Google is a global technology company focused on providing Internet based products and services. Android and Chrome OS are two major operating systems created by Google, both of which are open source, and are based on the Linux kernel. Android is designed for mobile devices, while Chrome OS is designed for personal computers. In the case of popularity, Android is used by billions of people around the world, while Chrome OS is preinstalled with the Chromebook, so it is not so popular as Android. There are some other Google developed operating systems, but Android is the only one that is widely installed on a large number of computing devices.
