I worked on FAA systems for a while, mostly FDIO (Fight Data Input Output, aggravatingly pronounced Fido by controllers), where we couldn't even just refer to a monitor and keyboard as such, had to go and call them a RANK (Replaceable Alpha Numeric Keyboard) and CRT (in spite of them long since having moved away from Cathode Ray Tube technology)
Ha, I am not a controller but I have always called FDIO "Fido". Never heard of RANK or CRT though, probably to be expected since there are so many different systems in the NAS, each with its own unique terminology.
