Isolinear core
An isolinear core was a removable computer core on  starships. The ship had many such cores arranged in banks of two; each one was responsible for a particular system function, such as regulating auto-repair for the shield array. The banks themselves in which the cores where inserted into were also removable.

In 2380, Ensigns Beckett Mariner, Brad Boimler, and  were assigned to replace the chips in the ' isolinear cores. Fletcher volunteered to complete the task alone so that Mariner and Boimler could attend the Chu Chu dance, but he soon found the work too difficult and so sought to increase his intelligence by connecting his brain directly to one of the cores. However, his brain waves instead corrupted the core, causing it to become animate and attempt to make itself "smarter", as Fletcher had, by incorporating nearby technology into itself. Mariner and Boimler managed to drag the core to an airlock and eject it into space, whereupon it drifted into and disabled a hostile Drookmani ship. Afterwards, they claimed that Fletcher had deliberately weaponized the core, so as to earn him a transfer off the Cerritos and they would no longer have to deal with his behavior. ()
