Short for High Dynamic Range Imaging, HDRI is an imaging technique that allows for a greater dynamic range of exposure than would be obtained through any normal imaging process. HDRI is now more commonly used for real photograph scenes where, for example, a large range of exposures would be found between sunlight and shadows. However, it was initially developed for use with computer-generated graphics and images. HDRI, also called HDR (High Dynamic Range) is a feature commonly found in high-end graphics and imaging software.
- high-performance computing
(n.) A branch of computer science that concentrates on developing supercomputers and software to run on supercomputers. A main area of this discipline is developing parallel processing algorithms and software: programs that can be divided into little pieces so that each piece can be executed simultaneously by separate processors.
- High Speed Packet Access
Abbreviated as HSPA, High Speed Packet Access is a set of mobile telephony protocols that includes two popular standards; HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access).
Short for high performance radio local area network. Developed by the European Telecommunications Standards Institute, HiperLAN is a set of WLAN communication standards used chiefly in European countries. HiperLAN is similar to the IEEE 802.11 WLAN standards used in the U.S. There are two types of HiperLAN: HiperLAN/1: provides communications at up to 20 Mbps […]
Short for High Performance Parallel Interface, a standard technology for physically connecting devices at short distances and high speeds. The basic flavor of HIPPI transfers 32 bits in parallel for a data transfer speed of 0.8 Gbps. Wide HIPPI transfers 64 bits at a time to yield 1.6 Gbps. New HIPPI standards supporting rates of […]
HomePlug is the name of the specification that defines the home networking technology that connects devices to each other through the power lines in a home (see power line networking). HomePlug certified products connect PCs and other devices that use Ethernet, USB and 802.11 Wi-Fi technologies to the power line via a HomePlug bridge or […]
