Introduction:

Introduction An operating system (OS) is an interface between hardware and user. It manages hardware and software resources of the system. An operating system which controls mobile devices is called Mobile OS. They are simple and deal with the wireless versions of broadband and local connectivity. 11/7/2013 GVPCE(A) 3

SYMBIAN OS:

SYMBIAN OS Symbian OS is a mobile operating system, developed by Symbian Ltd, in 1997. It is a mobile operating system (OS) and designed for Smartphone’s and currently maintained by Accenture. It runs exclusively on ARM processors. In June 2008, Nokia announced the acquisition of Symbian Ltd. 11/7/2013 GVPCE(A) 5

PowerPoint Presentation:

It was the most popular smartphone OS across the world till the end of 2010,untill it was overtaken by Android, although in some developing nations, Symbian is still the biggest . The current form of Symbian is an open-source platform developed by  Symbian Foundation in 2009. Symbian OS is programmed in C ++. 11/7/2013 GVPCE(A) 8

Features:

Features Processes and Threads: Symbian OS is a multitasking and multithreaded operating system . Many processes can run concurrently, can communicate with each other, and can utilize multiple threads that run internal to each process . Common File System support: Symbian OS organizes access to system storage using a file system model, just like larger Operating systems. It has a default file system compatible with windows (by default it uses FAT-32 file system ). It supports several different file systems , like FAT 16 & FAT 32, NTFS etc. 11/7/2013 GVPCE(A) 18

Contd..:

Contd.. Networking: Symbian OS supports TCP/IP networking as well as several other communication interfaces such as serial, infrared and Bluetooth . Memory Management : Although Symbian OS does not use or have the facilities for mapped virtual memory , it organizes memory access in pages and allows for the replacement of the pages, that is , bringing pages in, but not swapping them out. 11/7/2013 GVPCE(A) 19

Future Mobile OS’s :

Future Mobile OS’s Firefox OS Ubuntu Touch Tizen OS 11/7/2013 GVPCE(A) 32

Firefox OS:

Firefox OS Firefox OS is a Linux-based open source operating system for smartphones and tablet computers being developed by Mozilla . Programmed in HTML5, C++, JavaScript and CSS. The first smartphone running Firefox OS should be released in the first half of 2013 (expecting July, 2013 ). Firefox have also announced that LG Electronics, ZTE, Huawei and TCL Corporation have committed to making Firefox OS devices. 11/7/2013 GVPCE(A) 33

Ubuntu Touch:

Ubuntu Touch Ubuntu Touch  OS developed by Canonical Ltd. Ubuntu Touch aims to provide a similar user experience as the Unity desktop . Canonical aims to release handsets running the operating system by October 2013.  Ubuntu Touch devices can be equipped with a full Ubuntu session and may change into a full desktop operating system when plugged into a docking station. 11/7/2013 GVPCE(A) 34

Tizen OS :

Tizen OS Tizen is an operating system for devices including smartphones, tablets, in-vehicle infotainment (IVI) devices, and smart TVs . It is an open source system that aims to offer a consistent user experience across devices . The Tizen project resides within the Linux Foundation and is governed by a Technical Steering Group (TSG) composed of Intel and Samsung. Tizen provides an environment for application developers based on the JavaScript libraries JQuery and JQuery Mobile. 11/7/2013 GVPCE(A) 35

Conclusion:

Conclusion For developers the operating system is an ultimate platform to develop apps innovatively and publish in market very easily. Not only in mobile phones, the OS is diverging in various fields like Tabs, Smart TVs and Cameras etc. A mobile OS should be a result of factors like user experience, battery life, cloud readiness, security and openness. A successful mobile OS is a result of a design between software and hardware together. 11/7/2013 GVPCE(A) 36
