[2] Some of the current features and specifications of android Every phone requires some type of operating system to run its are: services. The operating system is responsible for determining the functions and features available on your device. The acceptance of a third party application, so called mobile apps is also based on the mobile operating system. Every manufacturer will have chosen the operating system for that specific device. In order to know the device compatibility and support for the mobile applications, its necessary to learn about the mobile operating system. This paper gives an idea about different mobile operating systems and also a comparative study on mobile operating systems.

Introduction Smartphone has increased its usage from mere communication device to a software intensive device like PCs to perform all kind of applications. This change is due to the development of innovative mobile operating systems and the unique characteristics of smart phones. Smart phones are small and handy with multiple, frequent and continuous connectivity to their own applications. The operating system manages the hardware and software resources in the device and performs various tasks. The mobile OS can be Fig. 1: Current Features of Android The Android NDK application differentiated based on the existing PC platforms such as Real looks as follows: time operating system, single user single tasking operating system, single user multi tasking operating system and multi user operating system. These platforms are based on the number of user and the number of applications running on the device. This paper discusses about various mobile operating systems. II. Major Operating System A. Android Android is a linux based operating system developed by google/ open handset alliance. It is a free and open source operating system that supports ARM, MIPS, x86 architecture which is programmed in C, C++ and java.[8] Android's releases are nicknamed after sweets or dessert items like Cupcake (1.5), Donut (1.6), Eclair (2.0), Frozen Yogurt ("Froyo") (2.2), Ginger Bread (2.3), Honeycomb (3.0), Ice Cream Sandwich (4.0), Jelly Bean (4.1), (4.2), (4.3) and Kit Kat (4.4) [1].

Symbian Symbian is a descendant of Symbian OS which was developed by Symbian Foundation.Symbian 3 is the latest version was used in Nokia N8.The primary programming language is C++. It includes Fig. 3: Features of iOS features like • 2D and 3D graphics acceleration D. Blackberry OS • Touch-based interaction Blackberry OS is a QNX(Unix-like) based operating system • UI widgets developed by Blackberry Ltd.. It is a proprietary OS that supports ARM CPU architecture which isprogrammed in C, C++(native, H. Palm OS and Web OS cascade SDK, HTML5, javascript, CSS and java [8]. Palm OS was developed by Palm and later acquired by Hewlett Features include: Packard. Palm Os is a combination of phone and palm pilot PDA. • Bluetooth sharing with Android runtime It is a linux based OS. • Multi-touch interface WebOS was developed to replace palm OS. WebOS also known • Dual-layered virtual keyboard as LG webOS webOS or HP webOS, is a Linux kernel based operating system for smart TVs, formerly a mobile operating F. Windows Phone system initially ran on Palm Pre and Palm Pixi. The webOS mobile Windows phone is a windows CE 7/windows NT 8 based operating platform introduced features so innovative that some are still in system developed by Microsoft. It is a proprietary OS that supports use by Apple, Microsoft and Chrome [12]. ARM architecture which is programmed in XNA (.NET C#), VB.NET, silverlight, native C/C++, winRTP(XMLA) and DirectX.

Other Operating Systems F. Sailfish OS Sailfish is based on linux operating system developed by sailfish alliance and written by jolla. It is a free and open source operating system except proprietary components that supports ARM, x86, x64. The primary programming language is C++ and QML. Android application can directly run on sailfish OS. It can also support software from platforms like MeeGo, HTML5, Unix and Linux. G. LiMo LiMo is a Linux based operating system for handheld devices. It is developed by LiMo Foundation. It has modular plug-in architecture, and supports DRM. LiMo application developers use SDKs to write managed code running in a JVM, browser apps for WebKit, and native code. Fig. 4: Relationship Between Different Operating Systems H. Bada A. Maemo Bada OS is developed by Samsung electronics. The term bada Maemo Maemo is a linux based operating system developed meaning “ocean” or “sea” in Korean. This is a platform with by Nokia and handed over to Hildon foundation. The Maemo a kernel configurable architecture, which allows using either a operating system is designed for Tablets, which feature very similar proprietary real-time operating system hybrid (RTOS) kernel or specifications to Nokia's high series and E-series cellphones. the Linux kernel. Native applications are developed in C++ with Maemo 5, also known as Fremantle, is the default operating system the Bada SDK, and the Eclipse based integrated development on the Nokia N900. The release features a much more finger- environment (IDE). GNU-based tool chains are used for building friendly and consistent user interface, and an X-server based on and debugging applications. The IDE also contains UI Builder, Xorg rather than KDrive [13]. with which developers can easily design the interface of their applications by dragging and dropping UI controls into forms. B. Moblin For testing and debugging, the IDE contains an emulator which Mobile linux shortly termed as Moblin is an open source operating can run apps [10]. system Intel developer forum launched moblin to run on the intel atom processor in a netbook.
