USB comes with a large vocabulary of its own: version numbers, marketing names, connector names, abbreviations for charging technologies, and terms borrowed from storage and security. This glossary collects that vocabulary from A to Z in one place, with a short, plain explanation for each term and a link to the full entry.
Use it whenever you come across an unfamiliar word on this site or on a product listing elsewhere, such as e-marker, Alternate Mode, PPS or UASP. Each entry also links back to the overview page or guide where that term is explained in more practical depth, so the glossary works well both as a quick lookup and as a starting point for exploring a topic further.
