Home servers are used to aggregate storage on consumer home networks. Although similar to less-expensive home network-attached storage (NAS) devices, home servers are more sophisticated devices geared to aggregating a broader range of services on a home network. These services center on storage/media streaming (e.g., music, photos and videos) and home PC backup, but also include Internet gateway services, as well as remote access to home PCs.

Database in a wireless network containing customer data, including service entitlements and call-routing information. In combination with the International Mobile Subscriber Identity (IMSI), it provides the network mechanism for the cell-to-cell handover of calls and for local and international roaming.

Home health monitoring is the use of IT and telecommunications to monitor the health of patients in their homes and to help ensure that appropriate action is taken. Patients are provided devices that measure vital signs, such as blood pressure, glucose level, pulse, blood oxygen level and weight, and then transmit the data to clinicians. Other devices are used for messaging — gathering information from patients on their symptoms, cognitive state and behavior, and sending them information and advice.

An individual visit to a website or Web page, expressed as a measure of its popularity (i.e., Web traffic volume). For example, a site that had 48,000 visitors during a 24-hour period might be said to have averaged 2,000 “hits” per hour during that period.

Historian software captures the output of operational technology systems and manages its life cycle, and provides access for and performing some levels of data analysis.

High-temperature superconductivity is a technology that facilitates the use of ceramic materials for conducting and transmitting electricity with little or no resistance loss without the need to achieve low-temperature superconductivity. Despite its name, high-temperature superconductivity still occurs at cryogenic temperatures. The main difference from low-temperature superconductivity, which is usually achieved at or near the absolute zero temperature (minus 273 degrees Celsius), is that high-temperature superconductors (HTSs) can use liquid nitrogen (at minus 196 degrees Celsius) as a coolant.

High-speed color inkjet technology enables printing in excess of 150 letter-size pages per minute (ppm) using stationary print heads. Multiple banks of print heads are used to print colors individually or in combination to produce process color images.

High-performance computing (HPC) clusters can be composed of large numbers of servers, where the total physical size, energy use or heat output of the computing cluster might become a serious issue. Furthermore, there are requirements for dedicated communications among the servers that are somewhat unique to clusters. Because small design differences amount to large benefits when multiplied by the number of servers in the clusters, we are seeing the emergence of server designs that are optimized for HPC. Sometimes these are designs targeted at large, public Web operators, such as search engine firms, that deliver similar benefits in HPC clusters, but they can also offer features only appropriate for HPC users. For example, if the system were designed to provide the cluster interconnect differently, there might be a significant cabling reductions possible.

A two-color printing scheme found in some transactional documents, such as bills and statements. Black is the first color. The second color is used for emphasis or to highlight important information, such as the due date. The second color can also be used to match the corporate color scheme, in which the company name, logo or other elements are printed. Gartner classifies highlight color devices as “monochrome” in the market data and forecast estimates it publishes.

High-definition (HD) voice is also known as wideband voice. Compared to traditional telephony voice over public switched telephone networks (PSTNs) and cellular, HD voice uses double the sampling rate, reproducing a much larger sound frequency and delivering all, or most, of the frequencies of a user’s voice. HD voice’s major advantage is the ability to communicate with clearer audio and have improved and more intelligible conversations over fixed line, cellular networks and voice over Internet Protocol (VoIP).
