Foremost, probation describes the sentence given by the judge, either in portion or as a whole. Sometimes, when someone commits a minor crime, he can be put on probation to serve as punishment for him. If you are on probation, you will need to be attending to some sessions with a probation officer.
You can be put on curfew, and you will also not be permitted to drive. If you are caught committing another crime again, you would be put in jail to serve more years there. On the other hand, parole is given to a prisoner by the parole board. Sometimes, the judge sentences these kinds of people for the crime they have committed. If a prisoner has been found to be peaceful in prison, he can be given parole, which most likely shortens his year in prison. If you are on parole, you still have some expectations you are to meet up with. You are to be in contact with your parole officer regularly, and also inform him should in case you are leaving the country.
