• A protocol is a set of rules for formatting and processing data in networking. Computer protocols are similar to a common language. Although the software and hardware used by the computers in a network may differ greatly, protocols allow them to communicate with one another.
• Standardized protocols are analogous to how two people from different parts of the world may not speak each other's original languages but can communicate through a shared third language.
• If one computer and another computer both utilise the Internet Protocol (IP), they will be able to communicate — much as the United Nations uses its six official languages to speak with delegates from all over the world. However, if one computer uses IP and the other does not, they will not be able to interact.
