Protocol is defined as etiquette of formal occasions: the rules or conventions of correct behavior on official or ceremonial occasions or code of conduct: the rules of correct or appropriate behavior of a group, organization or profession.
Other procedures involve practicality, courtesy and common business practice--when speaking at a meeting, stand so that others can see who is speaking; use the microphone if it is available so everyone can hear what you have to say; wait to be recognized/acknowledged by the president before speaking to a motion; pay for your meals and pay your dues on time.
