Generally speaking, the IT industry is divided into three aspects \ x0d \ x0d \ 1. Network \x0d\2. Software \x0d\3. Integrated circuit \ x0d \ x0d \ If you want to enter the it industry, you must first decide to enter one of these three aspects. \ x0d \ x0d \ Three aspects of employment direction: \ x0d \ x0d \ 1. The direction of integrated circuits, which is a very professional direction, requires job seekers to have strong professional knowledge, which can be supplemented by training, and needs to be well similar to the training of university education; The employment of such talents is very narrow, but if they are employed, the salary will be very high (depending on the situation of the enterprise, of course) \ x0d \ x0d \ 2. The direction of software is wider than that of integrated circuit design. A good software engineer also needs a solid mathematical foundation. Regular training can make a person who has no software foundation become a software blue collar, but it still takes considerable work and study time to become a software designer. Most of these talents are employed by software companies; \x0d\\x0d\3。 Network direction, this aspect is much wider than the first two. Through training, you may gradually become a network engineer from a person who doesn't understand network technology, because network technology is a more operational technology. Employment is also much wider, because informatization is a project of the whole society. Both the government and enterprises are engaged in informatization, and they need to find suitable talents in the network to operate, manage and maintain their own network systems. \ x0d \ x0d \ but all walks of life need different network engineers. \ x0d \ x0d \ What is a network engineer? The post system of enterprise informatization can be used for reference. Enterprises (or governments) need the following four kinds of people in the process of informatization: \ x0d \ x0d \ 1. Director of enterprise informatization: responsible for the goal and scheme decision-making in informatization construction and the direction research in informatization construction; \x0d\2。 Engineering and technical personnel: responsible for the design and construction of information systems, including the construction of equipment, systems, databases and application systems; \x0d\3。 Operation and maintenance personnel: responsible for the operation, maintenance, management and basic development of the information system; \x0d\4。 Operation application personnel: mainly use information systems to do their own work. \ x0d \ x0d \ In the process of enterprise informatization construction and operation, enterprises will outsource the construction process to professional IT companies, so there will be no IT system engineers in general enterprises, so IT can be said that IT system engineers are concentrated in professional IT companies; After the information system is completed, an enterprise will generally have a person or a group to be responsible for the operation, maintenance and management of the information system, which is necessary for the enterprise. Moreover, in terms of cost, the enterprise will recruit someone who knows something about network equipment, network system, database, network management, network security and basic network development to be responsible for its information system. Such people are generally called network managers. This kind of people's knowledge is horizontal and multifaceted, but they are not particularly professional. If an enterprise really encounters a very professional technical problem, IT will generally let the network manager consult a professional IT company with the problem. \ x0d \ x0d \ So from this perspective, the employment of network engineers will be much larger than that of other two types of engineers. \x0d\\x0d\ Now there are many certifications or training certifications called network engineers in society. How do we choose them? We can analyze the network technology system: \ x0d \ x0d \ 1. Network equipment technology mainly involves network hardware construction, including routers, switches, group office networks, wide area networks, etc. \x0d\\x0d\2。 Network operating system mainly involves system management and network management of operating system, and its representative directions are WINDOWS2000, UNIX, LINUX, etc. \x0d\\x0d\3。 Network database, mainly involving databases applied to the network, such as SQL, ORACLE, etc. \ x0d \ x0d \ 4。 Network security, we should not regard network security as the security of operating system and application system. In fact, there are security problems in all aspects of the network, and there is no good and comprehensive certification in China. \x0d\\x0d\5。 Network management involves comprehensive management, optimization, billing, etc. A local area network and a wide area network, and there is no comprehensive certification; \x0d\\x0d\6。 Network application development, basic development and interactive development of enterprise websites, ASP and other technologies. \ x0d \ x0d \ These six aspects are essential factors of enterprise informatization, so if you want to supplement your knowledge, you can do it from these six aspects, and you have to make a positioning, whether to become a comprehensive person or a professional person. However, if you can lay a solid foundation in this respect, it will be more powerful to choose a direction in your work.
