A code of ethics is a set of principles and rules used by individuals and organizations to govern their decision making process, as well as to distinguish right from wrong. These codes are often more complex and contextual than simple morality, acknowledging specific situations and providing guidance. Many codes of ethics also specify penalties for violations.
