- crystal microphone — a microphone that uses a piezoelectric crystal to convert sound energy into electrical energy

- data flow analysis — (programming) A process to discover the dependencies between different data items manipulated by a program. The order of execution in a data driven language is determined solely by the data dependencies. For example, given the equations 1. X = A + B 2. B = 2 + 2 3. A = 3 + 4 a data-flow analysis would find that 2 and 3 must be evaluated before 1. Since there are no data dependencies between 2 and 3, they may be evaluated in any order, including in parallel. This technique is implemented in hardware in some pipelined processors with multiple functional units. It allows instructions to be executed as soon as their inputs are available, independent of the original program order.
- development system — a computer system, including hardware and software, that is specifically designed to aid in the development of software and interfaces
- didot point system — a Continental system of measurement for type, based on a unit of 0.0148 inches (0.3759 mm).

- discourse analysis — the study of the rules or patterns characterizing units of connected speech or writing longer than a sentence.
- distributed system — A collection of (probably heterogeneous) automata whose distribution is transparent to the user so that the system appears as one local machine. This is in contrast to a network, where the user is aware that there are several machines, and their location, storage replication, load balancing and functionality is not transparent. Distributed systems usually use some kind of client-server organisation. Distributed systems are considered by some to be the "next wave" of computing.
- domain name system — (networking) (DNS) A general-purpose distributed, replicated, data query service chiefly used on Internet for translating hostnames into Internet addresses. Also, the style of hostname used on the Internet, though such a name is properly called a fully qualified domain name. DNS can be configured to use a sequence of name servers, based on the domains in the name being looked for, until a match is found. The name resolution client (e.g. Unix's gethostbyname() library function) can be configured to search for host information in the following order: first in the local hosts file, second in NIS and third in DNS. This sequencing of Naming Services is sometimes called "name service switching". Under Solaris is configured in the file /etc/nsswitch.conf. DNS can be queried interactively using the command nslookup. It is defined in STD 13, RFC 1034, RFC 1035, RFC 1591.

- honeysuckle family — the plant family Caprifoliaceae, typified by shrubs and woody vines having opposite leaves, clusters of usually flaring, narrow, tubular flowers, and various types of fruit, and including the elder, honeysuckle, snowberry, twinflower, and viburnum.
- hypophysis cerebri — the master endocrine gland, attached by a stalk to the base of the brain.
- hysterical reasons — (Or "hysterical raisins") A variant on the stock phrase "for historical reasons", indicating specifically that something must be done in some stupid way for backward compatibility, and moreover that the feature it must be compatible with was the result of a bad design in the first place. "All IBM PC video adaptors have to support MDA text mode for hysterical reasons." Compare bug-for-bug compatible.
- information system — a computer system or set of components for collecting, creating, storing, processing, and distributing information, typically including hardware and software, system users, and the data itself: the use of information systems to solve business problems.
- interface analysis — (testing) A software test which checks the interfaces between program elements for consistency and adherence to predefined rules or axioms.
- investment analyst — a specialist in forecasting the prices of stocks and shares

- neurophysiological — the branch of physiology dealing with the functions of the nervous system.
- new storage system — (storage) (NSS) A major Multics implementation project during the 1970s. The initial Multics file system design had evolved from the one-huge-disk world of CTSS. When multiple disk units were used they were just assigned increasing ranges of disk addresses, so a segment could have pages scattered over all disks on the system. This provided good I/O parallelism but made crash recovery expensive. NSS redesigned the lower levels of the file system, introducing the concepts of logical volume and physical volume and a mapping from a Multics directory branch to a VTOC entry for each file. The new system had much better recovery performance in exchange for a small space and performance cost.
- numerical analysis — the branch of mathematics dealing with methods for obtaining approximate numerical solutions of mathematical problems.
- ovariohysterectomy — Surgical removal of the ovaries and uterus.
- phanerocrystalline — (of a rock) having the principal constituents in the form of crystals visible to the naked eye.
- physical chemistry — the branch of chemistry dealing with the relations between the physical properties of substances and their chemical composition and transformations.
- physical education — systematic instruction in sports, exercises, and hygiene given as part of a school or college program.
- physical geography — the branch of geography concerned with natural features and phenomena of the earth's surface, as landforms, drainage features, climates, soils, and vegetation.
