Difference between gross income and income?

Income is a general term referring to one's financial gain, whether earned or unearned, received as wages, or for services, from the sale of goods or property, or as earnings on investments over a given period of time. Gross income is the total income earned from all sources (e.g. wages, property) in a given period before expenses or taxes are deducted. Net income is the income or profit remaining after taxes and expenses have been deducted.
