What is Symbian?

• An proprietary operating system for mobile devices and smartphones by Symbian Ltd.

• Symbian is the world's most popular mobile operating system, accounting for 50% of smartphone sales in Q2 2009.

• The process of publishing the source code under the Eclipse Public License (EPL) was slated for completion in 2010.

Symbian’s HistoryYear Event

1980 Psion founded by David Potter

1984 Psion Organiser launched

1986 the "vastly improved" Psion Organiser II launches, with a simple-to-use database programming language, OPL.

1987 Psion begins development of its “SIBO" family of devices and its own new multitasking operating system called EPOC to run its PDA products.

1989 First EPOC16 devices, the MC400 and MC200, ship with a primarily 1-bit, keyboard-operated graphical interface.

1997 The first version of EPOC32 Release 1 appeared on the Psion Series 5 ROM v1.0. The EPOC32 operating system, at the time simply referred to as EPOC, was later renamed Symbian OS. EPOC32 was a pre-emptive multitasking, single user operating system with memory protection, which encourages the application developer to separate their program into an engine and an interface.

1998 In June Psion Software became Symbian, a major joint venture between Psion and phone manufacturers Ericsson, Motorola, and Nokia. As of Release 6, EPOC became known simply as Symbian OS.

1999 The Psion Series 5mx, Psion Series 7, Psion Revo, Diamond Mako, Psion netBook, netPad, GeoFox One, and Ericsson MC218 were released using ER5. A phone project was announced at CeBIT, the Phillips Illium/Accent, but did not achieve a commercial release.

2000 The first phone, the Ericsson R380 was released using ER5u in November.

2001 The first 'open' Symbian OS phone, the Nokia 9210 Communicator, was released in June 2001. Bluetooth support was added. Almost 500,000 Symbian phones were shipped in 2001, rising to 2.1 million the following year.

2003 First shipment of Symbian OS 7.0 and 7.0s, an important Symbian release which appeared with all contemporary user interfaces including UIQ, Series 80, Series 90, Series 60 as well as several FOMA phones in Japan. It also added EDGE support and IPv6. One million Symbian phones were shipped in Q1 2003, with the rate increasing to one million a month by the end of 2003.

2004 Psion sells its stake in Symbian.

2006 100 millionth phone with Symbian OS is shipped.

2008 Symbian acquired by Nokia; Symbian Foundation formed.

Android’s History

Handset layouts

The platform is adaptable to larger, VGA, 2D graphics library, 3D graphics library based on OpenGL ES 1.0 specifications, and traditional smartphone layouts.

Storage The Database Software SQLite is used for data storage purposes

Connectivity Android supports connectivity technologies including GSM/EDGE, CDMA, EV-DO, UMTS, Bluetooth, and Wi-Fi.

Messaging SMS and MMS are available forms of messaging including threaded text messaging.

Web browser The web browser available in Android is based on the open-source WebKit application framework. The browser scores a 93/100 on the Acid3 Test.

Java support Software written in Java can be compiled to be executed in the Dalvik virtual machine, which is a specialized VM implementation designed for mobile device use, although not technically a standard Java Virtual Machine.

Media support Android supports the following audio/video/still media formats: H.263, H.264 (in 3GP or MP4 container), MPEG-4 SP, AMR, AMR-WB (in 3GP container), AAC,HE-AAC (in MP4 or 3GP container), MP3, MIDI, OGG Vorbis, WAV, JPEG, PNG, GIF, BMP.

Additional hardware suuport

Android can use video/still cameras, touchscreens, GPS, accelerometers, magnetometers, accelerated 2D bit blits (with hardware orientation, scaling, pixel format conversion) and accelerated 3D graphics.

Development environment

Includes a device emulator, tools for debugging, memory and performance profiling, a plugin for the Eclipse IDE.

Market Like many phone-based application stores, the Android Market is a catalog of applications that can be downloaded and installed to target hardware over-the-air, without the use of a PC. Originally only freeware applications were supported. Paid-for apps have been available on the Android Market in the United States since 19 February 2009. [36] The Android Market has been expanding rapidly. By December, 2009, it had over 20,000 Android applications for download.

Muti-touch Android has native support for multi-touch which is available in newer handsets such as the HTC Hero. The feature was initially disabled at the kernel level (possibly to avoid infringing Apple patents on touch-screen technology)

Android’s Features

• Application framework enabling reuse and replacement of components

• Dalvik virtual machine optimized for mobile devices• Integrated browser based on the open

source WebKit engine• Optimized graphics powered by a custom 2D graphics

library; 3D graphics based on the OpenGL ES 1.0 specification

• SQLite for structured data storage• Media support for common audio, video, and still image

formats • GSM Telephony• Bluetooth, EDGE, 3G, and WiFi• Camera, GPS, compass, and accelerometer• Rich development environment including a device

emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE
