- 3. • The most popular platforms today ; Android, iPhone, and Windows Mobile. • The outcomes of this are two-fold; - Firstly, it works towards developing a sustainable model for comparing mobile operating systems - Secondly, it standardises the basic architectural considerations that new entrants should adhere to. • The study is done by the comparison criteria of computer operating systems and fine-tuning it to fit the expectations of a smartphone. • The trends of Mobile O.S. is constantly increasing over the years. *ABSTRACT
- 4. • Android was initially developed by Android Inc. • Android distribution was done on 5 November 2007. • The iPhone operating system was first introduced on January 9 2007 by Apple Inc. • The Windows Mobile operating system developed by Microsoft • It was released on April 9 2000. *LITERATURE SURVEY
- 5. *INTRODUCTION •A mobile operating system (or mobile OS) is an operating system for smartphones, tablets, PDAs, or other mobile devices. •Mobile operating systems combine features of a personal computer operating system with other features useful for mobile or handheld use. •For eg. A touchscreen, cellular, Bluetooth, WiFi, GPS mobile navigation, camera, video camera, speech recognition, voice recorder, music player, near field communication and infrared blaster.
- 6. •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.
- 7. *TYPES OF MOBILE OPERATING SYSTEM •ANDROID •WINDOWS •iOS
- 8. *ANDROID
- 9. ANDROID (LOLLIPOP):- • Android architecture is made up of five parts; the Linux kernel, libraries, the runtime (Dalvik virtual machine), the application framework and applications themselves. • The application framework supports multitasking by allowing activities (a user interface component) to reside to the background while a new activity is brought to the foreground. • Each activity runs as a separate process and the pre-emptive multitasking scheduling is handled by Linux. • Android versions have been developed under a confectionery themed code name and released in alphabetical order. • Beginning with Android 1.5 “Cupcake”. • The latest update version is “Lollipop 5.1.1”.
- 10. • The earlier versions 1.0 and 1.1 were not released under specific code names: - Cupcake (1.5) - Donut (1.6) - Eclair (2.0–2.1) - Froyo (2.2–2.2.3) - Gingerbread (2.3–2.3.7) - Honeycomb (3.0–3.2.6)[a] - Ice Cream Sandwich (4.0–4.0.4) - Jelly Bean (4.1–4.3.1) - KitKat (4.4–4.4.4, 4.4W–4.4W.2) - Lollipop (5.0–5.1.1) - Marshmallow (developer preview 3) Contd….
- 11. *LOLLIPOP:- • Android Lollipop versions spanning between 5.0 and 5.1.1. released on Nov. 12, 2014. • Redesigned user interface built around Material Design. • Other changes are improved notifications, which can be accessed from the lock screen and displayed within applications as top of the screen banners. • Internal changes with the Android Runtime (ART) officially replacing Dalvik for improved application Performance. • Security and Data protection. • Lollipop is succeeded by Android Marshmallow, unveiled in May 2015, which is in a state of developer preview as of Nov. 2015.
- 12. *ARCHITECTURE
- 13. *WINDOWS
- 14. • The Windows Mobile operating system developed by Microsoft started off as Pocket PC released on April 9 2000 . • Windows Mobile is a discontinued operating system from Microsoft that it replaced with Windows Phone. • It is closed source and proprietary. • Windows is based on CE 5.2 kernel, and features a suite of basic applications developed using the Microsoft Windows API. • Versions of windows:- - Windows CE - Pocket PC 2000 - Pocket PC 2002 - Windows mobile 2003 - Windows mobile 2003 SE - Windows 5 - Windows 6 - Windows 6.1 - Windows 6.5 - Windows 8.1 WINDOWS(8.1):-
- 15. *WINDOWS MOBILE 8.1 • Action Center is well‐designed, desperately needed. • Cortana voice assistant works well considering it's still in beta. • Swipe keyboard is easy to use. • More modern hardware support. • More personalization options. • Large phones can't take full advantage of the screen space. • Google support still lagging.
- 16. *ARCHITECTURE
- 17. *APPLE iOS
- 18. *APPLE iOS (9):- • It has the second largest installed base worldwide on smartphones. • It is closed source and proprietary and built on open source Darwin core OS. • The Apple iPhone, iPod Touch, iPad and second generation Apple TV all use iOS, which is derived from OS X. • Native third party applications were not officially supported , "jailbreaking" allowed third party applications to be installed, and this method is still available. • Current iOS's version list: iPhone OS 1.x iPhone OS 2.x iPhone OS 3.x iOS 4.x iOS 5.x iOS 6.x iOS 7.x (Major UI revamp) iOS 8.x iOS 9.x
- 19. *iOS 9:- • Will work only on iPad Air 2 and later versions. • You can now chat on Skype while reading your mails. • The keyboard now doubles up as a trackpad. • Has a low battery mode similar to Android devices. • iOS 9 uses only a third of space compared to iOS 8. • Save content from browser directly to notes. • Will suggest apps based on usage habits.
