Similar to above example, if computers (or computer like devices) want to communicate each other, they must follow certain set of predefined communication rules. Here for communication between two parties (without the help of a translator), you must need a common language which both parties can understand and speak. If you try to speak to someone over the phone who can speak only Hindi language, the communication will miserably fail. Let us assume that you are a native English speaker and the only language you know is English. Network protocols define rules and conventions for communication between different devices, participating in a computer network.Ī simple real-world example is human communication. A network protocol can be viewed as a common network communication standard, which is used to define a method of exchanging data over a computer network.
