A protocol is a set of rules describing some behavior. In order to communicate in a common manner, the sender and receiver have to agree on the "language" of communication.

A protocol states what those rules are, and because they are a standard, everyone agrees and knows what to expect.

Protocols r used for network devices to communicate to each other. For e.g if one device on a network needs IP address, it'll use respective protocols for that. For sending data over some media, protocols are used. For setting up the speed, protocols are required. For security, protocols are there.

Network is a world quite different form our human world. For what purpose we use our language, network devices use protocols for that.
