IT = Information Technology, Information Technology. IT = internet Technology, Internet technology. IT = International Tolerance, standard tolerances (International allows residues). IT = information theory, information theory. IT = instant translation, real-time translation. IT = initial test, the initial test. IT = income tax, income tax. IT = Imperial Tabacco, Imperial Tobacco (Group). IT = inclusive tour, package tour. IT = individual therapy, individual therapy. IT = innovative technology, innovation and technology. IT = inspiration technology, science and technology inspired, other IT, intertuberal diameter between the ischial tuberosity diameter, also known as export diameter (transverse outlet, TO) IT is the English definition of IT Information Technology, that is the meaning of the information industry, more widely: the current IT industry by way have a wide range, including the definition of the United States Department of Commerce is more clear and reasonable, it will be divided into all sectors of national economy and IT industry in the production of non-IT industry. Which are further divided into IT industry, IT industry, manufacturing industry and IT use. IT industry, manufacturing industry, including computer hardware, communications equipment, software, computer and communication services. As for the IT industry with almost all the sectors involved, including a greater proportion of services using IT. Thus, IT industry, not only refers to the communications industry, including hardware and software, not just manufacturing, but also related services, so that the communication industry is only part of the IT industry, IT industry,
air force one low nike, not all. The basic concept and scope of information technology, IT = informationtechnology actually has three levels:
CPU
The first layer is the hardware, mainly referring to data storage, processing and transmission of the host and network communication equipment; second level refers to the software include can be used to collect, store, retrieve, analyze, apply, evaluate the information of software, which includes our commonly referred to as ERP (enterprise resource planning), CRM (customer relationship management), SCM (supply chain management) and other commercial management software, also used to enhance process management for WF (workflow) management software, support of the DW / DM (data warehousing and data mining) software; the third layer is the application, refers to the collection, storage, retrieval, analysis , application, assessment using a variety of information, including application of ERP, CRM, SCM and other decision support software directly, but also by other decision-making model or with the DW / DM and other technical means to further improve the quality of the analysis, support decision-makers to make decisions ( to stress that only one decision aid and not a replacement). Some people understand the former two-story combined IT, integration refers to information storage, processing and transmission of information in the application of the latter; also after the story was the combined, then divided after the former hard-soft . Usually the third layer has not been given sufficient attention, but in fact it is only effective when the information value of IT applications to get into full play, and have real information to achieve the goal. Information itself is not a goal, it is only in the context of the current era of a good as a means to achieve its objectives. Carl's IT is it? In that article, which he did not explicitly put forward, but he referred to the core functions of information technology - data storage, processing and transmission. The logic of his reasoning, from the steam engine, railways, telegraph and telephone, electricity and other infrastructure to push over, but also with Moore's Law to support the development of the host and fiber. IT is often ambiguous concept: a moment that the host network, while another refers to the software. Information technology itself is only a tool, like a two-edged sword, or a good pen. Some concepts are often confused with the data (Data) = factual records, as indicated in a series of quarterly sales of products in the East China region 120 million. Information = (Information) = data + meaning, as indicated in a series of products quarter sales over last year in east China decreased by 25%. Intelligence (Intelligence) = information + understanding (understanding) and inference (reasoning), such as analysis of sales units in east China because no, or a series of products into a recession, or behind the company's overall marketing, sales lead strong competitors? Or other reasons. Knowledge (Knowledge) = problem-solving skills (skill), to solve this problem the company should the strategy? Wisdom (Wisdom) = the Selection (Selection) should be a variety of action programs, but the (strategic) to select which * wisdom. Action will then generate a new transaction data. Composition of the universal application of IT is a sign of the information society. Different people and different books have different explanations. But I think we all agree that a point is, IT has the following three components: ----- sensing technology, which is the human sense organs of the extension and expansion, the most obvious example is the bar code reader; ---- - Communication technology, which is the human nervous system extension and expansion, assume the function of transmitting information; ----- computer technology is an extension of human brain function and development, a commitment to information processing functions. The so-called information is the use of information technology to transform other industries and sectors, thereby enhancing the efficiency of enterprises. In this process, information technology, assumed the role of a powerful tool. By the way, what is meant by IT industry, there is a general classification, can be used for your reference: IT based technologies to provide IC research and development, software development, such as INTEL, MS IT technology products such as components, parts, components manufacturing, such as the elite, mass, etc. IT products, computers and peripherals integrated manufacturers such as Lenovo, IBM IT products system solutions, information systems such as Huawei, HP IT product distribution channels, marketing products and services such as Digital China IT consulting services and IT service industries, such as Blue Express opinion in support of IT type of media such as CCW, CCID IT industry needs support third-party services such as legal consulting services, PR services to a variety of IT back-up staff development institutions such as the computer industry cooperative organizations of professional IT associations, the entire assembly integration test cycle will systematically include software acceptance testing, end to end testing, the TV screen synthetic testing, system testing, user acceptance testing, more comprehensive testing and technical sports drills and so on. Its purpose is to ensure that the IT system has the necessary functions and reliability, smooth service for the Beijing 2008 Olympic Games.
