The first point: customer resources are oriented to the whole country, and geographical restrictions are broken through the Internet. The second point: low cost and high income. The training cost is almost the same as the offline training course, but it saves a lot of personnel and site costs. The third point: people who can study in different time periods can study at any time, whether they want to study full-time or in their spare time. Of course, online constraints also have shortcomings: First, the teaching methods are unified, but not all of them are suitable for everyone, and teaching students in accordance with their aptitude is not considered. The second point: without a physical training and learning classroom, it is difficult to get everyone's approval. The first point: whenever and wherever, you can learn through pc or mobile devices, and the learning progress can be controlled more according to your actual situation. The second point: you don't have to study full-time, you can take care of both work and study. On the basis of convenience, it also has its own shortcomings: the most important point is the long study time. Generally, it takes four to six months to complete the learning objectives through offline training courses, while online learning takes longer. Secondly, the problems encountered in the learning process cannot be solved in time. Most importantly, it is impossible for teachers to take care of everyone's learning progress, and it is impossible to tell all students some key problems in different ways. Generally speaking, participating in online training requires students' self-discipline. At the same time, it is difficult to solve the problem in time, and it often takes a lot of time to consult the information. In addition, students can watch and learn online anytime and anywhere, regardless of time limit, while offline software training courses can only be studied at a fixed time and place.
