At present, the electronic commerce and the customer alliance network shopping and network analysis is becoming increasingly popular, mainly is the result of highly developed and popular wireless communication. The work of software mainly includes artificial intelligence and the Internet of things, and the knowledge of artificial intelligence will be used in the research of the Internet of things. Assembly language mainly includes sequential branch cycle programming, subroutine definition and call. The core component of microcomputers is microprocessors. Intel introduces Pentium MMX (multi energy Pentium), Pentium Pro (high energy Pentium), Pentium two generation, three generation, four generation and so on. And Itanium. IBM is also known as the blue giant. The IBM PC series microcomputer has the characteristics of advanced design, rich software, complete functions, cheap price and openness. The system function call mainly includes two kinds of DOS and BIOS. In the DOS operating system, there are two layers of internal subroutines for users to use, and they are the basic input-output subroutines, BIOS and DOS layer function modules. Many functions of DOS are similar to those of BIOS calls. They both have similar writing formats, but DOS provides more necessary tests. Therefore, DOS operation is generally easier than the corresponding BIOS part. Assembly language mainly involves BCD code and ASCII code. Software engineering mainly involves the use of visio_project_powerdesign mapping, library management system feasibility study report and project development plan writing, data flow diagram and system flow chart production. Project 2003 project management and Gantt chart. "Ticket booking system" is an important issue in the field of software engineering. The UML modeling under software engineering is modeled with Visio, powerdesign, and rationalrose. The aerospace science and technology industry is also an important application of the Internet of things.
