The computer core is the location of a starship's or space station's central computer.
The computer core houses primary processing equipment. 23rd century ships had duotronic systems, with 24th century ships having isolinear cores. The computer cores communicate with each other and ship's systems via optical data network (ODN). At least since the beginning of 24th century the computer cores have a non-propulsive subspace field, making faster-than-light processing possible.
The Galaxy class of Federation starships carry three computer cores, whilst ships of Intrepid and Sovereign class contain two.
