To begin with, an Operating system (OS) is computer software that supports basic functions of a computer and manages computer hardware by providing services for the Computer Programs. Mobile Operating System is the one which Operates on Mobile devices such as Smartphones, Tablets and Other PDAs.

Before we get to know what an Android Operating System is, let us know what OHA is.

Open Handset Alliance (OHA) is a consortium formed by Google in 2007 to develop Open standards for the mobile devices. The consortium has 84 firms approximately (as of 9th Aug 2013) such as Google,Sony,Dell,Samsung, Lg,HTC etc.,The license is based on Open Source and OHA members should only manufacture mobiles which are compatible with Android OS. Some of the major competitors include Apple, Microsoft, Blackberry, HTC etc., HTC is listed in OHA list and the competitors list as well because HTC manufactures mobiles for Android Platform and other platform as well like, Windows mobile.


Android means Human Robot or a robot with Human Appearance. It’s a Linux based (Open Source) Operating System and the earlier intention was to develop OS for Digital Cameras. It was found by Andy Rubin, Rich Miner, Nick Sears and Chris White in October 2003 at California. Android was acquired by Google on 17th August 2005. Key employees of Android including Rubin, Miner and White stayed at the company after acquisition. Till March 2013, Android was led by Andy Rubin and then he was replaced by Sundar Pichai.
