It was presented in Silicon Institute of Technology ,Bhubaneswar English Lab

It's very professional and not exaggerated with unnecessary effects....

1. Open source mobile operating systems By:- Ananya Dash Deeptiman Mallick Santosmita Panda Swayansidha Gantayat

2. Operating system An essential component of computer system An interface between user and system A software that provides common service for computer programs Manages computer hardwares and softwares Application softwares require Operating System to function

3. Operating System Acts as an intermediate between programs and hardwares for input/output and memory allocation Any device having an computerized system has an Operating System Ex:-cellular phones ,Game console ,super computers & web servers Examples of some popular modern operating systems are:- Microsoft Windows ,Mac OS X ,Linux ,UNIX , Android ,Windows Phone, iOS etc.

4. Types of Operating System Real Time Distributed Multi User Templated Embedded

5. Mobile Operating System An operating system that operates m obile devices Combines features of personal computer OS with cellular and other features required for a mobile deice user

6. Open Source A computer program in which the source code is available to the general public General public has right to modify, re-distribute and re-invent. Main principle is peer production by collaboration with end product blue prints And to avail documentation an no cost to the public. Most of the open source mobile operating systems are based on LINUX kernel

7. Kernel Fundamental part of modern Operating Systems Manages input/output from softwares The part of operating system that directly interacts with hardwares Translates signals into data processing instruction for the CPU and other components . Decides which programs should be allocated to which process

8. ANDROID

9. Android OS Mobile OS based on Linux kernel Primarily developed for mobile devices Was unveiled in 2007 along with the foundation of O pen handset Alliance

10. Invention & Development Invented by Andy Rubin in 2003 Android Inc. was founded by Andy Rubin, Rich Miner, Nick Sears and Chris White Google acquired Android in 2005 In 2006 a version with code name “Sooner” was released. On 5 th November 2007, Open handset Alliance was founded by taking Google along with handset makers HTC, Samsung ,Sony Wireless service providers Nextel, T-Mobile, and Chipset makers Qualcomm and Texas Instruments.

11. Invention & Development The first product of Android as a Open Source platform for Mobile device was released running on LINUX kernel version 2.6.25 The first smartphone running Android was HTC Dream released on 22 nd October 2008 Google launched Nexus series device in 2010

16. Pull-Down menu This picture shows “pull down menu” of an mobile device running Android 4.4.2 Kitkat.

17. Android Apps Apps are developed by using Android SDK It uses Java programming language But now, using Android NDK and Eclipse IDE Android apps can be developed using C/C++ Before that ADT needs to be installed

18. Android Apps stores Amazon App Store Mobogenie

19. Android Apps stores As per a blog post by Larry Page, 50 billions apps were installed in G oogle Play till June 2013

20. Android kernel Android is based on LINUX kernel Kernel is written in C & C++ Android kernel is also called Monolithic/Modified LINUX Kernel First Android Kernel version was Ver. 2.6.25 Current Android versions run on LINUX kernel Ver. 3.4

21. Android kernel

22. Multi-platform use Android was first developed as open source mobile OS But currently also being used in other platforms Android Wear, Android TV etc. are used in Smart watches and Televisions Android is also used in PCs and game consoles

23. Multi-Platform use

24. Achievements

25. achievements As of 2011 Android is the largest installed mobile OS As of 2013 Android devices sell more than Windows, iOS & Mac OS combined 71% developers develop apps for Android devices As of July 2013 the Google Play Store had over one million apps published and 50 billions installed

26. FIREFOX OS

27. Firefox OS A LINUX kernel based open-source OS for Smartphones , Tablets , and Smart TV. Developed by Mozilla corporation. Designed to provide a complete community-based OS for mobile devices using open standard & approaches

28. Development History On 25 th July 2011 ,Andreas Gal, Director of research at Mozilla announced the Boot to Gecko project In July 2012 ,B2G was rebranded as Firefox OS In February 2013 ,Mozilla announced availability of Firefox OS device in Brazil, Colombia, Hungary, Mexico, Poland, Sebia ,Spain , & Venzuela

29. Development History LG, ZTE , Huawei & TLC are committed to make Firefox OS devices On 2 nd July 2013 ,ZTE launched first Firefox OS device ZTE Open Spice launched Spice Fire One ,The first Firefox OS phone in India.

33. UBUNTU TOUCH

34. Ubuntu Touch OS Mobile version of popular Ubuntu operating system Developed by Canonical UK Ltd. and Ubuntu community. Primarily designed for touch screen mobile devices such as smartphones and tablet computers Ubuntu 14.04 support for mobile devices was announced by Mark Shuttle Werth on 31 st October 2011 Ubuntu 13.10 released on 17 th October 2013 which the Galaxy Nexus and Nexus 4 phones A Google edition of it also available for installation on android handsets including Samsung Galaxy S4

35. Features Uses QT-5 based touch user interface Also can often used with LINUX kernel used in Androids Uses same core technology as the Ubuntu Desktop Ubuntu Desktop can be interchanged to Ubuntu touch device by connecting it to docking station Also Ubuntu touch can be inverted into full desktop by connecting it to external monitor Doing office work and playing ARM-ready game can be done on such device

36. Ubuntu touch interface This picture shows the UI of Ubuntu Touch OS shown in developer’s preview
