Information technology (IT, and - information and communication technologies - the processes, methods of search, collection, storage, processing, supply, distribution of information and ways to implement such processes and methods methods, techniques and methods of application of computer technology in the performance of functions of collecting, storing, processing, transmission and use; the resources required for the collection, processing, storage and dissemination of information.
Specialists in the field of information systems and technologies are often called IT or IT-specialists.
The discipline of Information Technology
Broadly speaking, the IT cover all areas of creation, transmission, storage and reception of information, not limited to computer technology. At the same time IT is often associated with computer technology, and this is no accident: the emergence of computers has brought IT to the next level, as once TV, and even before printing.
The information technology industry
The information technology industry is engaged in the creation, development and operation of information systems. Information technologies are designed based and rational use of modern advances in computer technology and other high-tech, new media, software and practical experience to solve problems for the efficient organization of the information process to reduce the amount of time, labor, energy and material resources in all areas human life and modern society. Information technology interact, and often an integral part of part of the service industry, management, manufacturing, social processes.
The main features of modern IT
1. Structured data exchange standards for digital algorithms;
2. The widespread use of computer conservation and the provision of information in the required form;
3. Transmission of information by means of digital technologies on almost unlimited distances.
Technologies
Information technology includes all the resources needed to manage information, especially computers, software, and network necessary for the creation, storage, management, sharing and retrieval of information. Information technology can be grouped as follows:
1. network
2. terminals
3. services
Network
urrently, there are various data networks - combined endpoints (terminals) communications, united by data channels and switching devices (network nodes) that provide messaging between all terminals.
1. The following types of data networks:
2. Telephone networks - subscriber communication network to access that uses telephone sets, PBXs and data equipment.
3. Computer networks - networks, terminals which are computers.
