1. Electronic Science and Technology mainly studies the basic knowledge and skills in the fields of microelectronics, optoelectronics and integrated circuits, and carries out the design, manufacture and scientific and technological development of various electronic materials, components, integrated circuits, electronic systems and optoelectronic subsystems. For example, the development of microelectronic technology used in GPS, cable TV and weather forecast, the design and manufacture of some microelectronic devices in game machines and computers, and the development and application of microprocessors such as automobile anti-theft system and taxi meter.

2. Information engineering mainly studies the basic knowledge and skills of information collection, transmission, processing, utilization, analysis and control system design, and carries out the design and debugging of communication network and network security foundation, information collection and processing, etc. For example: the design of face and fingerprint information acquisition system, the design of medical CT tomography scanner, etc. Compared with communication engineering, information engineering is more inclined to information collection, and communication engineering is more inclined to information transmission.
