CEVAP:

Market is an aggregate of people who, as individuals or organisations, have needs for products in a product class and who have the ability, willingness, and authority to buy such product. Despite the unbearable desire to buy a Ferrari, a young university student cannot be in the definition of Ferrari market since he/she has no economic power to buy it.

A market segment consists of a group of consumers who have similar sets of needs and wants. For car market, small sized, low cost, basic transportation automobiles may create a segment for students who are willing to buy such a car.
