  • harvard architecture — (architecture)   A computer architecture in which program instructions are stored in different memory from data. Each type of memory is accessed via a separate bus, allowing instructions and data to be fetched in parallel. Contrast: von Neumann architecture.
  • hierarchical routing — The complex problem of routing on large networks can be simplified by breaking a network into a hierarchy of smaller networks, where each level is responsible for its own routing. The Internet has, basically, three levels: the backbones, the mid-levels, and the stub networks. The backbones know how to route between the mid-levels, the mid-levels know how to route between the sites, and each site (being an autonomous system) knows how to route internally. See also Exterior Gateway Protocol, Interior Gateway Protocol, transit network.
  • hipparchus satellite — an astronometric satellite launched in 1989 by the European Space Agency that measured the position, proper motion, and brightness of 118 218 stars down to 12th magnitude and the magnitude and colour of a million stars down to 10th magnitude
  • hire-purchase system — a system of payment for a commodity in regular installments while using it.
  • hit the panic button — an alarm button for use in an emergency, as to summon help.
  • hit-and-run accident — a motor-vehicle accident in which the driver leaves the scene without stopping to give assistance, inform the police, etc
  • honeysuckle ornament — anthemion.
  • hot under the collar — the part of a shirt, coat, dress, blouse, etc., that encompasses the neckline of the garment and is sewn permanently to it, often so as to fold or roll over.
  • human genome project — a federally funded U.S. scientific project to identify both the genes and the entire sequence of DNA base pairs that make up the human genome.
  • hydrostatic pressure — Hydrostatic pressure is the pressure exerted by a liquid that depends on how deep it is.
  • immunohistochemistry — the application of immunologic techniques to the chemical analysis of cells and tissues.
  • imported currantworm — the larva of any of several insects, as a sawfly, Nematus ribesii (imported currantworm) which infests and feeds on the leaves and fruit of currants.
  • in bad circumstances — (of a person) in a bad financial situation
  • in case/just in case — If you do something in case or just in case a particular thing happens, you do it because that thing might happen.
  • in double-quick time — In double-quick time means the same as double-quick.
  • in the circumstances — a condition, detail, part, or attribute, with respect to time, place, manner,agent, etc., that accompanies, determines, or modifies a fact or event; a modifying or influencing factor: Do not judge his behavior without considering every circumstance.

  • industrial insurance — industrial life insurance.
  • infectious hepatitis — hepatitis A.
  • inferior conjunction — the alignment of an inferior planet between the sun and the earth.
  • instruction mnemonic — (programming)   A word or acronym used in assembly language to represent a binary machine instruction operation code. Different processors have different instruction sets and therefore use a different set of mnemonics to represent them. E.g. ADD, B (branch), BLT (branch if less than), SVC, MOVE, LDR (load register).
  • instruction prefetch — (architecture)   A technique which attempts to minimise the time a processor spends waiting for instructions to be fetched from memory. Instructions following the one currently being executed are loaded into a prefetch queue when the processor's external bus is otherwise idle. If the processor executes a branch instruction or receives an interrupt then the queue must be flushed and reloaded from the new address. Instruction prefetch is often combined with pipelining in an attempt to keep the pipeline busy. By 1995 most processors used prefetching, e.g. Motorola 680x0, Intel 80x86.
  • insulin-coma therapy — a former treatment for mental illness, especially schizophrenia, employing insulin-induced hypoglycemia as a method for producing convulsive seizures.
  • intermittent current — a direct current that is interrupted at intervals.

  • jack russell terrier — any of a breed of terrier with short hair and a mottled brown and white coat
  • james prescott joule — James Prescott, 1818–89, English physicist.
  • java virtual machine — (language, architecture)   (JVM) A specification for software which interprets Java programs that have been compiled into byte-codes, and usually stored in a ".class" file. The JVM instruction set is stack-oriented, with variable instruction length. Unlike some other instruction sets, the JVM's supports object-oriented programming directly by including instructions for object method invocation (similar to subroutine call in other instruction sets). The JVM itself is written in C and so can be ported to run on most platforms. It needs thread support and I/O (for dynamic class loading). The Java byte-code is independent of the platform. There are also some hardware implementations of the JVM.
  • job control language — a language used to construct statements that identify a particular job to be run and specify the job's requirements to the operating system under which it will run. Abbreviation: JCL.
  • joint life insurance — life insurance covering two or more persons, the benefits of which are paid after the first person dies.
  • jordan curve theorem — the theorem that the complement of a simple closed curve can be expressed as the union of two disjoint sets, each having as boundary the given curve.
  • joule-thomson effect — the change of temperature that a gas exhibits during a throttling process, shown by passing the gas through a small aperture or porous plug into a region of low pressure.
  • juno and the paycock — a play (1924) by Sean O'Casey.
  • justice of the peace — a local public officer, usually having jurisdiction to try and determine minor civil and criminal cases and to hold preliminary examinations of persons accused of more serious crimes, and having authority to administer oaths, solemnize marriages, etc.
