A computing platform, digital platform, or software platform is an environment in which software is executed. It may be the hardware or the operating system (OS), a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed using the services provided by the platform. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.
The usage share of an operating system is the percentage of computers that run that operating system (OS). These statistics are estimates as wide scale OS usage data is difficult to obtain and measure. Reliable primary sources are limited and data collection methodology is not formally agreed. Currently devices connected to the internet allow for web data collection to approximately measure OS usage.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light-weight laptops, and the hybridization of the two in 2-in-1 PCs.
The Android Package with the file extension apk is the file format used by the Android operating system, and a number of other Android-based operating systems for distribution and installation of mobile apps, mobile games and middleware. A file using this format can be built from source code written in either Java or Kotlin.
Huawei Lite OS is a discontinued lightweight real-time operating system (RTOS) developed by Huawei. It is an open source, POSIX compliant operating system for Internet of things (IoT) devices, released under a three-clause BSD license. Microcontrollers of different architectures such as ARM, x86, and RISC-V are supported by the project. Huawei LiteOS is part of Huawei's '1+8+N' Internet of Things solution, and has been featured in a number of open source development kits and industry offerings.
Servo is an experimental browser engine designed to take advantage of the memory safety properties and concurrency features of the Rust programming language. It seeks to create a highly parallel environment, in which rendering, layout, HTML parsing, image decoding, and other engine components are handled by fine-grained, isolated tasks. It also makes use of GPU acceleration to render web pages quickly and smoothly.
The Huawei Mate series, formally the Huawei Ascend Mate series, is a line of high-end HarmonyOS-powered phablet smartphones produced by Huawei, and is one of their flagship products along with the P series.
EMUI (formerly known as Emotion UI, and also known as MagicOS is a HarmonyOS/Android mobile operating system developed by Chinese technology company Huawei. It is used on the company's smartphones and tablet computers.
EulerOS is a commercial Linux distribution developed by Huawei based on Red Hat Enterprise Linux to provide an operating system for server and cloud environments. Its open-source community version is known as openEuler, of which source code was released by Huawei at Gitee on December 31, 2019 that is Multikernel based. EulerOS itself officially launched September 23, 2021 alongside to openEuler publicly on September 25, 2021.
HarmonyOS (HMOS) is a distributed operating system developed by Huawei for smartphones, tablets, smart TVs, smart watches, personal computers and other smart devices. It has a multikernel design with dual frameworks: the operating system selects suitable kernels from the abstraction layer in the case of devices that use diverse resources. The operating system was officially launched by Huawei in August 2019.
Huawei Mobile Services (HMS) is a collection of proprietary services and high level application programming interfaces (APIs) developed by Huawei Technologies Co., Ltd. Its hub known as HMS Core serves as a toolkit for app development on Huawei devices. HMS is typically installed on Huawei devices on top of running dual-framework HarmonyOS operating system, and on its earlier devices running the Android operating system with EMUI including devices already distributed with Google Mobile Services. Alongside, HMS Core Wear Engine for Android phones with lightweight based LiteOS wearable middleware app framework integration connectivity like notifications, status etc.
Celia is an artificially intelligent virtual assistant developed by Huawei for their latest HarmonyOS and Android-based EMUI smartphones that lack Google Services and a Google Assistant. The assistant can perform day-to-day tasks, which include making a phone call, setting a reminder and checking the weather. It was unveiled on 7 April 2020 and got publicly released on 27 April 2020 via an OTA update solely to selected devices that can update their software to EMUI 10.1.
Huawei AppGallery is a package manager and application distribution platform, or marketplace 'app store', developed by Huawei Technologies Co., Ltd. It serves as the official app store for devices running Huawei HarmonyOS, Huawei EMUI, Microsoft Windows is also supported via Mobile Engine emulator.
DevEco Studio is the official integrated development environment (IDE) for Huawei's HarmonyOS operating system, built on JetBrains' IntelliJ IDEA software and Huawei's SmartAssist designed specifically for HarmonyOS development. It is available for download on Microsoft Windows and macOS based operating systems.
The version history of the HarmonyOS distributed operating system began with the public release of the HarmonyOS 1.0 for Honor Vision smart TVs on August 9, 2019. The first expanded commercial version of the Embedded, IoT AI, Edge computing based operating system, HarmonyOS 2.0, was released on June 2, 2021 for phones, tablets, smartwatches, smart speakers, routers, and internet of things. Beforehand, DevEco Studio, the HarmonyOS app development IDE, was released in September 2020 together with the HarmonyOS 2.0 Beta. HarmonyOS is developed by Huawei. New major releases are announced at the Huawei Developers Conference (HDC) in the fourth quarter of each year together with the first public beta version of the operating system's next major version. The next major stable version is then released in the third to fourth quarter of the following year.
OpenAtom OpenHarmony, or abbreviated as OpenHarmony (OHOS), is a family of open-source 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.
HarmonyOS NEXT is a proprietary distributed operating system and an iteration of HarmonyOS, developed by Huawei to support only HarmonyOS native apps. The operating system is primarily aimed at software and hardware developers that deal directly with Huawei. It does not include Android's AOSP core and is incompatible with Android applications.
Huawei Ark Engine is a conglomerate of proprietary application programming interfaces (APIs) similar to Microsoft DirectX for handling tasks related to system and multimedia, especially game programming and video, on HarmonyOS platform such as Graphics engine, ArkGraphics 2D for 2D computer graphics, 2D Drawing high-performance, interactive graphics with ArkUI support and also low-level, low-overhead hardware-accelerated 3D graphic and compute shader ArkGraphics 3D API, multimedia engine for audio and video, memory engine, scheduling engine, storage engine and low power consumption engine.
ArkGraphics 3D is a low-level, low-overhead hardware-accelerated 3D graphic and compute shader API developed by Huawei as a superset of Ark Engine. It is compared to low-level APIs on other platforms such as Apple Metal, Vulkan and DirectX 12.
BiSheng Compiler is an open-source compiler toolchain developed by Huawei for general-purpose processor architectures, such as Kunpeng within HiSilicon domain. It introduces and enhances multiple compilation optimization technologies and supports different programming languages, such as ArkTS, Cangjie, C, C++ and Fortran.
