- grandfather, father, son — (operating system) (GFS) A backup rotation scheme in which a "grandfather" backup is performed on the first Monday of each month, a "father" backup is performed on every other Monday and a "son" backup is performed on every other day of the week. Grandfather tapes are kept for a year, father tapes for a month and son tapes for a week. The exact schedule (and thus the number of tapes required) may vary, as may the choice of full backup or incremental backup, but the idea is that it should be possible to restore versions of any file of different ages: e.g. yesterday's, last week's or last year's version.

- hierarchical data format — (file format, data) (HDF) A library and multi-object file format for the transfer of graphical and numerical data between computeres. The freely available HDF distribution consists of the library, command line utilities, test suite source, Java interface, and the Java-based HDF Viewer (JHV). HDF supports several different data models, including multidimensional arrays, raster images, and tables. Each defines a specific aggregate data type and provides an API for reading, writing, and organising the data and metadata. New data models can be added by the HDF developers or users. HDF is self-describing, allowing an application to interpret the structure and contents of a file without any outside information. One HDF file can hold a mixture of related objects which can be accessed as a group or as individual objects. Users can create their own grouping structures called "vgroups". HDF files can be shared across most common platforms, including many workstations and high performance computers. An HDF file created on one computer can be read on a different system without modification.
- high bypass ratio engine — a type of by-pass engine in which a large fan driven by a turbine and housed in a short duct forces air rearwards around the exhaust gases in order to increase the propulsive thrust
- high performance fortran — (language) (HPF) A data parallel language extension to Fortran 90 which provides a portable programming interface for a wide variety of target platforms. The original HPF language specification was produced by the High Performance Fortran Forum, a broad consortium of industry and academia, which met regularly throughout 1992 and early 1993. HPF compilers are now available on most commonly-used computing systems, and users are beginning to gain first hand experience with this language. The Forum has continued to meet in order to address advanced topics.
- high performance routing — (networking) (HPR) Routing designed to work in conjunction with APPN Intermediate Session Routing (ISR) network nodes. HPR nodes perform many of the same functions as ISR nodes. For example, HPR nodes use the same method of calculating routes based on the Topology Routing Service database and class of service tables. HPR nodes also supports such APPN features as connection networks and support for parallel transmission groups (TGs). In the HPR architecture, both partner nodes must support HPR for RTP connections to take place between the nodes. If one node supports HPR and the partner node does not, then the link will support ISR functionality only.

- house of representatives — the lower legislative branch in many national and state bicameral governing bodies, as in the United States, Mexico, and Japan.

- ichthyophthirius-disease — ich.
- in one's heart of hearts — Anatomy. a hollow, pumplike organ of blood circulation, composed mainly of rhythmically contractile smooth muscle, located in the chest between the lungs and slightly to the left and consisting of four chambers: a right atrium that receives blood returning from the body via the superior and inferior vena cavae, a right ventricle that pumps the blood through the pulmonary artery to the lungs for oxygenation, a left atrium that receives the oxygenated blood via the pulmonary veins and passes it through the mitral valve, and a left ventricle that pumps the oxygenated blood, via the aorta, throughout the body.

Instructional technology aims to promote the application of validated, practical procedures in the design and delivery of instruction. It is often defined either in terms of media and other technology used (e.g. audiovisual media and equipment and computers), or in terms of a systematic process which encompasses instructional design, development, delivery and evaluation.

- macintosh user interface — (operating system) The graphical user interface used by Apple Computer's Macintosh family of personal computers, based on graphical representations of familiar office objects (sheets of paper, files, wastepaper bin, etc.) positioned on a two-dimensional "desktop" workspace. Programs and data files are represented on screen by small pictures (icons). An object is selected by moving a mouse over the real desktop which correspondingly moves the pointer on screen. When the pointer is over an icon on screen, the icon is selected by pressing the button on the mouse. A hierarchical file system is provided that lets a user "drag" a document (a file) icon into and out of a folder (directory) icon. Folders can also contain other folders and so on. To delete a document, its icon is dragged into a trash can icon. For people that are not computer enthusiasts, managing files on the Macintosh is easier than using the MS-DOS or Unix command-line interpreter. The Macintosh always displays a row of menu titles at the top of the screen. When a mouse button is pressed over a title, a pull-down menu appears below it. With the mouse button held down, the option within the menu is selected by pointing to it and then releasing the button. Unlike the IBM PC, which, prior to Microsoft Windows had no standard graphical user interface, Macintosh developers almost always conform to the Macintosh interface. As a result, users are comfortable with the interface of a new program from the start even if it takes a while to learn all the rest of it. They know there will be a row of menu options at the top of the screen, and basic tasks are always performed in the same way. Apple also keeps technical jargon down to a minimum. Although the Macintosh user interface provides consistency; it does not make up for an application program that is not designed well. Not only must the application's menus be clear and understandable, but the locations on screen that a user points to must be considered. Since the mouse is the major selecting method on a Macintosh, mouse movement should be kept to a minimum. In addition, for experienced typists, the mouse is a cumbersome substitute for well-designed keyboard commands, especially for intensive text editing.
- magnetothermoelectricity — thermoelectricity induced or affected by a magnetic field.
- maker interchange format — (MIF) A language used to describe a FrameMaker document in a text file. MIF is used to exchange information between FrameMaker and other applications.

- neutrosophic probability — (logic) An extended form of probability based on Neutrosophy, in which a statement is held to be t true, i indeterminate, and f false, where t, i, f are real values from the ranges T, I, F, with no restriction on T, I, F or the sum n=t+i+f.
