protocol
A set of formal rules describing how to transmit data, especially across a
network. Low level protocols define the electrical and physical standards to be
observed, bit- and byte-ordering and the transmission and error detection and
correction of the bit stream. High level protocols deal with the data
formatting, including the syntax of messages, the terminal to computer dialogue,
character sets, sequencing of messages etc.
Many protocols are defined by RFCs or by OSI.
