What do you mean by goods and services in a National income explain me goods and services i need handwritten explanation plz

Dear Student, National income is the total market value (in monetary terms) of all final goods and services produced by the firms during an accounting year. Final goods refer to those goods and services that are meant for final consumption by the consumers. In other words, such goods are ready for final use. This implies that they need not pass through any further stage of production i.e. no further transformation is required for these goods to make them consumable. Such goods have already crossed the boundary line of production. Regards
