Project management division, an information system with domestic first-class, second-class, third-class and fourth-class computer certificates, system analyst, software designer, network engineer, multimedia application designer, embedded system designer, information system supervisor, programmer, network administrator, e-commerce technician and information processing technician.

Embedded system refers to a special computer system used to perform independent functions. It consists of a series of microelectronic chips and devices, including microprocessors, timers, microcontrollers, memories, sensors and so on. And micro-operating system and control application software embedded in memory, which can realize various automatic processing tasks such as real-time control, monitoring, management, mobile computing and data processing. Embedded system is application-centered, based on microelectronic technology, control technology, computer technology and communication technology, and emphasizes the coordination and integration of hardware and software. Software and hardware can be customized to meet the requirements of the system for function, cost, volume and power consumption.

The simplest embedded system only has the control ability to perform a single function, such as the application of single chip microcomputer. The only ROM has only a single function control program, and there is no micro-operating system. Complex embedded systems, such as Personal Digital Assistant (PDA) and Pocket PC (HPC), have almost the same functions as personal computers. Essentially, it is different from PC in that micro-operating system and application software are embedded in rom, RAM and/or flash memory, instead of being stored in carriers such as disks. Many complex embedded systems are composed of several small embedded systems.
