Core or cores may refer to:

Science and technology

• Core (anatomy), everything except the appendages →appendix
• Core (manufacturing), used in casting and molding
• Core (optical fiber), the signal-carrying portion of an optical fiber
• Core, the central part of a fruit
• Hydrophobic core [疏水核], the interior zone of a protein →phobia
• Nuclear reactor core, a portion containing the fuel components
• Pit (nuclear weapon) or core, the fissile [裂变] material in a nuclear weapon →fusion
• Semiconductor intellectual property core (IP core), is a unit of design in ASIC/FPGA electronics and IC manufacturing
  • ASIC stands for Application Specific Integrated Circuit. It is a piece of hardware that is designed specifically for a specific purpose.
  • Field Programmable Gate Arrays (FPGAs) are semiconductor devices that are based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnects. FPGAs can be reprogrammed to desired application or functionality requirements after manufacturing.
• Atomic core, an atom with no valence electrons 原子核，没有价电子的原子

Geology and astrophysics [天体物理学 astro+physics] →astronaut, asteroid, asterisk

• Core sample, in Earth science, a sample obtained by coring
• Ice core
• Core, the central part of a galaxy
• Planetary core, the center of a planet; Earth's inner core; Earth's outer core; Solar core, the region of the Sun where nuclear fusion takes place

Computing

• Magnetic core, in electricity and electronics, ferromagnetic material around which wires are wound
  • An Wang [王安] was a prominent Chinese-American computer engineer and inventor who invented the magnetic pulse transfer controlling device. This device made magnetic core memory possible in the development of computers.
  • Magnetic-core memory, the primary memory technology used before semiconductor memory
  • Core dump, the recorded state of a running program
• Central processing unit (CPU), called a core
  • Multi-core processor, a microprocessor with multiple CPUs on one integrated circuit chip
• Core Animation, a data visualization API used in macOS
• Intel Core, a family of single-core and multi-core 32-bit and 64-bit CPUs released by Intel
• Server Core, a minimalist Microsoft Windows Server installation option

Mathematics

• Core (graph theory), the homomorphically minimal subgraph of a graph →homogeneous, heterogeneous, morph, morpheme, morphology
• Core, a radial kernel of a subset of a vector space 核、值域、向量空间、行空间、零空间

Other uses

• Core countries, in dependency theory, an industrialized country on which peripheral countries depend
• Core curriculum, in education, an essential part of the curriculum →curriculum vitae (cv)
