The "brain" of K.I.T.T. was the Knight 2000 Microprocessor, the center of a "self-aware" cybernetic logic module that allowed K.I.T.T. to think, learn, communicate and interact with humans. K.I.T.T. was given a sensitive personality that included an easily brusied ego. Although the belief that K.I.T.T. was truly sentient was never discussed on the show, K.I.T.T. was fully aware of himself.
