Internet technology refers to information technology developed and established on the basis of computer technology. Internet technology connects different devices through the wide area network of computer network, which speeds up the transmission of information and broadens the access channels of information, promotes the development of various software applications and changes people's life and learning methods. The universal application of Internet technology is a sign of entering the information society.
Application 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 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 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.
Conceptual integration test, also known as assembly test or joint test, is based on unit test, and all software units are assembled into modules according to the requirements of the outline design specification.
Whether the work of each part in the process of subsystem or system meets or realizes the corresponding technical indicators and requirements. Practice shows that although some modules can work independently, they cannot be guaranteed to work normally when they are connected.
