In the world of communication, protocols made a big help to enable different devices such as cell phones, pc, IP phone and all other devices that is used for communication communicate with each other. All of these were possible because of this what we call protocol. So what is this protocol mean? It is a set of predetermined rules that is being followed by communicating devices. These devices used network protocol in communicating with each other. The concept of this protocol is like two people talking to each other, they should use one common language that both of them can understand. Also if one person is talking the other one should listen and vice versa. Lastly tell the person you are talking too that you have already finished talking. This process of communicating has been a standard in all kinds of conversation. This is the same way with devices communicating with each other, they follow protocol that has been approved by the networking industry and ratified by a standards organization.
