What is the full name of amp?

Excuse me, could you please clarify what you mean by "amp"? Is it referring to a specific cryptocurrency, a technical term, or something else entirely? If we're talking about a cryptocurrency, there are a few tokens that use "AMP" as part of their name, such as Flexa Capacity Token (AMP). However, without further context, I'm unable to provide the full name definitively. Could you elaborate on the context in which "amp" is being used?
