Mobile Operating System
A mobile operating system (OS) is software that manages hardware and software resources on mobile devices such as smartphones, tablets, and wearables. It provides core functionalities like user interface, app execution, memory management, and connectivity, enabling users to run applications and interact with their devices. Popular examples include Android, iOS, and HarmonyOS.
Developers should learn mobile operating systems to build native or cross-platform apps for billions of users worldwide, as they are essential for targeting specific device ecosystems like Android or iOS. This skill is crucial for roles in mobile app development, IoT, and embedded systems, where understanding OS-level features (e.g., permissions, notifications, battery optimization) improves app performance and user experience.
