OpenHarmony
open-in-new
<p>OpenHarmony (OHOS, OH) is a family of <a href="/facts/Open-source_software/HzTaB8E9">open-source</a> distributed operating systems based on <a href="/facts/HarmonyOS/pgEBr657">HarmonyOS</a> derived from <a href="/facts/LiteOS/cndbkkzn">LiteOS</a>, donated the L0-L2 branch source code by <a href="/facts/Huawei/Qwu0tbnL">Huawei</a> to the <a href="/facts/OpenAtom_Foundation/DEumhD21">OpenAtom Foundation</a>. Similar to HarmonyOS, the open-source <a href="/facts/Distributed_operating_system/Vm9Eu6Q4">distributed operating system</a> is designed with a layered architecture, consisting of four layers from the bottom to the top: the <a href="/facts/Kernel_(operating_system)/uEj4U3Rz">kernel</a> layer, system service layer, framework layer, and <a href="/facts/Application_software/YQuj7Kog">application</a> layer. It is also an extensive collection of <a href="/facts/Free_software/IaoVtJXn">free software</a>, which can be used as an operating system or in parts with other operating systems via Kernel Abstraction Layer subsystems. </p><p>OpenHarmony supports various devices running a mini system, such as printers, speakers, smartwatches, and other smart device with memory as small as 128 KB, or running a standard system with memory greater than 128 MB. </p><p>The system contains the basic and some advanced capabilities of HarmonyOS such as DSoftBus technology with distributed device virtualization platform, that is a departure from traditional virtualised guest OS for connected devices. </p><p>The operating system is oriented towards the <a href="/facts/Internet_of_things/rwwGAxn3">Internet of things</a> (IoT) and <a href="/facts/Embedded_devices/a4muX1wU">embedded devices</a> market with a diverse range of device support, including <a href="/facts/Smartphone/cSIrBMWG">smartphones</a>, <a href="/facts/Tablet_computer/6pGX2I7b">tablets</a>, <a href="/facts/Smart_TV/JE3CHk0y">smart TVs</a>, <a href="/facts/Smart_watch/Aq3dKhwb">smart watches</a>, <a href="/facts/Personal_computers/koaYfNce">personal computers</a> and other <a href="/facts/Smart_device/cnm7E5Vh">smart devices</a>. </p>
