Some what: when R2 interfaces with a computer node his on board software sends communication cmd code strings to the network he is interfacing with and vice versa: Its like plugging your computer into the internet or a lan network and then sending a text or chat message. Your computer's Operating System never leaves your terminal node (pc) but allows you to communicate with the network and vice versa. And like your computer's OS and the fire wall protecting your computer from un authorized attacks or communications from the network; Droids have a semi physical separation from their main functional AI OS and the software they use to communicate with computer network interfaces.
