Question

what are known as buzzwords

Answer 1

A buzzword is a term or phrase that becomes very popular in some specific context. Buzzwords are typically either newly coined words -- often acronyms or portmanteaus -- or existing terms used in a different way than they were in the past. Sometimes a buzzword is a new term for a popular new technology or concept.
