In classroom teaching, when students want to learn high-end servers and the server-client based network, they must have enough space and computer equipment to control multiple computers and meet the needs of the course. During the MCO, to allow students to study high-end server and network-connected homework at home, SBIT adopted a powerful "Virtual Lab" created by an international technology certification body to help trainers teach online virtual practicals. Allow students to master and complete high-end server and online homework in online virtual practical. Therefore, during the MCO, the student's academic progress has not been significantly affected. The students can graduate successfully after mastering and practicing the technical skills required by the market within the course duration.
