Culture is defined as the total way of life shared by members of a community, including both nonmaterial aspects like language and values as well as material objects. There are two main categories of culture: nonmaterial culture such as language, values, and meanings, and material culture consisting of physical objects produced by a society. Common assumptions about culture are that it is a problem-solving mechanism, it is relative to each individual culture, and it is a social product learned and changed by people over time. Culture is transmitted through carriers such as language, values, and norms.
