Core

• In archaeology, a core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more lithic flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone.
• In astrophysics, the core of a star is its center where nuclear fusion takes place. In astrophysics and geology, a planetary core is the composite material at the centre of a planet.
• In biology, the core of a fruit contains its seeds.
• In computing:
• Core memory or storage is memory made of magnetic toruses.
• Core nowadays usually means primary storage regardless of hardware technology (typically semiconductor random access memory).
• A core dump is a record of the contents of primary storage.
• In Unix and Unix-like operating systems, core is a file that contains a memory dump -- known as a core dump -- of a computer program that has crashed for some reason. It is used for debugging purposes.
• Hardware description language (HDL) modules, when distributed, are called "cores" (see open hardware).
• In construction, when the force in an element is within a certain center section, the core, the element will only be under compression.
• In economics, the core is a feasible allocation in an economy that cannot be improved upon by any coalition of consumers.
• In mathematics, the core of a group is an object appearing in group theory.
• In a nuclear reactor, the core is the portion containing the fuel components.
• In planetary science, the core of a planet contains its innermost layer(s). Due to planetary differentiation, such layers tend to be denser than outer layers.
• In telecommunication:
• The central region about the longitudinal axis of an optical fiber, which region supports guiding of the optical signal.
• A piece of ferromagnetic material, usually toroidal in shape, used as a component in a computer core memory device or transformers.
• The material at the center of an electromechanical relay or solenoid, about which the coil is wound.
• In injection moulding, the core is the solid part of the mould that helps shape the plastic material injected.
