The first difference is that while conduct can be either a noun or a verb, behavior occurs as a noun, in this word form. Behavior refers to the action of a living being or a system, while conduct, as a noun refer to the way a person acts, especially from the point of view of morality and ethics. As a verb, it can mean lead or control, or to serve for conveying or transmitting. Behavior can mean the response to various external impulsions and it is controlled by the nervous system. In musical sense, conduct refers to the act of direction of a performance. To put it differently, behavior is regarded as any action of a person or a system that changes its relationship towards the environment. Conduct is different, it is about controlling and leading or how a person acts from the viewpoint of morality.
