Mobile Computing: Operating Systems Chandan Shrivastava (Student) Department of Computer Science & IT, JRNRVU, Udaipur. cvkshri@gmail.com Abstract:- Different types Operating System of mobile we talked and they are investigated in details. Then, existing operation systems that are most popular for mentioned devices are talked. Keyword: Android, Symbian, iOS. Introduction A mobile operating system, also called a mobile OS, is an operating system that is specifically designed to run on mobile devices such as mobile phones, smartphones, PDAs, tablet computers and other handheld devices. The mobile operating system is the software platform on top of which other programs, called application programs, can run on mobile devices. Mobile devices with mobile communications capabilities (e.g. smartphones) contain two mobile operating systems - the main user-facing software platform is supplemented by a second low-level proprietary real-time operating system which operates the radio and other hardware. Research has shown that these low-level systems may contain a range of security vulnerabilities permitting malicious base stations to gain high levels of control over the mobile device. Android Android powers hundreds of millions of mobile devices in more than 190 countries around the world. It's the largest installed base of any mobile platform and growing fast—every day another million user’s power up their Android devices for the first time and start looking for apps, games, and other digital content. Android gives you a world-class platform for creating apps and games for Android users everywhere, as well as an open marketplace for distributing to them instantly.

The underlying OS was historically created by Symbian Ltd and licensed by Nokia and other phone manufacturers, who layered UI platforms over the top (Nokia S60, NTT DoCoMo's MOAP and UIQ Technology. In late 2008 Nokia purchased Symbian Ltd, and created the (independent) Symbian Foundation to open source and manage the software.

iOS iOS from Apple finished second in the race in 2013. Apple is known for its innovative products and quality mobile applications. iOS operating system had been the favorite of people that love quality. Although there are quite a number of free mobile apps in the Apple’s app store, the cost of iDevices is one of the major reasons that pushed the operating system to the second place
