A nut is a type of fastener with a threaded hole. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: Adhesives, safety pins or lockwire, nylon inserts, or slightly oval-shaped threads. The most common shape is hexagonal, for similar reasons as the bolt head - 6 sides give a good granularity of angles for a tool to approach from (good in tight spots), but more (and smaller) corners would be vulnerable to being rounded off. It takes only 1/6th of a rotation to obtain the next side of the hexagon and grip is optimal. However polygons with more than 6 sides do not give the requisite grip and polygons with less than 6 sides take more time to be given a complete rotation.Other specialized shapes exist for certain needs, such as wing nuts for finger adjustment and captive nuts for inaccessible areas.
Hardware may refer to:
Computer Hardware (usually simply called 'hardware' when a computing context is concerned) is the collection of physical elements that constitutes a computer system. Computer hardware is the physical parts or components of a computer, such as the monitor, mouse, keyboard, computer data storage, hard disk drive (HDD), graphic cards, sound cards, memory (RAM), motherboard, and so on, all of which are physical objects that are tangible. In contrast, software is instructions that can be stored and run by hardware.
Software is any set of machine-readable instructions that directs a computer's processor to perform specific operations. A combination of hardware and software forms a usable computing system.
The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.
In development cooperation jargon, "hardware" and "software" refer to the different aspects of technology transfer. Whilst the hardware refers to the technology itself, software refers to the skills, knowledge and capacity that need to be built up in order to make the transfer of the technology successful.
A third term, "orgware", is emerging to refer to the capacity building of the different institutional actors involved in the adaptation process of a new technology.
Nut, NUT, Nuts or NUTS may refer to:
A nut is a fruit composed of a hard shell and a seed, which is generally edible. In a general context, however, a wide variety of dried seeds are called nuts, but in a botanical context, there is an additional requirement that the shell does not open to release the seed (indehiscent). The translation of "nut" in certain languages frequently requires paraphrases, as the word is ambiguous.
Most seeds come from fruits that naturally free themselves from the shell, unlike nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts, such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut.
A nut in botany is a simple dry fruit with one seed (rarely two) in which the ovary wall becomes very hard (stony or woody) at maturity, and where the seed remains unattached or free within the ovary wall. Most nuts come from the pistils with inferior ovaries (see flower) and all are indehiscent (not opening at maturity). True nuts are produced, for example, by some plant families of the order Fagales.
N'Gabthoth is a demon who has clashed with the Doctor Strange. He once served as an agent of Shuma-Gorath. N'Gabthoth has great magical power, and could fire bolts of mystical force from his eye.
The Nameless One is a two-headed demon. The Nameless One first appeared in Sub-Mariner #22 (February 1970), and was created by Roy Thomas and Marie Severin. He was the leader of the Undying Ones, and led them to conquer the Earth millennia ago. The Undying Ones ruled the Earth for ages, though eventually their powers waned and were forced to return to their own realm. The Nameless One continued to rule them when they were exiled from Earth, and during several attempts to conquer it again in modern times. Later, another demon became a successor to the previous, two-headed Nameless One as leader of the Undying Ones. This demon tried to use Wolverine to kill Doctor Strange. Wolverine, enhanced by demonic magic, slew this Nameless One and many of the Undying Ones.
