Probation is a prison sentence that is suspended on the condition that the offender follow certain prescribed rules and commit no further crimes. Today, probation is a federal, state, and local activity administered by more than 2,000 separate agenices, with nearly 4 million adult offenders under supervision. (Seiter 2014)
Parole, both a procedure by which a board administratively releases inmates from prison as well as a provision for post-release supervision, comes from the French word parol, referring to "word," as in giving one's word of honor or promise.
