- 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:
- 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. The term is a legacy from systems which used core memory.
- 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 more dense 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.
