What are the majors in IT?

The IT industry is generally divided into three aspects\x0d\\x0d\1. Network\x0d\2. Software\x0d\3. Integrated circuit\x0d\\x0d\If you want to enter IT industry, then you must first decide to enter one of these three areas. \x0d\\x0d\Three aspects of employment direction:\x0d\\x0d\1. Integrated circuit direction, this is a very professional direction, requiring job seekers to have strong professional knowledge, which can be easily trained To supplement, they need good training similar to university education; the employment opportunities of this kind of talents are very narrow, but if they are employed, their salary will be very high (of course it depends on the situation of the company)\x0d\\x0d\2. Software direction, This aspect is relatively more professional than integrated circuit design. A good software engineer also needs to have a solid mathematical foundation. Regular training can make a person with no software foundation become a software blue-collar worker, but to become a software designer, it still requires considerable work and study time; most of these talents are employed in software companies; \x0d\\x0d\3. Network Direction, this aspect covers a much wider area than the first two. Through training, it is possible to gradually become a network engineer from a person who does not understand network technology, because network technology is a technology that is more oriented towards operations. The employment scope is also much wider, because informatization is a project of the whole society. Governments and enterprises are all carrying out informatization, and they all need to find suitable talents in the network to operate, manage and maintain their network systems. \x0d\\x0d\ Different network engineers are needed by all walks of life. \x0d\\x0d\What is a network engineer? We can gain some understanding from the position system of enterprise informationization. The following four types of people are needed in the process of enterprise (or government) informatization:\x0d\\x0d\1. Enterprise informatization manager: responsible for the goals and program decisions in informatization construction, and 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 information systems ;\x0d\4. Operation and application personnel: mainly use information systems to perform their jobs. \x0d\\x0d\From the perspective of the process of enterprise information construction and operation, an enterprise will outsource the construction process to a professional IT company to complete, so generally an enterprise will not have IT system engineering and technical personnel. It is said that IT system engineering and technical personnel are concentrated in professional IT companies; and when the information system is built, the enterprise will usually have one person or a group responsible for the operation, maintenance, and management of the information system. These people are the company's It is a must, and from a cost perspective, the company will recruit someone who has knowledge of network equipment, network systems, databases, network management, network security and basic network development to be responsible for its information system. This type of person generally Call the network administrator. The knowledge of such people is horizontal and multi-faceted, but not particularly professional. If an enterprise really encounters a very professional technical problem, it will usually ask the network manager to consult a professional IT company with the problem. \x0d\\x0d\So from this perspective, the employment opportunities of network engineers will be much greater than those of the other two types of engineers.

\x0d\\x0d\There are many certification trainings or training certifications called network engineers in society now. How do we choose? We can analyze and understand the network technology system: \x0d\\x0d\1. Network equipment Technology, which mainly involves the hardware construction of the network, including routers, switches, local networks, and broadband networks. Representatives in this area are CISCO and NORTEL; \x0d\\x0d\2. Network operating system, which mainly involves the operating system System management and network management, the representative ones in this direction are WINDOWS2000, UNIX, LINUX, etc.; \x0d\\x0d\3. Network database, which mainly involves databases used in the network, the representative ones in this direction are SQL and ORACLE, etc.;\x0d\\x0d\4. Network security. We should not think of network security as the security of operating systems and application systems. In fact, security issues exist in all aspects of the network. In this regard, there is no such thing in China. There is a better and more comprehensive certification;\x0d\\x0d\5. Network management, which involves comprehensive management, optimization, billing, etc. of a local network and wide network, and there is no comprehensive certification;\x0d\ \x0d\6. Network application development, basic development and interactive development of corporate websites, technologies include ASP and so on. \x0d\\x0d\These six aspects are essential factors for enterprise informatization, so if you want to supplement your knowledge, you can supplement it from these six aspects. You must also position yourself to become a comprehensive personnel, or professional personnel. However, if you can lay a solid foundation in this aspect, then you will be even more powerful when you choose a direction in your work.
