Short for High Floppy Disk, a type of high-density floppy disk developed by Sony that can hold 200 MB of data. Like the competing SuperDisk disk drive from Imation, HiFD disk drives can read and write old 1.44 MB floppy disks in addition to the new high-density disks. HiFD drives support data transfer rates of up to 3.6 MBps.
- High Availability
High Availability, or HA as it is abbreviated, refers to the availability of resources in a computer system, in the wake of component failures in the system. This can be achieved in a variety of ways, spanning the entire spectrum ranging at the one end from solutions that use custom and redundant hardware to ensure […]

See under High Dynamic Range Imaging (HDRI).
- High Dynamic Range Imaging
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, […]
- 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).
