The main difference between Judge and Prosecutor is that the Judge is a official who presides over court proceedings and Prosecutor is a supreme representative of the prosecution (of the state)
A judge is a person who presides over court proceedings, either alone or as a part of a panel of judges. The powers, functions, method of appointment, discipline, and training of judges vary widely across different jurisdictions. The judge is supposed to conduct the trial impartially and, typically, in an open court. The judge hears all the witnesses and any other evidence presented by the barristers of the case, assesses the credibility and arguments of the parties, and then issues a ruling on the matter at hand based on his or her interpretation of the law and his or her own personal judgment. In some jurisdictions, the judge’s powers may be shared with a jury. In inquisitorial systems of criminal investigation, a judge might also be an examining magistrate.
The prosecutor is the chief legal representative of the prosecution in countries with either the common law adversarial system, or the civil law inquisitorial system. The prosecution is the legal party responsible for presenting the case in a criminal trial against an individual accused of breaking the law. Typically, the prosecutor represents the government in the case brought against the accused person.
