What is the relationship among market segmentation and target marketing?

Market segmentation is the process of dividing a market into distinct subsets that behave in the same way or have similar potential for your product/service. Segmenting is done by Demographics (age, sex, income, race, etc.), geographics (international, city, state, national, climate, etc.), psychographics (personality, lifestyle, political party, etc.), behavioral characteristics (consumption status, brand loyalties, shopping habits, etc.) , and by sought after benefits that can better the lives of your segmented market with your product/service. Through this process you are able to target market to the specific segmented market fit for your product/service.
