Android
Android is a popular mobile operating system developed by Google. It is based on the Linux kernel and is designed for touchscreen mobile devices such as smartphones and tablets. Android is known for its user-friendly interface, vast app ecosystem, and customizability.
History of Android:
Android was initially developed by a startup company named Android Inc. in 2003. Google acquired Android Inc. in 2005 and announced the first Android-powered smartphone, the HTC Dream, in 2008. Since then, Android has grown to become the most widely used mobile operating system in the world.
Features of Android:
User Interface:
Android is a popular mobile operating system that is used by millions of people around the world. The user interface in Android refers to the way that users interact with the system through the screen of their device.

Multitasking:
Multitasking on Android refers to the ability of the operating system to run multiple apps simultaneously, allowing the user to switch between them seamlessly. Android's multitasking capabilities allow users to perform multiple tasks at once, such as browsing the web while listening to music, or checking email while writing a document.
Android uses a feature called "task switching" to manage multitasking. When you launch an app, Android creates a new task for that app, which includes all the activities that belong to that app. Activities are individual screens or windows within the app.
When you switch from one app to another, Android pauses the first app's task and starts the second app's task. The paused task is kept in memory, so when you switch back to the first app, it can quickly resume where it left off.
In addition to task switching, Android also supports split-screen multitasking, where two apps can be displayed side-by-side on the screen. This feature is particularly useful on larger-screen devices like tablets.
Overall, Android's multitasking capabilities allow users to be more productive and efficient by enabling them to perform multiple tasks at once without having to constantly switch between apps.
Google Assistant:
Google Assistant is an artificial intelligence-powered virtual assistant developed by Google that is available on Android devices. It is designed to provide users with a more conversational and personalized way of interacting with their mobile devices.
