Protocol

A protocol is a set of formalized rules describing how to transmit data across a network, or within a computer. A software implementation is known as a protocol stack.

Description

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 dialog, character encoding, and sequencing of messages.
