For a person to be classified as bilingual, the person has to live as a child in an environment that is bilingual in terms of the language exchange pattern, for instance, a child raised by parents of different languages. Multilinguals, on the other hand, acquired other languages through learning the language or by cultural experience through interaction and exchange.
Bilingualism and multilinguaism are two distinctive forms of how the foreign language was acquired.
