Symbian was established by leaders in the computing and mobile industries to enable the mass market of communicators and smart phones. Symbian owns and develops the Symbian operating system that is optimized for mobile terminals, such as communicators and smart phones.

Symbian OS enables
* Small, feature-rich, mobile devices for a mass market
* Diversity of devices for consumers
* Faster time-to-market for platform vendors
* Open, standards-based platform for third-party application developers
* Excellent connectivity
* Advanced design
* Extensibility
* High-performance, 32-bit OS with pre-emptive multitasking
* Long battery life
* Wide industry support and commitment
* Applications that can be designed once and run on multiple devices
* Nokia Series 60 and communicator platforms are based on Symbian OS

As Symbian OS is written in C++, it is a fully object-oriented operating system. This contributes to its flexibility, efficiency ,and ability to re-use segments of the code. Clearly defined APIs allow the large developer community, including terminal vendors, to create applications that can be easily downloaded, installed, and run natively on the terminal Symbian OS. Symbian C++ APIs enable extremely efficient multitasking and memory management. Processor-and memory-intensive operations such as context switching are minimized.

Symbian OS is primarily event driven rather than multithreaded, potentially saving several kilobytes of overhead per thread. The event-driven Symbian OS doesn't need any context switching and can have an overhead as low as a few tens of bytes.
