Information Technology consists of all forms of technology used to create, store and exchange information in various forms, i.e. it incorporates all computerized and automated information handling including system design and analysis, conversion of data, computer programming, information storage and retrieval, voice, video and data communications.
Over the last decade, organizations worldwide have transformed the way they do business by investing millions of dollars in IT. Today information technology is not just computer literacy. It also takes into account how computers work and how these computers can further be used not just for information processing but also for communications and problem solving tasks as well. The impact of information technology has been felt all over the world and in all areas of life like Education, Entertainment, Scientific Applications, Artificial Intelligence and Robotics etc.
