Symbian OS

Dear Friends I’m back today with yet another topic for you.

Today I’m going to explain you something about Symbian OS what was it before a Symbian OS and how it is evolved?

Nowadays we all own a cellphone does anybody think that there can be an operating system in the mobile phones? OK leaving that question apart today there are various different kind of smart phones are available in market (there is a long lasting list). So all these smart phones run on some operating system viz iOS(Apple smart phones), Maemo(Linux based OS), Symbian, Java, Android, Windows Mobile etc.

Symbian is the descended from the EPOC family of operating system which is developed for Portable Devices by Psion. There were various version of EPOC in the market. In 1998 Psion Software became Symbian Ltd with the Nokia, Motorolla and Ericsson. and after which the next release of the EPOC was named as Symbian OS though this was first symbian os still its version was 6.0 then the next version was 6.1 and other various versions were launched 7.0 , 8.0 ,9.0 to 9.5 but the revolution was 9.2 which was used in Eseries and Nseries phones. Now the latest version of Symbian is Symbian^3.

Security is one of the most important criteria in an operating system.Symbian OS was subject to a variety of viruses.However, with a view that the average mobile phone user shouldn’t have to worry about security.

Symbian was the first platform specifically developed for smartphones – it started the smartphone revolution and remains at the heart of the people. The Symbian platform is used by more people in more places than any other mobile OS, making Symbian the most popular smartphone platform on the planet.The Symbian platform gives you the power to do more with mobile. The code of symbian is freely available so anyone can redesign and build the operating system for mobile device. Symbian OS are packaged in .sis format and can be installed by any way which is available bluetooth, via PC etc. In 2008 Symbian Ltd was acquired by Nokia and new independent Symbian Foundation was established.

The Symbian OS features multitasking and storage protection, to save the time and the most important is security of data.Symbian uses a microkernel, has a request-and-callback approach to services, and maintains separation between user interface and engine. The OS is optimised for low-power battery-based devices and for ROM-based systems.

Symbian devices can also be programmed using Python, Java ME, Flash Lite, Ruby, .NET, Web Runtime (WRT) Widgets and Standard C/C++.As of 2010, the SDK for Symbian is standard C++, using Qt. It can be used with either Qt Creator, or Carbide A phone simulator allows testing of Qt apps. Apps compiled for the simulator are compiled to native code for the development platform.
