Diachronic linguistics is the study of a language through the course of its history. A synchronic description takes a fixed instant (usually, but not necessarily, the present) as its point of observation. Most grammars are of this kind.
Langue & parole
Langue is abstract, parole specific to the speaking situation; langue not actually spoken by an individual, parole always a naturally occurring event; langue relatively stable and systematic, parole subject to personal and situational constraints.
Competence & performance
