Hacker culture
The hacker culture is a subculture of individuals who enjoy the intellectual challenge of creatively overcoming limitations of software systems to achieve novel and clever outcomes.[1] The act of engaging in activities (such as programming or other media[2]) in a spirit of playfulness and exploration is termed “hacking”. However, the defining characteristic of a hacker is not the activities performed themselves (e.g. programming), but the manner in which it is done[3] and whether it is something exciting and meaningful.[2] This culture began back in the 1960s at MIT, where students banded together to release information on the internet they thought should be public information. Often referred to as, “computer-science freaks.”[4]
Richard Stallman explains about hackers who program:
What they had in common was mainly love of excellence and programming. They wanted to make their programs that they used be as good as they could. They also wanted to make them do neat things. They wanted to be able to do something in a more exciting way than anyone believed possible and show “Look how wonderful this is. I bet you didn’t believe this could be done.”
People in hacker culture have a unique desire to practice their skills while simultaneously trying to have fun like children.[6]

Haptic technology
Haptic technology, also known as kinaesthetic communication or 3D touch,[1] refers to any technology that can create an experience of touch by applying forces, vibrations, or motions to the user.[2] These technologies can be used to create virtual objects in a computer simulation, to control virtual objects, and to enhance remote control of machines and devices (telerobotics). Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. The word haptic, from the Greek: ἁπτικός (haptikos), means “tactile, pertaining to the sense of touch”. Simple haptic devices are common in the form of game controllers, joysticks, and steering wheels.

Hard disk drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk[b] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data even when powered off.

Health data
Health data is any data “related to health conditions, reproductive outcomes, causes of death, and quality of life”[1] for an individual or population. Health data includes clinical metrics along with environmental, socioeconomic, and behavioral information pertinent to health and wellness. A plurality of health data are collected and used when individuals interact with health care systems. This data, collected by health care providers, typically includes a record of services received, conditions of those services, and clinical outcomes or information concerning those services.[2] Historically, most health data has been sourced from this framework. The advent of eHealth and advances in health information technology, however, have expanded the collection and use of health data—but have also engendered new security, privacy, and ethical concerns. The increasing collection and use of health data by patients is a major component of digital health.

Health information technology
Health information technology (HIT) is health technology, particularly information technology, applied to health and health care. It supports health information management across computerized systems and the secure exchange of health information between consumers, providers, payers, and quality monitors.[1] Based on an often-cited 2008 report on a small series of studies conducted at four sites that provide ambulatory care – three U.S. medical centers and one in the Netherlands – the use of electronic health records (EHRs) was viewed as the most promising tool for improving the overall quality, safety and efficiency of the health delivery system.[2] According to a 2006 report by the Agency for Healthcare Research and Quality, in an ideal world, broad and consistent utilization of HIT would:[3][not specific enough to verify]
improve health care quality or effectiveness
increase health care productivity or efficiency
prevent medical errors and increase health care accuracy and procedural correctness
reduce health care costs
increase administrative efficiencies and healthcare work processes
decrease paperwork and unproductive or idle work time
extend real-time communications of health informatics among health care professionals

High-definition television
High-definition television (HD) describes a television system providing an image resolution of substantially higher resolution than the previous generation of technologies. The term has been used since 1936,[1] but in modern times refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television, and Blu-ray Discs.

High-end audio
High-end audio is a class of consumer home audio equipment marketed to audiophiles on the basis of high price or quality, and esoteric or novel sound reproduction technologies. The term can refer simply to the price, to the build quality of the components, or to the subjective or objective quality of sound reproduction.
Definition
The distinction between the terms high end and high fidelity is not well defined.[3] According to one industry commentator, high-end could be defined as, “Gear below which’s price and performance one could not go without compromising the music and the sound.”[4] Harry Pearson, founder of The Absolute Sound magazine, is widely acknowledged to have coined the term high-end audio.

High-resolution audio
High-resolution audio (High-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, there also exist 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings that are labeled HD Audio.
Research into high resolution audio began in the late 1980s and high resolution audio content started to become available on the consumer market in 1996.
High-resolution audio is generally used to refer to music files that have a higher sampling frequency and/or bit depth than that of Compact Disc Digital Audio (CD-DA), which operates at 44.1 kHz/16-bit.

