What is the difference between prejudice and bias?

"Bias can be defined as an inclination of temperament or outlook, especially a personal and sometimes unreasoned judgment—i.e., prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair—for example, an overgeneralization.

Prejudice (prae=previous; judicum=judgment) can be defined as a preconceived judgment or opinion; an adverse opinion or leaning without just grounds or before sufficient knowledge; or an irrational attitude of hostility directed against an individual, group, a race, or their supposed characteristics.
