Edge Computing in Mobile Information System for Digital Construction of College English Teaching

As an education mode and teaching method of modern education, digital teaching in colleges and universities plays a role of bridge and hub in the development of modern education. Digital teaching has become one of the important driving forces for the development of digital and informatization of education in colleges and universities. This paper combines edge computing and digital technology to study the mobile information system used in the digital teaching of college English, namely, the digital teaching platform. In the technical part, this article clarifies the concept of mobile information system and introduces edge computing, cloud computing, digital system structure, and other technologies in detail; the system design and implementation part introduces the system architecture, function design, and how to realize the system function. In the system test section, black box and white box tests were performed on the system. The test results show that all functions of the system can be used normally and have certain feasibility. The mobile information system reduces the average content transmission delay (ADL) by approximately 14%-22% and 21%-31%, respectively, which greatly improves the efficiency of digital teaching of English in colleges and universities.
