Culture is defined as the learned behaviors, values, and beliefs shared by a society. It encompasses symbols, heroes, rituals, values, norms, and expressions. Hofstede's model identifies key dimensions of culture including power distance, uncertainty avoidance, individualism vs collectivism, masculinity vs femininity, and long vs short-term orientation. While useful for business, Hofstede's model has limitations and culture is complex with intracultural differences existing within societies. Understanding cultural distance is important for international business.
