Internet technology refers to information technology based on computer technology.
[Edit this paragraph] The concept and scope of technology
The first layer is hardware, which mainly refers to the host computer and network communication equipment used for data storage, processing and transmission; The second layer refers to software, including all kinds of software that can be used to collect, store, retrieve, analyze, apply and evaluate information. Including ERP (enterprise resource planning), CRM (customer relationship management), SCM (supply chain management) and other business management software, as well as WF (workflow) management software to strengthen process management and DW/DM (data warehouse and data mining) to assist analysis. The third layer refers to the application, which refers to the collection, storage, retrieval, analysis, application, evaluation and use of all kinds of information, including the application of ERP, CRM, SCM and other software to directly assist decision-making, and also including the use of other decision-making analysis models or the use of DW/DM and other technical means to further improve the analysis quality and assist decision-makers to make decisions (to emphasize one point, it only assists rather than replaces people's decisions). Some people understand that Internet technology combines the first two layers into one, which refers to the storage, processing and transmission of information, while the latter refers to the application of information. Some people combine the last two layers into one, which is divided into hard front and soft back. Usually, the third layer has not been paid enough attention, but in fact, only when information is effectively applied can its value be fully exerted and the goal of informatization be truly realized. Informatization is not an end in itself, but a better means to achieve the goal in the current era background. What does Carl mean by Internet technology? In that article, he didn't make it clear, but he mentioned the core functions of information technology-data storage, processing and transmission. From the logic of his reasoning, that is, from the infrastructure construction such as steam engine, railway, telegraph and telephone, electric power, Moore's law has also been used to prove the development of mainframe and optical fiber. The concept of internet technology is often vague: one refers to the host network and the other refers to the software. Information technology itself is just a tool, like a sword or a good pen.
[Edit this paragraph] Confused technical concepts
Data = a record of facts. Last quarter, the sales of series A products in East China was 6.5438+0.2 million. Information = (information) = data+meaning. Last quarter, the sales of A series products in East China decreased by 25% compared with the same period of last year. Intelligence = information+understanding and reasoning. For example, is it because the sales units in East China are not good, or the A series products are in recession, or the overall marketing activities of the company are backward and the competitors are vigorously promoting them? Or other reasons. Knowledge = problem-solving skills. What is the company's strategy to solve this problem? Wisdom = knowledge selection There may be many action plans to deal with, but which wisdom (strategy) to choose. The activity will generate new transaction data.
[Edit this paragraph] The composition of Internet technology
The universal application of Internet technology is a sign of entering the information society. Different people and books have different explanations for this. But basically everyone agrees that it consists of the following three parts:-sensing technology is the extension and expansion of human sensory organs, and the most obvious example is bar code reader; -Communication technology, which is the extension and expansion of human nervous system, undertakes the function of transmitting information; -Computer technology This is the extension and expansion of the function of the human brain, which undertakes the function of processing information. The so-called informatization is to transform other industries and industries with information technology, so as to improve the efficiency of enterprises. In this process, information technology plays the role of a powerful tool. By the way, what is the IT industry? There is a general classification for your reference: internet technology, basic technology, ic research and development, software writing such as INTEL, MS and so on. Internet technology products parts, components, assembly manufacturing such as elite, Volkswagen and so on. ; Internet technology products integrate computer and peripheral manufacturers such as Lenovo and IBM; ; Systematic solutions for Internet technology products and information systems such as Huawei and Hewlett-Packard; Distribution channels and sales of Internet technology products such as Digital China; Internet technology products, services, consulting services and after-sales services such as Blue Express; Public opinion in the Internet technology industry supports IT media such as World Plan Information and CCID; ; Third parties in the Internet technology industry provide various services that need to be matched, such as legal consultation and public relations services; Training Internet technology reserve personnel in various colleges and universities such as computer specialty; Internet technology industry cooperates to organize various associations and gatherings. The whole cycle of integration testing will systematically include software acceptance testing, end-to-end testing, TV picture synthesis testing, system testing, user acceptance testing, multi-motion comprehensive testing and technical drills. Its purpose is to ensure that all IT systems have the required functions and reliability, so as to serve Beijing 2008 Olympic Games smoothly.

[Edit this paragraph] World Internet technology development history
1936 British mathematician A.M. Turing invented the Turing machine, which made theoretical preparations for modern computer hardware and software. 1942, the world's first electronic computer ABC was successfully developed. It has 300 electron tubes, using binary. Its basic architecture is no different from that of modern computers. 1943 British computer "Giant" put into operation. But it was kept secret until 1970. 1945 the father of modern computers: von neumann first put forward the concept of stored program computer, namely "von neumann machine". & ltB& gt； 1946
