PROTOCOL

When you study in a university or work in an organization, you are subjected to certain dos and don'ts that you need to follow like Reaching on time, wearing formals and submitting assignments within the given deadline. The word protocol basically means a set of rules and guidelines that are needed to be followed by people.

It refers to an appropriate behaviour and rules of conduct for a particular situation or an event. So when you follow your office etiquettes, it means you are following the protocol. It could also mean a formal agreement between two parties. A protocol guides you how an activity should be performed especially in the field of diplomacy.

For example, a President of one country visiting another country is to be received by a person in a similar position and status in the host country. This is a kind of protocol and should not be violated. In the field of technology, a standard method for connecting computers for an exchange of data among them is also a protocol. As the word protocol is a kind of 'set of rules', it is a noun.
