What is the difference between a judge and a lawyer in terms of their roles and responsibilities within the legal system?

A judge is a legal official who presides over court proceedings, makes decisions based on the law, and ensures fair trials. A lawyer, on the other hand, represents clients in legal matters, provides legal advice, and advocates on their behalf in court. Judges have the authority to interpret and apply the law, while lawyers advocate for their clients' interests within the legal system.
