 Tizen is an open source operating system based on Linux, hosted by the Linux Foundation, and open to all developers.  Tizen has evolved to connect everything, from smart TVs, smart phones, and wearable devices to IoT (Internet of Things) devices. Devices powered by Tizen can provide seamless connectivity to Tizen developers and device users among various device types.

-As diverse devices are getting smarter and more connected, there is a strong need for a software platform for integrated services with connected products. Tizen is designed for this and has been evolving to connect everything. To support different types of devices with a seamless user experience, Tizen categorizes the features and functions as profiles. There are currently 4 profiles available - IoT, TV, Mobile, and Wearable. For the IoT profile, Tizen supports both headed and headless products. In the near future, lots of Internet-connected devices are anticipated to be on the market and IoT services are expected to pervade everyone's daily life. Tizen is moving forward to the future of everything connected.

-From Tizen 3.0, all profiles are built on top of a common, shared infrastructure called **Tizen Common**. Based on the common components, devices and features under new categories or profiles can be easily added for emerging technologies. Therefore, Tizen is adaptable and customizable for new products. In the foreseeable future, for example, IoT devices and services are expected to be prevalent and Tizen is taking proactive steps toward the opportunities in these new markets.

 Users usually use multiple smart devices in various situations. Tizen enables not only connecting those devices but also leveraging every device's capabilities for providing a differentiated experience to the users.
 
-- **Supporting latest connectivity standards**: Tizen supports novel connectivity standards. The latest Wi-Fi standards like Wi-Fi Aware, Wi-Fi Easy Connect are supported by the platform and it adds support for new standards continuously. Matter and Thread protocols are the next generation IoT protocol for smart home devices. Especially, Tizen will support Matter protocol from the first release (1.0) of the open source matter SDK.

 - **Services leveraging multiple devices' capabilities**: Tizen provides easy ways of implementing services which work on multiple devices. For services on multiple devices, Tizen provides methods for discovering services among connected devices and communicating with each other in an efficient way. It is not bounded to Tizen-powered devices. Cross platform APIs are available for Tizen-Android inter-working.
-For AI services, Tizen provides a framework for offloading AI inference computation to connected high-end devices. Even when a device doesn't have enough computing power to run AI models, a service can find an alternative device to run the model among connected devices. By this feature, every Tizen device will be able to run AI services by leveraging the capability of peer devices.

 NN Runtime serves as a backend for machine learning APIs for accelerating neural network inference on Tizen devices. It supports heterogeneous computing by combining CPU and GPU, and we plan to expand support to NPU in the near future. It is based on the independent open source project [ONE (On-device Neural Engine)](https://github.com/Samsung/ONE), which consists of a runtime virtual machine running on the Tizen device and a compiler toolchain running on the developer's host computer.
