Computer Core A star ship's computer core controls every system onboard the ship, from weapons to propulsion. All Federation starships feature multiple redundant computer cores. Each core is capable of running all of the ship's primary systems and most of the secondary systems. On larger ships like the Galaxy and Sovereign classes two primary cores are located in the saucer section, these cores run in parallel to each other, if one fails the other core is able to take over with missing a calculation. A third core is located in the star drive section and is used only when the two primary cores fail or when the saucer is separated. The computer cores are massive cylindrical objects that that cross seven decks, on smaller ship like the Defiant class the cores are only two decks high. The computer core uses Faster Then Light data transfer, this is accomplished by using miniature subspace field generators. The upper level of the core contains the core monitoring room, the FTL nano-processor units, and access to the subspace field system. Each core on a Galaxy class ship has 2,048 modules made up of 144 Isolinear chips that provide a storage capacity of 630,000 kilo quads with a memory access rate of 4,600 kilo quads/sec. The main cores are supplemented by 380 sub processors located throughout the ship. These sub processors do not have FLT capabilities but help to improve overall response time of the system. The main cores and the sub processors are both tied into the ships Optical Data Network All of the ships display panels, sensors, relpicator, and system are connected to the ships ODN system for direct access to the computer core or sub processor
