OpenAtom OpenHarmony, or abbreviated as OpenHarmony (OHOS), is a family of open-source distributed operating systems based on HarmonyOS derived from LiteOS, donated the L0-L2 branch source code by Huawei to the OpenAtom Foundation. Similar to HarmonyOS, the open-source distributed operating system is designed with a layered architecture, which consists of four layers from the bottom to the top, i.e., the kernel layer, system service layer, framework layer, and application layer. It is also an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems via Kernel Abstraction Layer subsystems.[3][4]
OpenHarmony supports various devices running a mini system such as printers, speakers, smartwatches and any other smart device with memory as small as 128 KB, or running a standard system with memory greater than 128 MB.[5]
The system contains the basic and some advanced capabilities of HarmonyOS such as DSoftBus technology with distributed device virtualization platform,[6] that is a departure from traditional virtualised guest OS for connected devices.[7]
The operating system is oriented towards the Internet of things (IoT) and embedded devices market with a diverse range of device support, including smartphones, tablets, smart TVs, smart watches, personal computers and other smart devices.[8]
