Today, any company, agency, or organization must have a computer network to work. Therefore, each organization needs to have personnel to administer the computer network system. In Vietnam, a large-scale information technology application enterprise such as a bank, insurance company, airline, e-commerce, etc. needs to have a network administration department with a staff of several tens or even hundreds of people. , medium enterprises need about 4-5 people. Small businesses also need at least one person in charge of the network.
Due to the explosive development of the information technology industry and the high demand of businesses, the number of personnel studying the network industry is quite large. The peculiarity of the information technology industry is that new technologies change at a rapid pace, and the computer network industry is no exception. In recent years, the number of students studying this major is very large, but to follow this major to the end is not something that every student can do.
