The computer's operating system is one of the most important "components" of computers. Almost all kinds of computers, including mobile phones, video game systems, e-book readers, and DVR, require an operating system to function properly. When the computer turns on, the operating system controls system resources such as processor, memory, disk capacity, and instructs the computer to process. The operating system allows the user to work on the computer without knowing details about the operation of the hardware.

For desktops, laptops, smartphones and video game systems, modern computers require an operating system. This is the core software on the computer that is located between the application software and the hardware, performs memory and computing resource allocation, file management, and application security rules implementation. The operating system defines how files are stored by the computer, how to switch between various applications, how to manage the memory, how to secure the security, and how to interact with peripheral devices such as printers and cameras. Different operating systems are different ways to solve all these problems. As a result, normally you can not run Windows programs on Macintosh computers, and the permissions on Android phones are different from iPhone's permissions.

Imagine a computer vision technology that uses a camera to track the miners' staff. As this system relies on cameras that capture video and photos, it reduces the need to hire a supervisor to oversee mining operations. Imagine improving the performance of miners' projects by performing labor productivity analysis and safety monitoring. Imagine software can judge whether workers' activities are safe or productive. Imagine automatically monitoring people's trajectory for safety, safety and process analysis.

Imagine that you are a personal robot shopping in London, not a game, sitting at your computer at home and walking around the market and shopping districts, except to sit comfortably in New York. Please imagine that you can help the disaster site, clean up the debris on the highway in a few seconds, and provide rescue activities to the elderly.
