Network Communication Speed Comparison Chart
As the demand for faster speeds has grown rapidly over recent decades, new communications networking equipment and systems are constantly being developed to accommodate these requirements . A result of these efforts is a series of established networking protocols and terminology that are used to identify various speed thresholds and the related equipment.
The chart below is intended as a quick reference guide to help readers associate the various networking speeds with their respective protocol/service names.
