Android OS - Operating System

Android OS (Operating System) is a Linux-based OS developed by the Open Handset Alliance. It is designed primarily for touch screen mobile devices such as smart phones and tablet computers.

The Android OS was originally invented by Android, Inc. that was bought by Google in 2005. Google teamed up with other companies to form the Open Handset Alliance which had become responsible for the continued development of the Android OS.

Each time the 
Open Handset Alliance releases an Android version, it names the release after a dessert. Android 1.5 is known as Cupcake, 1.6 as Donut, 2.0/2.1 as Eclair, 2.2 as Froyo and 2.3 is dubbed Gingerbread. Once a version is released, so is its source code.

in October 2016, Google introduced the Pixel and Pixel XL smartphones marketed as being the first phones made by Google and exclusively featured certain software features. The Pixel phones replaced the Nexus series with a new generation of Pixel phones launched in October 2017.

The Android OS is designed for phones. It has many features including integrated browser, based on the open source Web Kit engine, optimized 2D and 3D graphics, multimedia and GSM connectivity, Bluetooth, EDGE, 3G, Wi-Fi, Sq Lite, Camera, GPS, Compass, and accelero-meter.
