The microcomputer hardware system consists of two parts, namely the host computer and external devices.

Let’s briefly introduce the hardware system:

The hardware system refers to the physical equipment that constitutes the computer, that is, it is composed of mechanical, optical, electrical, and magnetic devices that have the functions of computing, control, storage, Physical components for input and output functions. Such as CPU, memory, floppy disk drive, hard disk drive, optical disk drive, motherboard, various cards and the host computer, monitor, printer, plotter, modem, etc. in the complete machine. The complete machine hardware is also called "hard device".

With the complexity of electronic systems, system design has become an important discipline, and the traditional trial and error method has become increasingly inappropriate for the development of the times. The rapidly developing software and hardware co-design technology has attracted more and more attention. It is guided by the system target requirements, through comprehensive analysis of the system software and hardware functions and existing resources, to maximize the concurrency between the system software and hardware, and to coordinate the design of the software and hardware architecture so that the system can work at its best state.
