- network interface card — network interface controller
- network node interface — (networking) (NNI) The ATM Forum's specification for connections between network nodes. NNI makes network routing possible. It typically refers to backbone trunk connections between ATM switching equipment. See also: UNI.
- nickel-cadmium battery — a storage battery, with an alkaline electrolyte, having nickel oxide as the positive element and cadmium as the negative.
- nitrohydrochloric acid — aqua regia.

- nominal semidestructor — (abuse) Slang for "National Semiconductor", found among other places in the 4.3BSD networking sources. During the late 1970s to mid-1980s this company marketed a series of microprocessors including the National Semiconductor 16000 and National Semiconductor 32000. At one point early in the great microprocessor race, the specs on these chips made them look like serious competition for the rising Intel 80x86 and Motorola 680x0 series. Unfortunately, the actual parts were notoriously flaky and never implemented the full instruction set promised in their literature, apparently because the company couldn't get any of the mask steppings to work as designed. They eventually sank without trace, joining the Zilog Z8000 and a few even more obscure also-rans in the graveyard of forgotten microprocessors.
- non-euclidean geometry — geometry based upon one or more postulates that differ from those of Euclid, especially from the postulate that only one line may be drawn through a given point parallel to a given line.
- nonterminating decimal — a decimal numeral that does not end in an infinite sequence of zeros (contrasted with terminating decimal).
- normal order reduction — Under this evaluation strategy an expression is evaluated by reducing the leftmost outermost redex first. This method will terminate for any expression for which termination is possible, whereas applicative order reduction may not. This method is equivalent to passing arguments unevaluated because arguments are initially to the right of functions applied to them. See also computational adequacy theorem.

- planck's radiation law — the law that energy associated with electromagnetic radiation, as light, is composed of discrete quanta of energy, each quantum equal to Planck's constant times the corresponding frequency of the radiation: the fundamental law of quantum mechanics.
- plastic pin grid array — (hardware, processor) (PPGA) The package used for certain Intel Celeron processors. PPGA processors fit into Socket 370 motherboard sockets. The Plastic Pin Grid Array packaging is similar to that used on Pentium processors. The silicon core is covered by a heat slug that faces down toward the motherboard. The Celeron 300A to the 533 use a PPGA package. The Celeron 566 onward use a FC-PGA package. Celeron processors are also available in Slot 1 SEPP packaging.
