Personally, I think there are two kinds of development, for example:

Software system development, information system development, application software system development, etc., this kind of development is to write code. Software system refers to the computer software system composed of system software, support software and application software, it is the part of the computer system composed of software. Operating system is a kind of system software that manages hardware and software resources, controls program execution, improves human-computer interface, rationally organizes computer workflow and provides a good operating environment for users to use computers. Operating system is located above the hardware layer, all the software layer below an essential, the most basic and most important kind of system software. It provides unified control, scheduling and management of all software, hardware and data resources of a computer system. As Huixin Cloud, a platform for professional system development software customization.

Hardware system development, hardware system, refers to the physical equipment that constitutes the computer, that is, the mechanical, optical, electrical, magnetic devices composed of physical components with computing, control, storage, input and output functions. Such as CPU, memory, floppy disk drives, hard disk drives, CD-ROM drives, motherboards, a variety of cards and the entire machine in the host, monitor, printer, plotter, modem, etc., the entire hardware is also referred to as "hard equipment".

With the complexity of electronic systems, system design has become an important discipline, the traditional repeated testing method has become increasingly unsuitable for the development of the times. The rapid development of hardware and software co-design technology is more and more attention. It is under the guidance of the system target requirements, through a comprehensive analysis of the system hardware and software functions and existing resources, maximize the concurrency between the system hardware and software, coordinate the design of hardware and software architecture, so as to make the system work in the best working state. Also known as intelligent hardware, intelligent hardware is a technological concept that refers to the intelligent transformation of traditional equipment by combining hardware and software.

This answer is referenced in the online information, Huixin Cloud, professional software collaborative industry ecosystem platform web link, can realize IT software online research and development, software online trading, IT software supply chain services, to solve the software engineering design, software development, software testing and other needs.

Answer if there is insufficient, light spray, thank you for adopting!
