When an Aboriginal is refused service in an hotel, or a woman is denied full membership of the local golf club, or a long serving employee is sacked because of age, they have been discriminated against. They have been treated less favourably than others in the same situation because they belong to a particular group or because of stereotyped ideas about people who belong to that group. If a woman is denied a promotion at work because she is a woman or because the boss believes that women are more emotional than men and do not work well under stress, for example, that would be discrimination.
