Important majors in IT industry include computer information engineering, communication engineering and computer network engineering. Electronic industry is dominated by electronic hardware, supplemented by software, and IT industry is dominated by software, supplemented by hardware.
It is the abbreviation of information technology, which means "information technology", including modern computer, network, communication and other information fields. The wide application of information technology is a sign of entering the information society. For example, those who engage in internet and online games, such as those who engage in software, are all in the IT industry. Different people and books have different explanations for this. But basically everyone agrees that it consists of the following three parts:
sensing technology
This is the extension and expansion of human sensory organs, the most obvious example is bar code reader;
communication technology
This is the extension and expansion of human nervous system, which undertakes the function of transmitting information;
Computer technology This is the extension and expansion of human brain function, and it 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. There is a general classification of IT industry. For your reference: the provision of IT basic technology, IC R&D, software compilation, IT productization components, components, assembly and manufacturing, IT product integration such as elites and the public, computer and peripheral manufacturers such as Lenovo, IBM IT product systematic solutions, information systems such as Huawei and HP IT product distribution channels, sales such as digital China IT product service consulting services and after-sales services such as Blue Express, and IT industry public opinion supports IT media such as CCW and CCID IT industry third-party services.
Various supporting services, such as legal consultation, public relations service, IT reserve personnel training, various colleges and universities, such as computer majors, IT industry cooperation organizations, various associations and parties, are generally electronic products. For example, computers, mobile phones, projectors, printers, and all computer peripherals are called IT products. IT industry refers to the industry that manages these products, including network and software, and is called IT industry. In short, it covers a wide range of contents.
IT talents are practitioners in these industries. The IT industry (usually computer industry) happens to have these two completely different faces: one is the beauty of high technology; A pair of greedy, naked profit in the mall. It combines human intelligence, enterprising spirit and the dream of getting rich by hook or by crook, contributing to the most spectacular explosion of new technologies since the19th century. IT talents refer to those who are engaged in information technology (IT) and have a solid IT theory and practical technology.
It actually has three levels:
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).
In fact, it also includes Internet applications. Some people understand that it 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.
