancement and well being. Information technology has brought the value of information to the level of consciousness. Information is now recognized as one of the three basic elements beside matter and energy that make up largely man-made environment and hence determine the quality of life. Information as a key factor to the socio-economic progress is increasingly gaining importance. Underlying this transformation is a process of radical technology change. The key issue is not simply the effects of automation based on rapidly developing computer technology. It is that new technologies which process information rather than physical resources provide the means for bringing radical changes in the socio-economic conditions by facilitating access to the information required to raise the productivity of industries and every sector of economy. Information technology has become the essential prerequisite for economic development and social progress.
Today, information has become an integral part of human life. It has a diversified role in socio-cultural, economic and political developments. In a fast developing country like India, availability of the latest information in science and technology and other fields need to be assured in the fastest and simplest forms. This is important because every developmental process depends on the availability of information. Nature and Role of Information. The word ?Information? has been derived from the Latin words ?formatio? and ?forma? meaning giving shape to something and forming a pattern respectively. Dictionaries define information as an action of telling, or fact of being told of something, - news, intelligence or knowledge. In the general sense of the term, information is found everywhere and all around us. Information is the staple diet of the readers of newspapers and mass audiences of the broadcasting media and the cinema. It is directed ceaselessly at those millions of consumers so relentlessly targeted by the advertising industry, and is dispensed round the clock from any number of enquiry desks at railway stations and airports, libraries and similar public or private service institutions. Role of Information in National Development. It has been already indicated that information is a basic resource for national development. Advancement of modern civilization requires that each member of the society is well-informed in matters relevant to our day-to-day living, because information is the basis of co-operative culture and steady development of the social being. However, an attempt has been made to illustrate it in the following dimensions:
E-Commerce : The year 1998 heralded not only the pre-eminence of the services sector but also the key role played by IT within that sector. Information services have become fundamental to the overall growth and development of the US economy. The most remarkable facet of the emerging ?digital economy? is of course electronic commerce (e-commerce). The internet, which enables e-commerce, is radically changing not only the way businessmen serve and communicate with their customers, but also the way they manage their relations with suppliers and partners. Both the new internet-based companies and the traditional producers of goods and services are transforming their businessmen processes into e-commerce processes in an effort to lower costs, improve customer service, and increase productivity. The value of e-commerce transactions worldwide is growing exponentially and is expected to reach US $3.2 trillion by the year 2003.INFORMATION TECHNOLOGY
