1. (computer science) a tiny ferrite toroid formerly used in a random access memory to store one bit of data;
   Now superseded by semiconductor memories (synset 103112720)
   "each core has three wires passing through it, providing the means to select and detect the contents of each bit"

   is a type of: toroid, torus - a ring-shaped surface generated by rotating a circle around an axis that does not intersect the circle
   is a part of:

   • core memory, magnetic core memory - (computer science) a computer memory consisting of an array of magnetic cores; now superseded by semiconductor memories
   • ram, random access memory, random memory, random-access memory, read/write memory - the most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible
