  • The material at the center of an electromechanical relay or solenoid, about which the coil is wound.
• Computers:
  • 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.
