definition of internet Technology

internet technology refers to a kind of Information Technology (IT for short) developed and established on the basis of computer technology. The second layer refers to software, including all kinds of software that can be used to collect, store, retrieve, analyze, apply and evaluate information. It includes commercial management software such as ERP (enterprise resource planning), CRM (customer relationship management) and SCM (supply chain management), 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 various 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 quality of analysis and assist decision-makers to make decisions (to emphasize one point, it only assists rather than replaces people's decision-making). 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 the front hard and the back soft. Usually, the third layer has not been paid enough attention, but in fact, IT is only when information is effectively applied that the value of IT can be fully exerted and the goal of informatization can be truly realized. Informatization itself is not a goal, it is just 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 steam engine, railway, telegraph and telephone, electric power and other infrastructure construction, Moore's law is also used to prove the development of mainframe and optical fiber. The concept of internet technology is often ambiguous: it refers to the host network for a while and software for a while. Information technology itself is just a tool, just like a sword or a good pen.

[ Edit this paragraph] Technical concept that is easy to be confused

Data = record of facts. In the last quarter, the sales of A series products in East China were 1.2 million. Information = (information) = data+meaning. In the last quarter, the sales of A series products in East China decreased by 25% compared with the same period 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 have entered a recession, or the overall marketing activities of the company are backward, which is caused by the strong promotion of competitors? Or other reasons. Knowledge = problem-solving skill. 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. Actions will generate new transaction data.

[ Edit this paragraph] Composition of Internet technology

The widespread 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, which is the extension and expansion of human sensory organs, and the most obvious example is bar code reader; -Communication technology This is the extension and expansion of the human nervous system, which undertakes the function of transmitting information; -Computer technology This is the extension and expansion of human brain function, which undertakes the function of processing information. The so-called informatization is to transform other industries and trades with information technology, so as to improve the efficiency of enterprises. In this process, information technology has assumed the role of a powerful tool. By the way, what is IT industry? There is a general classification for your reference: Internet technology, basic technology, IC research and development, software writing such as INTEL, MS, etc. Internet technology products components, components, assembly manufacturing such as elite, Volkswagen, etc.; Internet technology products integrated computer and peripheral manufacturers such as Lenovo and IBM；; Systematic solutions for Internet technology products and information systems such as Huawei and HP; Internet technology products distribution channels and sales such as Digital China; Internet technology products, services, consulting services and after-sales services such as Blue Express; Internet technology industry public opinion supports IT media such as CCW and CCID；; The third party in the Internet technology industry provides various services that need to be matched, such as legal consultation and PR services; Internet technology reserve personnel train 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-sports 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 2118 Olympic Games smoothly.

[ Edit this paragraph] World Internet Technology Development History

In 1936, British mathematician A.M.Turing invented Turing, which made theoretical preparations for modern computer hardware and software. In 1942, the world's first electronic computer ABC was successfully developed. It has 311 electron tubes and adopts binary system. Its basic architecture is no different from that of modern computers. In 1943, British computer "Giant" was put into operation. But it was kept secret until 1971. In 1945, the father of modern computer: von Neumann first put forward the concept of stored program computer, that is, "von Neumann machine". < B> 1946 <; /B> On February 11, the electronic digital integrator and computer were born. It is equipped with 18,111 vacuum tubes, with a total weight of 31 tons and a cost of nearly 511,111 US dollars. It is the world's first multifunctional, all-electronic digital computer, which can realize thousands of multiplication operations per minute. < B> 1946 <; /B> In May, Cambridge University in England successfully developed the first von Neumann machine EDSAC.

In 1969, Bell Laboratories developed the first multi-task and multi-user computer time-sharing system Unix with assembly language. IBM established the software market by allowing customers to purchase its software and hardware separately. The U.S. Department of Defense began to study ARPANET, which is regarded as the beginning of the Internet. In 1971, Ken Thompson and Dennis M.Ritchie of bell laboratory began to develop Unix operating system. Optical fiber with transmission loss of only 21 dB/km and semiconductor laser which can work continuously at room temperature have been successfully developed, and optical fiber communication is becoming practical.
