What is the difference between prejudice …

Prejudices are examples of attitudes towards a particular group. They are usually negative, and in many cases, may be based on stereotypes (the cognitive component) about the specific group while  stereotype is a cluster of ideas regarding the characteristics of a specific group.

Prejudice generally based on ethnicity, race, gender, caste and the like who mostly tend to show negative feelings towards people belonging to other groups while Stereotype described as classifying people based on their membership in a particular group, based on a certain preconceived belief which can be negative, positive or neutral and can be based on factors like gender, ethnicity, occupation etc.

Stereotypes consist of undesirable characteristics about the target group, and they lead to negative attitudes or prejudices towards members of specific groups. The cognitive component of prejudice is frequently accompanied by dislike or hatred, the affective component while Prejudice may also get translated into discrimination, the behavioural component, whereby people behave in a less positive way towards a particular target group compared to another group which they favour.

Prejudice is not based on a truth and usually originates from the lack of knowledge about a certain group of people while stereotype might be based on a truth. However, a stereotype can originate  from prejudice.
