The research of information technology includes science, technology, engineering and management, the application of these disciplines in information management, transmission and processing, related software and equipment and their interaction.
The application of information technology includes computer hardware and software, network and? Communication technology, application software development tools, etc. Since the popularization of computers and the Internet, people have increasingly used computers to produce, process, exchange and disseminate various forms of information (such as books, business documents, newspapers, records, movies, TV programs, sounds, graphics, images, etc.). ).
According to the different basic links in the workflow, information technology can be divided into? Information acquisition technology? Information transmission 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, meteorological satellites, thermometers, clocks, Internet searchers and so on. Information transmission technology refers to the technology of sharing information across space and can be divided into different types.
Such as directional transmission and bidirectional transmission technology, single channel transmission, multi-channel transmission and broadcast transmission technology. Information storage technology refers to the technology of saving information across time, such as? Print? Photography, audio recording, video recording, microfilm, magnetic disk, optical disk, etc. Information processing technology is a technology that describes, classifies, arranges, transforms, condenses, expands and innovates information. There are two breakthroughs in the development of information processing technology: from human brain information processing to the use of mechanical equipment (such as abacus and ruler). ) information processing, and then use it? Computer and network process information.
Information standardization technology refers to the organic connection and perfection of information acquisition, transmission, storage and processing. Information exchange * * * Ability to enjoy technology. Such as information management standards, character coding standards, language standardization, etc.
