operating system with the Linux kernel for mobile devices such as mobile phones, smartphones, tablets (tablet PCs) and netbooks.
In 2013, it was the most popular mobile system in the world. These kernels and some other components that have been adapted for Android are published under the GNU GPL license. Android, however, does not contain code from the GNU project. This feature distinguishes Android from many other existing Linux distributions. Android is built on the ARM, MIPS, x86 , x86-64 architecture and on a monolithic kernel. In 2019, the latest version is 10. Initially it was developed by Android Inc. (bought later by Google), then passed under the wings of
the Open Handset Alliance.
