Protocols are rules that govern how communication takes place in networks. Without this rules communication will be more difficult. Protocols help format the message, define the way devices share information, and how to terminate and initiate communications. The organizations that create networking protocols are [|Internet Engineering Task Force (IETF)] and the [|Institute of Electrical and Electronics Engineers (IEEE)].
