1, talent demand. With the development of Internet. The shortage of IT talents will become more and more serious. According to conservative estimates, the demand for IT talents in China market currently exceeds 200,000 every year. However, the current IT education in China is mainly the academic education of computer, electronics, telecommunications, information technology and other related majors in colleges and universities, and the number of college graduates trained every year is about 50,000, which is far from meeting the market demand. The extreme shortage of IT technicians forces many companies to offer high salaries to hire qualified professionals, and the generous treatment of these positions attracts many non-IT personnel. So many people try to get these positions through various trainings.

2. Job requirements. Good employment prospects and salary in IT industry attract a large number of non-computer majors, mostly young people. They urgently need to rely on learning and training to gain the technical ability to enter the IT industry. On the other hand, career changes and replacement in IT industry are also the most frequent, which requires practitioners to keep learning to keep this continuous working state. At the same time, the more advanced the technology a person learns and the more comprehensive the technology he has, the broader his career development prospects and the greater his chances of choosing a job. In addition, due to the rapid development of Internet technology, many people who have mastered outdated technology have to receive retraining to keep up with the latest technology. With the continuous development of China's economy and the improvement of informatization level, the proportion of enterprises' investment in informatization has gradually increased, so employees are required to learn to operate microcomputers.
