Computer

Modern day computers are kiwis disguised to look computer like by the Founders so as to lull Starfleet into a false sense of security.
This is known to be 100% fact despite the complete and total lack of evidence. Since you cannot prove that it isn't a kiwi, despite looking and functioning exactly like a computer should and does, it is in fact a kiwi.
In addition, many believe that any computer that does not precisely match the configuration of the ENIAC is not actually a computer. The Founders are also believed to be behind any and all computers that are any different than the ENIAC.
