Ethics and morals are two similar terms with a thin line difference between them. Ethics is more or less like a code of conduct that is laid down by a society or a cultural group. These include national ethics, professional ethics, company ethics, social ethics, or family ethics.
Ethics can be adjusted, and there is a requirement for you to update yourself as the ethics are being changed because their might most likely be one or more consequences for violating an ethical standard. Ethics can, however, be against your morals, but you still have to adhere.
Morals, on the other hand, are more of a personal thing or etiquette. Morals are not really sets of rules to follow, but more of a personal belief or faith. A thing you accepted to be right with you can be entirely wrong with someone else. However, you are not bound to follow your morals, though, and no punishment for that.
