USS Enterprise computer core, late 2260s.
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 Starfleet ships had duotronic systems, while 24th century ships had isolinear cores. The computer cores communicate with each other and ship's systems via optical data network (ODN).
Galaxy-class computer access room and core c.2360s.
The Template:ShipClass of Federation starships carry three computer cores, while ships of the Intrepid- and Template:ShipClasses contain two. These multiple cores provide redundancy in case one of the cores should be damaged or destroyed.
The computer core could be accessed by the computer access room. (TNG: "Evolution")

In order to take Deep Space 9's computer systems offline and prevent the Dominion from destroying the minefield covering the Bajoran wormhole, Kira Nerys and Rom considered planting a bomb in the station's computer core. They later attempted to sabotage it by more standard means. (DS9: "Sacrifice of Angels")
