[Middle English.]

(1) The heart, or central part, of something. The core of a network is its backbone. A core program would be the primary routines that serve the entire application (see kernel).

(2) In digital electronics, it typically refers to a relatively large, general-purpose logic function that is used as a building block in a chip design. Examples are microprocessor, microcontroller and DSP cores. Cores may be developed internally, but are generally purchased from third-party intellectual property (IP) vendors. See soft core and hard core.

(3) A CPU. A microprocessor with two cores (dual cores) is a single chip that contains two processors. See dual core and multicore.

(4) (Core) A family of CPU chips from Intel. Introduced in 2006, the Core line was developed to supersede the Pentium brand. See Intel Core.

(5) A round magnetic doughnut that represents one bit in an earlier core storage system. When core storage was common in the 1960s, a computer's main memory used to be called "core." See core storage.

n. The center of a fruit such as an apple, pear or pineapple. Cores may contain small seeds, or they may be tough and woody, or both. core v. To remove the core from a fruit.

noun

1. A point of origin from which ideas or influences, for example, originate: bottom, center, focus, heart, hub, quick, root. See start/end.
2. The most central and material part: essence, gist, heart, kernel, marrow, meat, nub, pith, quintessence, root, soul, spirit, stuff, substance. Law gravamen. See be.

n

Definition: center, gist
Antonyms: covering, exterior, exteriority, outside, perimeter, surface

Main storage or RAM. Dates from the days of ferrite-core memory; now archaic as techspeak most places outside IBM, but also still used in the Unix community and by old-time hackers or those who would sound like them. Some derived idioms are quite current; in core, for example, means ‘in memory’ (as opposed to ‘on disk’), and both core dump and the core image or core file produced by one are terms in favor. Some varieties of Commonwealth hackish prefer store.

n

The central part. A section of a mold, usually of plaster, made over assembled parts of a dental restoration or construction to record and maintain the relationships of the parts so that the parts can be reassembled in their original positions. Synonym: laboratory core.

1. The central part of the earth. The inner core has the properties of a solid and the outer core those of a liquid. The core is dense, very hot, and probably composed largely of iron and nickel.

2. The centre of the core-periphery model.

1. The center of a plywood or crossbanded construction; it may consist of lumber (solid or glued) or particleboard; serves as a base for veneer.
2. The internal structure in a hollow-core door.
3. The wood chips cut from a mortise.
4. The metal bar to which a handrail is attached.
5. The internal structure which serves as a base for complex plasterwork.
6. The molded open space in a concrete masonry unit.
7. The filling within a thick hollow stone wall.
8. The filling between a lintel and relieving arches.
9. A cylindrical sample of hardened concrete or rock obtained by means of a core barrel and drill. 10. A part of a multistory building, containing a variety of service and utility functions, as elevators, stairwells, etc. 11. That part of a magnetic circuit (usually steel or iron laminations) about which are wound coils in electromagnetic devices such as transformers, solenoids, relays, etc.; a magnetic core. 12. (Brit.) The conductor of a cable with its insulation, but not including any outer protective covering. 13. That portion of a grille, 2 contained within the frame. 14. Of gypsum board, the hardened material filling the space between a face paper and a back paper; consists primarily of gypsum with additives. 15. (British) Same as blockout.

[Ar]

1. The piece of stone which a stone-knapper works so as to produce flakes, blades, or core tools.

2. [Ge]. An intact solid cylinder-shaped sample of sediment, stone, or wood collected with a coring device or hollow drill. Deep-sea cores and ice cores provide important records of climatic change and sediment accumulation. Cores taken from archaeological sites provide a quick guide to the main stratigraphic subdivisions. Cores from peat bogs can be sampled for pollen analysis. Cores taken from substantial timbers are used in dendrochronology.

In geology, the central region of the Earth; it extends fourteen hundred to eighteen hundred miles from the Earth's center.

The core is made primarily of iron and nickel and has two parts — an inner solid core and an outer liquid core.

The mantle is the layer of the Earth that overlies the core.

Magnetic material within a coil used to concentrate the magnetic field.

The central region of a planet or moon frequently made of denser materials than the surrounding regions (mantle and crust). Earth and the Moon are thought to have cores of iron and nickel.

The innermost portion of plywood usually composed of veneer. Also referred to as a "centre." A core may also be made of fibreboards, particleboard or lumber.

IN BRIEF: n. - A bar of magnetic material (as soft iron) that passes through a coil and serves to increase the inductance of the coil; The chamber of a nuclear reactor containing the fissile material where the reaction takes place;

Tutor's tip: Some people think the Marine "Corps" (a large or specialized military unit) is the "core" (the center or mainstay of any organization or system) of our armed forces.
