Gross Domestic Product (GDP) is a measure of a country's overall official economic output. It is the market value of all final goods and services officially made within the borders of a country in a year. Usually, GDP is expressed as a comparison to the previous quarter or year. For example, if the year-to-year GDP is up 3%, this is thought to mean that the economy has grown by 3% over the last year.

Gross National Product (GNP) is the total value of all final goods and services produced within a nation in a particular year, plus income earned by its citizens (including income of those located abroad), minus income of non-residents located in that country. Basically, GNP measures the value of goods and services that the country's citizens produced regardless of their location.
