By definition, the world Information Technology is a set of interrelated technical, scientific and engineering disciplines, designed to explore the most effective organization of people working to ensure storage and processing of information, computing, and methods of organization and interaction of the production equipment with people, the practical application of this equipment.
Information technology is becoming part of the lives of modern man every year more and more. This revolution that evaded lives of people in barely a decade, requires a multi-level information technology training, considerable initial costs and high-tech equipment because the introduction of computer systems begins with mathematical software, creation of information flows in the system of training.
IT usually means computer technology, as information technology work related to exploitation of computers and software to store, process, protect, receive and impart information. Specialists in the field call those people associated with this science as IT professionals.
In a broad sense as the term "information technology" encompasses not only the computer, but all of the transfer, storage and use of information. The appearance of electronic computers has brought a new level of IT.
IT development is considered to be from the 60 years of the twentieth century with the advent of information systems (IS). Organizational information system called an ordered set of interrelated IT tools and techniques that are used to process, store and retrieve information. The main technical tool in computers realizes date entry and processes it to form information for decision-making tasks in any area.
Performance of the functions of IP is not possible without knowledge of its IT-oriented. IT, in turn, can exist outside the sphere of information systems. Consequently, the concept of "information technology" is more capacious, as it reflects the current understanding of the transformation of the information society.
