What is Information Technology?

Information Technology (abbreviated IT), is a general term for a variety of technologies employed primarily to manage and process information. It focuses on the application of computer science and communications technology to the design, development, installation and implementation of information systems and application software. It is also often referred to as Information and Communications Technology (ICT). It mainly includes sensing technology, computer technology and communication technology.

The study of information technology encompasses the disciplines of science, technology, engineering, and management; the application of these disciplines to the management, transfer, and processing of information; and the associated software and devices and their interactions.

The applications of information technology include computer hardware and software, networking and? communication technologies, application software development tools, etc. Since the popularization of computers and the Internet, it has become increasingly common to use computers to produce, process, exchange, and disseminate various forms of information (e.g., books, business documents, newspapers, recordings, movies, television programs, speech, graphics, images, etc.).

By the basic aspects of the workflow, information technology can be categorized as ? information acquisition technology, ? information transfer technology, information storage technology, information processing technology and information standardization technology. Information acquisition technology includes information search, perception, reception, filtering and so on. Such as microscopes, telescopes, weather satellites, thermometers, clocks, Internet searchers in the technology. Information transfer technology refers to the technology of enjoying information across space ****, and can be divided into different types.

As in the direction of transmission and two-way transmission technology, single-channel transmission, multi-channel transmission and broadcast transmission technology. Information storage technology refers to the technology of preserving information across time, such as ? Printing,? Photography, audio recording, video recording, microfilming, disk technology, CD-ROM technology and so on. Information processing technology is the technology of describing, categorizing, sorting, converting, condensing, expanding and innovating information. The development of information processing technology has been two breakthroughs: from the human brain information processing to the use of mechanical equipment (such as the abacus, ruler, etc.) for information processing, and then the development of the use of? Electronic computers and networks for information processing.

Information standardization technology refers to the acquisition of information, transmission, storage, processing of all aspects of the organic convergence, and improve the ? Information exchange **** enjoy the ability of technology. Such as information management standards, character coding standards, standardization of language and writing.
