What operating system does the Android system belong to?

Android is an open-source operating system based on the Linux kernel, developed by Google and the Open Handset Alliance. Originally designed for mobile devices like smartphones and tablets, it has since expanded to other areas such as smart TVs, automotive embedded systems, and more.

Android is structured with multiple layers, including the Linux kernel, hardware abstraction layer, runtime library, application framework, and application components. The Linux kernel provides low-level hardware drivers and system scheduling functions, while the hardware abstraction layer offers a unified interface for different hardware devices. The runtime library manages the application’s runtime environment, including memory management, thread management, and security. The application framework provides various APIs and tools to help developers create different types of applications more easily. The application layer is the interface where users directly interact with the system, including various applications and user interfaces.

The open nature of Android allows developers to freely customize and modify the system, adding various functionalities and features. Additionally, Android also supports the downloading and installation of various applications, allowing users to obtain and update applications through the Google Play Store or other channels.

In conclusion, Android is an open-source operating system based on the Linux kernel, known for its strong customization capabilities and rich app ecosystem.
