This revolution is far more sweeping than any other revolution in history in its reach and influence, bringing fundamental changes in all aspects of our lives. Information technology (IT) is the engine used to drive useful information systems. This includes computers, software, the Internet/ Intranet, and telecommunication systems. It provides the means for collecting, storing, encoding, processing, analyzing, transmitting, receiving, and printing text, audio, or video information. In the present context, IT is not merely a matter of machines and microchips. Now it regulates all aspects of our lives including how we live, how we work, how we communicate, how we relax, how we travel, and how we talk. This universal applicability of IT has made it the most important part of all technological curricula throughout the world. The future of IT promises to be more dynamic. Researchers in the field of processor performance, chip miniaturization, and other areas are setting up new standards every day. Keeping pace with these changing trends and to meet the requirements of modern curricula, all universities have integrated the study of IT in B.Tech., MCA, MBA, BCA, and B.Sc. courses.