Hologram
A hologram is a physical recording of an interference pattern which uses diffraction to reproduce a three-dimensional light field, resulting in an image which retains the depth, parallax, and other properties of the original scene. Holography is the science and practice of making holograms. A hologram is a photographic recording of a light field, rather than an image formed by a lens. The holographic medium, i.e., the object produced by a holographic process (which itself may be referred to as a hologram) is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of variations in the opacity, density, or surface profile of the photographic medium. When suitably lit, the interference pattern diffracts the light into an accurate reproduction of the original light field, and the objects that were in it exhibit visual depth cues such as parallax and perspective that change realistically with the relative position of the observer. That is, the view of the image from different angles represents the subject viewed from similar angles.In this sense, holograms do not simply produce the illusion of depth but are truly three-dimensional images.

Home appliance
A home appliance, also referred to as a domestic appliance, an electric appliance or a household appliance, is a machine which assists in household functions such as cooking, cleaning and food preservation.
Appliances are divided into three types:
- small appliances;
- major appliances, or white goods;
- and consumer electronics, or brown goods.
This categorization is reflected in the maintenance and repair of these types of products. Brown goods typically require high technical knowledge and skills (which get more complex with time, such as going from a soldering iron to a hot-air soldering station), while white goods may need more practical skills and force to manipulate the devices and heavy tools required to repair them.

Home automation
Home automation or domotics[1] is building automation for a home, called a smart home or smart house. A home automation system will monitor and/or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems. When connected with the Internet, home devices are an important constituent of the Internet of Things (“IoT”).
A home automation system typically connects controlled devices to a central hub or “gateway”. The user interface for control of the system uses either wall-mounted terminals, tablet or desktop computers, a mobile phone application, or a Web interface that may also be accessible off-site through the Internet.
While there are many competing vendors, there are increasing efforts towards open source systems. However, there are issues with the current state of home automation including a lack of standardized security measures and deprecation of older devices without backwards compatibility.
Home automation has high potential for sharing data between family members or trusted individuals for personal security and could lead to energy saving measures with a positive environmental impact in the future.
The home automation market was worth US$5.77 billion in 2013, predicted to reach a market value of US$12.81 billion by the year 2020.[2]

Home cinema
Home cinema, also called home theaters or theater rooms, are home entertainment audio-visual systems that seek to reproduce a movie theater experience and mood using consumer electronics-grade video and audio equipment that is set up in a room or backyard of a private home. In the 1980s, home cinemas typically consisted of a movie pre-recorded on a LaserDisc or VHS tape; a LaserDisc or VHS player; and a heavy, bulky large-screen cathode ray tube TV set, although sometimes CRT projectors were used instead. In the 2000s, technological innovations in sound systems, video player equipment and TV screens and video projectors have changed the equipment used in home cinema set-ups and enabled home users to experience a higher-resolution screen image, improved sound quality and components that offer users more options (e.g., many of the more expensive Blu-ray players in 2016 can also “stream” movies and TV shows over the Internet using subscription services such as Netflix). The development of Internet-based subscription services means that 2016-era home theatre users do not have to commute to a video rental store as was common in the 1980s and 1990s (nevertheless, some movie enthusiasts buy DVD or Blu-ray discs of their favourite content)

Host (network)
A network host is a computer or other device connected to a computer network. A host may work as a server offering information resources, services, and applications to users or other hosts on the network. Hosts are assigned at least one network address.
A computer participating in networks that use the Internet protocol suite may also be called an IP host. Specifically, computers participating in the Internet are called Internet hosts. Internet hosts and other IP hosts have one or more IP addresses assigned to their network interfaces. The addresses are configured either manually by an administrator, automatically at startup by means of the Dynamic Host Configuration Protocol (DHCP), or by stateless address autoconfiguration methods.
Network hosts that participate in applications that use the client–server model of computing, are classified as server or client systems. Network hosts may also function as nodes in peer-to-peer applications, in which all nodes share and consume resources in an equipotent manner.

