Everything, everyone, anything, and anyone is ingrained with a set of instructions to operate from the day it or they have come into existence. Otherwise without a set of purpose, there's really no point of that existence. As protocols are defined in the digital world as those instructions to exist or coexist, information can get passed on from one viewer to the next or a particular action can be executed on command. Without the idea of protocols or the implementation of them, the machine is just a machine standing idle like a paper weight waiting to be used, to have purpose.
