A protocol is a shared set of expectations that allow two or more things to communicate. It says “I will announce myself in this way” and “these are the responses you should expect to this request” and “here’s the list of all the things I know how to do”, and if we both follow the protocol, then we both understand what’s going to happen when we communicate.
