Data-font

The data-font glows when activated.

A data-font is a form of optical computer interface used by Cylons to access information in their datastream, as well as control various other Cylon technologies. Humanoid Cylons need only to place their palm on the port to instantly access the data stream (Exodus, Part I).

Caprica-Valerii performs a rough version of this technique with Colonial technology by inserting a fiber optic cable (which uses light as a data carrier) into an incision in her left arm to connect to Galactica's computer mainframe (Flight of the Phoenix). Another Eight interfaces with a Raptor's computer in the same manner (The Face of the Enemy).

Data-fonts are found on basestars in the ship's command and control center for data access and other ship functions. These data ports have a layer of water over the interface, which may have an aesthetic or functional purpose. These data-fonts (and the database circuitry used throughout the ship) are apparently organic in design, as they are damaged after an infection kills or shuts down almost every Cylon entity and device on the basestar (A Measure of Salvation).

Models can only access information to which they are privy to, e.g. Eights can not learn anything meant for the Sixes only.

Notes

• The term "data-font" comes from Ron D. Moore, who calls these devices as this in a forum post on SCIFI.com . It is also used by the Hybrid in the episode "Six of One".
• While the humanoid's spines and eyes have been seen to glow, the writers have noted that the spine glow was an early cinematic effect that was disused after season 1.
• The Mirriam-Webster definition of font (aside from its modern usage as an element of a printed typeface) is a receptacle for baptismal water, such as those touched by members of the Roman Catholic church as they arrive and leave Mass.
