This presentation discusses mobile operating systems. It defines a mobile operating system as the software platform that controls functions and features on mobile devices, similar to how desktop OS's work. It then covers several major mobile OS's including: Java ME, Symbian OS, Linux, Windows Mobile, iPhone OS, Palm OS, and Android. For each it provides a brief overview of its origins, features, and development platforms. It concludes that in 2013, Android from Google had the largest worldwide mobile device market share at 78.4%, followed by Apple's iOS at 8.16%, and Microsoft's Windows Mobile at 3.2%.

3. An operating system (OS) is an interface between
hardware and user, It manages the hardware and
software resources of the system.
The operating system that controls mobile device is called
Mobile OS. They are simple and deal with the wireless
versions of broadband and local connectivity, mobile
