HarmonyOS (HMOS) ( zh, s=鸿蒙, p=Hóngméng, tr=Vast Mist) is a distributed operating system developed by Huawei for smartphones, tablets, smart TVs, smart watches, personal computers and other smart devices. It has a microkernel design with a single framework: the operating system selects suitable kernels from the abstraction layer in the case of devices that use diverse resources. HarmonyOS was officially launched by Huawei, and first used in Honor smart TVs, in August 2019. It was later used in Huawei wireless routers, IoT in 2020, followed by smartphones, tablets and smartwatches from June 2021. From 2019 to 2024, versions 1 to 4 of the operating system were based on code from the Android Open Source Project (AOSP) and the Linux kernel; many Android apps could be sideloaded on HarmonyOS. The next iteration of HarmonyOS became known as HarmonyOS NEXT. HarmonyOS NEXT was announced on August 4, 2023, and officially launched on October 22, 2024. It replaced the Open ...

OpenHarmony
OpenHarmony (OHOS, OH) 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, consisting of four layers from the bottom to the top: 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 in parts with other operating systems via Kernel Abstraction Layer subsystems. 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. The system contains the basic and some advanced capabilities of HarmonyOS such as DSoftBus technology with distributed device virtualization platform, tha ...

Big Business
Big business involves large-scale corporate-controlled financial or business activities. As a term, it describes activities that run from "huge transactions" to the more general "doing big things". In corporate jargon, the concept is commonly known as enterprise, or activities involving enterprise customers. The concept first rose in a symbolic sense after 1880 in connection with the combination movement that began in American business at that time. Some examples of American corporations that fall into the category of "big business" are ExxonMobil, Walmart, Google, Microsoft, Apple, General Electric, General Motors, JPMorgan Chase, Bank of America, Wells Fargo, Citigroup, and Goldman Sachs; in the United States, big businesses in general are sometimes collectively pejoratively called "corporate America". The largest German corporations included Daimler AG, Deutsche Telekom, Siemens, and Deutsche Bank. SAP is Germany's largest software company. Among the largest companie ...

Smart Home
''SMart'' was a British CBBC television programme based on art, which began in 1994 and ended in 2009. The programme was recorded at BBC Television Centre in London. Previously it had been recorded in Studio A at Pebble Mill Studios in Birmingham. The format is similar to the Tony Hart programmes '' Take Hart'' and '' Hartbeat''. The show was revamped into an hour-long show in 2007; from 1994 to 2006 it was previously a 25-minute show. From 1994 to 2005, the show also featured Morph, originally from ''Take Hart''. The series run featured 199 episodes, last airing on 11 August 2011. Production The BBC noticed the success of '' Art Attack'' with Neil Buchanan for CITV which started in 1990 and decided to create their own art show that was accessible to children similar to ''Art Attack''. The original theme tune was composed by Kjartan Poskitt, famous for the '' Murderous Maths'' series of books. From 2003, a different tune was used, written by Steve Brown (known as the fict ...

Cars
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replaced horse-drawn carriages. In Europe and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-reader
An e-reader, also called an e reader or e device, is a Mobile computing, mobile electronic device that is designed primarily for the purpose of reading digital e-books and Periodical literature, periodicals. Any device that can display text on a screen may act as an e-reader; however, specialized e-reader devices may optimize portability, readability, and battery life for this purpose. Their main advantage over printed books is portability: an e-reader is capable of holding thousands of books while weighing less than one. Another advantage is the convenience provided by add-on features. Overview An e-reader is a device designed as a convenient way to read e-books. It is similar in Form factor (design), form factor to a tablet computer, but often features electronic paper ("e-ink") rather than an LCD screen. This yields much longer battery life — the battery can last for several weeks — and better readability, similar to that of paper even in sunlight. Drawbacks of this k ...

Interactive Whiteboard
An interactive whiteboard (IWB), also known as interactive board, interactive display, interactive digital board or smart board, is a large interactive display board in the form factor of a whiteboard. It can either be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projector. They are touch screen enabled small computers. They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios, and others. The first interactive whiteboards were designed and manufactured for use in the office. They were developed by PARC around 1990. This board was used in small group meetings and round-tables. The interactive whiteboard industry was expected to reach sales of US$1 billion worldwide by 2008; one of every seven classrooms in the wor ...

Printer (computing)
A printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. He also had plans for a curve plotter, which would have been the first computer graphics printer if it was built. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augmented Reality Headset
Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory modalities, including auditory, haptic, and somatosensory. The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, through the integration of immersive sensations, which are perceived as real in the user's environment. The earliest functional AR syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wearable Devices
Wearable technology is any technology that is designed to be used while worn. Common types of wearable technology include smartwatches, fitness trackers, and smartglasses. Wearable electronic devices are often close to or on the surface of the skin, where they detect, analyze, and transmit information such as vital signs, and/or ambient data and which allow in some cases immediate biofeedback to the wearer. Wearable devices collect vast amounts of data from users making use of different behavioral and physiological sensors, which monitor their health status and activity levels. Wrist-worn devices include smartwatches with a touchscreen display, while wristbands are mainly used for fitness tracking but do not contain a touchscreen display. Wearable devices such as activity trackers are an example of the Internet of things, since "things" such as electronics, software, sensors, and connectivity are effectors that enable objects to exchange data (including data quality) through the ...

Headphones
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earphones or, colloquially, cans. Circumaural (around the ear) and supra-aural (over the ear) headphones use a band over the top of the head to hold the drivers in place. Another type, known as earbuds or earpieces, consists of individual units that plug into the user's ear canal; within that category have been developed cordless air buds using wireless technology. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of a hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
