Culture is the characteristics and knowledge of a particular group of people, defined by everything from language, religion, cuisine, social habits, music and arts.
Culture is defined as all the products of society-- material and nonmaterial; Society consists of interacting people living in the same territory who share a common culture. We really can't have one without the other (unless you want to call archaeological remains and historical records culture).
