Binary

"We droids think in binary. One and zero, on and off, yes and no. This gives us clarity, makes us happy. Things are either real or not real, known or not known. A thinking individual is either an organic or a droid. Simple, right?"

- Zeta the construction droid

Binary or droidspeak was the language commonly spoken by droids. It consisted of a set of beeps and whistles strung together into what resembled sentences. The C1-series astromech droid utilized this form of communication, as did Industrial Automaton's R2 series astromech droid. While difficult, some organics such as Anakin Skywalker, Hera Syndulla and Rey were able to understand it. After many years, Luke Skywalker was also able to understand binary which he didn't when he was younger as a farm boy.

The most common way for binary droids to communicate with organics was by writing, conveyed via another computer system. This is how astromech droid copilots would speak with the pilot of a starfighter.

All droids could understand binary. Without a computer system to write their words when it was necessary for organics to hear what a binary-only droid had to say, another droid, such as protocol droids or others capable of speaking a common language like Galactic Basic could translate for them. The astromech BB-8 spoke in 27th generation droidspeak, a compressed variant of standard droidspeak.

Binary was also used as a programming language for devices that did not have the artificial intelligence of droids, such as binary loadlifters and moisture vaporators.
