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.
According to Episode 55, "Dead of Knight", K.I.T.T.'s reaction time is one nanosecond, and his memory capacity is 1,000 megabits. For the latter, it is uncertain whether or not active RAM or hard drive space was being discussed. According to Episode 65, "Ten Wheel Trouble", KITT's future capacity is unlimited.
- K.I.T.T. was programmed to obey all orders given to him by his human creators, so long as they didn't violate his prime directive of protecting human life (especially Michael's) to the best of his abilities.
- The system could drive the car better than a human operator could.
- He could provide music, video and video games via an in-dash entertainment system.
