Which of the following is a common operating system for mobile devices?

Android is a widely recognized operating system specifically designed for mobile devices such as smartphones and tablets. Its architecture is based on the Linux kernel, which provides a robust and flexible framework for application development and system operation. Android's open-source nature allows for extensive customization by manufacturers and developers, making it incredibly versatile and adaptable for a broad range of mobile hardware.

This operating system has gained popularity due to its user-friendly interface, extensive app ecosystem available through the Google Play Store, and support for various hardware configurations. It is particularly optimized for touchscreen interactions, which are prevalent in mobile devices, ensuring a seamless user experience.

Other options like Linux, Windows, and macOS are primarily designed for desktop or laptop computers. While Linux can be adapted for mobile devices, it is not typically classified as a common mobile operating system in the same way Android is. Windows has made attempts to penetrate the mobile market, but its usage is significantly lower in that space compared to Android. macOS, on the other hand, is exclusive to Apple's desktop and laptop computers and does not operate on mobile devices, although Apple's iOS is the operating system designed for their mobile devices.
