Android is an open-source, Linux-based operating system designed primarily for mobile devices such as smartphones and tablets. It was developed by Google in 2005 and has since become the most popular mobile operating system in the world.
Android is built on the Linux kernel and includes a user interface, middleware, and application framework. The user interface is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching. The middleware provides a set of fundamental system services, such as security, memory management, and process management. The application framework enables developers to create applications using high-level APIs in Java, C++, or Kotlin.
Android applications are distributed through the Google Play Store or third-party app stores. The Play Store has more than 3 million apps, ranging from games and social media apps to productivity and business tools.
Android is known for its high level of customization, allowing users to personalize their devices with widgets, themes, and launchers. It also supports multiple user accounts and offers a wide range of accessibility features, making it accessible to users with disabilities. Overall, Android is a versatile and powerful platform that has revolutionized the way people interact with mobile devices.
