Android is an open-source operating system used for mobile devices like smartphones and tablets. It is based on the Linux kernel and allows developers to create over 1.3 million apps. Android devices use wireless technologies like 3G, 4G, WiFi and Bluetooth. While initially developed for phones, Android now powers many other devices including cars, TVs, microwaves and more. New versions of Android are continually released with improvements to the user interface, additional features and compatibility with newer technologies. However, Android also faces limitations such as attracting hackers due to its open source code and high battery usage compared to other mobile operating systems.
