The Encyclopaedic Dictionary of Computer Science, the first of its kind in India, has been complied to meet the needs of the increasingly large number of those who have to deal with different aspects of computerization in colleges, universities, industry, commerce and government. This dictionary provides a speedy means of reference to easily interpreted definitions of the terms taken from computers, data processing (e.g., micro, mini and main frame computers), communications(e.g. data networks broadcasting, satellite systems), office systems (e.g. copiers, micro computers, word processor systems), information system (e.g. copiers, micro computers, word processor systems), information systems (e.g. copiers, micro computers, word processor system), information systems (e.g.videotex, teletext, on-line data base) plus microelectronics, graphics, printing and consumer electronics. This dictionary provides authoritative, comprehensive, up-to-data and readable reference aids, each complied and edited by established professionals. This approach, combined with an extensive cross-referencing system, enables the reader to place each entry into a broader scientific context. Drawings have been introduced to convey meaning of terms at appropriate places.

This book examines and analyses as it surveys the role and impact of science and technology in the development of the country. What are Independent India's achievements in the various fields of science and technology during the last fifty years (1947-1997). This book highlights as how far India has benefited from S&T developments particularly the common people especially the rural population or contributed to social transformation.

In today's world it is imperative to achieve self reliance in scientific research in certain crucial areas, for progress is closely related to the Technological status of a country. The crucial areas in which India's development has been phenomenal are mentioned in this book. In our offices and homes, in factories and hospitals, in farmlands and battle fields, in the sky and in the oceans, Indians have witnessed an explosion of ingenuity that would have been beyond the comprehensions of previous generation.

Here is a vital and vivid presentation of the landmarks of past fifty years in Science & Technology in India.
