Integrated circuits (or chips) are designed according to their uses and functions, and belong to the field of microelectronics. Integrated systems: Does this refer to system integration? If so, to achieve some industrial or service purpose, a large number of sensors, computing, amplification and other chips, actuators are integrated into a system. It is hardware engineering (of course, software gives it life).
Electronic information engineering: it is more extensive, but mainly refers to the processing and transmission of information, which is hardware system integration and software support.
