Business is the activity of making one's living or making money by producing or buying and selling goods or services. Simply put, it is "any activity or enterprise entered into for profit. It does not mean it is a company, a corporation, partnership, or have any such formal organization, but it can range from a street peddler to General Motors." The term is also often used colloquially (but not by lawyers or public officials) to refer to a company, but this article will not deal with that sense of the word.
Business administration is management of a business. It includes all aspects of overseeing and supervising business operations and related field which include Accounting, Finance and Marketing.
Finance is a field that deals with the study of investments. It includes the dynamics of assets and liabilities over time under conditions of different degrees of uncertainties and risks. Finance can also be defined as the science of money management. Market participants aim to price assets based on their risk level, fundamental value, and their expected rate of return. Finance can be broken into three sub-categories: public finance, corporate finance and personal finance.
The majority of students studying for the master's degree in business are enrolled in makeshift programs which are generally unsatisfactory... Business administration gets a much larger portion of poor students and a smaller percentage of the best students than do the traditional professional fields.
