Pilot - The process of testing a part of the final system as a gauge to determine the viability of the concept prior to implementing the entire system for full production. It takes the concept out of the realm of theory, and provides empirical knowledge of what can reasonably be expected of the system when it is fully implemented. Usually, such a system is interactive. Simple protocols define only hardware configuration.
More complex protocols define timing, data formats, error detection, and correction techniques.
Protocol Conversion - For computers with different protocols to understand each other meaningful conversation needs to take place. Many VANS are equipped to allow conversations between different 'tongues'. Any switching communications system such as Telex, TWX or public telephone networks - that provide circuit switching to many customers. For example, purchase order, purchase order change, purchase order acknowledgment.
