Trivia refers to bits of information, often of little importance.
The trivia (singular trivium) are three lower Artes Liberales, i.e. grammar, logic, and rhetoric. These were the topics of basic education, foundational to the quadrivia of higher education, and hence the material of basic education and an important building block for all undergraduates.
