Text-based protocol
Appearance
A text-based protocol or plain text protocol is a communications protocol whose content representation is in human-readable format.
The immediate human readability stands in contrast to binary protocols which have inherent benefits for use in a computer environment (such as ease of mechanical parsing and improved bandwidth utilization).
Text-based protocols are typically optimized for human parsing and interpretation, and are therefore suitable whenever human inspection of protocol contents is required, such as during debugging and during early protocol development design phases.