HTC
HTC Corporation (traditional Chinese: 宏達國際電子股份有限公司; simplified Chinese: 宏达国际电子股份有限公司; pinyin: Hóngdá Guójì Diànzǐ Gǔfèn Yǒuxiàn Gōngsī) (High Tech Computer Corporation, literally Hongda International Electronics Co., Ltd.; trading as HTC) is a Taiwanese consumer electronics company headquartered in Xindian District, New Taipei City, Taiwan. Founded in 1997, HTC began as an original design manufacturer and original equipment manufacturer, designing and manufacturing laptop computers.[2]
After initially making smartphones based mostly on Windows Mobile, HTC became a co-founding member of the Open Handset Alliance, a group of handset manufacturers and mobile network operators dedicated to the development of the Android mobile operating system. The HTC Dream (marketed by T-Mobile in many countries as the T-Mobile G1) was the first phone on the market to run Android.
Although initially successful as a smartphone vendor, competition from Apple Inc. and Samsung Electronics, among others, diluted its market share, which reached just 7.2% by April 2015, and the company has experienced consecutive net losses. In 2016, HTC began to diversify its business beyond smartphones, having partnered with Valve to produce a virtual reality platform known as HTC Vive. After having collaborated with Google on its Pixel smartphone, HTC sold roughly half of its design and research talent, as well as non-exclusive rights to smartphone-related intellectual property, to Google in 2017 for US$1.1 billion.

Human–computer interaction
Human–computer interaction (HCI) studies the design and use of computer technology, focused on the interfaces between people (users) and computers. Researchers in the field of HCI observe the ways in which humans interact with computers and design technologies that let humans interact with computers in novel ways.
As a field of research, human-computer interaction is situated at the intersection of computer science, behavioural sciences, design, media studies, and several other fields of study. The term was popularized by Stuart K. Card, Allen Newell, and Thomas P. Moran in their seminal 1983 book, The Psychology of Human–Computer Interaction, although the authors first used the term in 1980 and the first known use was in 1975. The term connotes that, unlike other tools with only limited uses (such as a wooden mallet, useful for hitting things, but not much else), a computer has many uses and this takes place as an open-ended dialog between the user and the computer. The notion of dialog likens human–computer interaction to human-to-human interaction, an analogy which is crucial to theoretical considerations in the field.

Hybrid electric vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system (hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist.

Hybrid vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids.
The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed (better than a typical electric motor). Switching from one to the other at the proper time while speeding up yields a win-win in terms of energy efficiency, as such that translates into greater fuel efficiency, for example.
https://en.m.wikipedia.org/wiki/Hybrid_vehicle
Hybrid vehicle drivetrain
Hybrid vehicle drive trains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power.
Hybrids come in many configurations. For example, a hybrid may receive its energy by burning petrol, but switch between an electric motor and a combustion engine.
Electrical vehicles have a long history combining internal combustion and electrical transmission – as in a diesel–electric power-train – although they have mostly been used for rail locomotives. A diesel–electric powertrain fails the definition of hybrid because the electric drive transmission directly replaces the mechanical transmission rather than being a supplementary source of motive power. One of the earliest forms of hybrid land vehicle was the ‘trackless’ trolleybus experiment in The United States (New Jersey) that ran from 1935 to 1948, which normally used traction current delivered by wire. The trolleybus was fitted with an internal combustion engine (ICE) to power the mechanical drivetrain directly, not to generate electricity for the traction motor. This enabled the vehicle to be used for revenue service where there was no contact wire. Since the 1990s trolleybus hybrids have been introduced with small power plants to provide a low speed capability for emergency and maintenance but not to support general revenue service.

Hyperlink
In computing, a hyperlink, or simply a link, is a reference to data that the user can follow by clicking or tapping.[1] A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is called anchor text. A software system that is used for viewing and creating hypertext is a hypertext system, and to create a hyperlink is to hyperlink (or simply to link). A user following hyperlinks is said to navigate or browse the hypertext.
The document containing a hyperlink is known as its source document. For example, in an online reference work such as Wikipedia, or Google, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanisms such as tables of contents, footnotes, bibliographies, indexes, letters and glossaries.
In some hypertext, hyperlinks can be bidirectional: they can be followed in two directions, so both ends act as anchors and as targets. More complex arrangements exist, such as many-to-many links.
