Introversion is part of a psychological theory developed by Carl Jung that attempts to describe people by positioning them along four axes and dividing them into 16 distinct personality types. 

First, it should be noted that within Jung's theory, introversion and extroversion formed an axis, with most people belonging closer to the middle than at the extreme ends. The second issue is that this is only one of many parts of a single theory of personality which uses many factors to characterize people, not a set of simple set of distinct scientific categories such as hydrogen versus helium.

Introversion simply means that people are more inner than outer directed, often developing ideas on their own and being less focused on external rewards and social interactions than on their own goals and interests. That means that introverts are often less sociable than extroverts and prefer spending more time along. 

Introversion is not the same as shyness. Introverts are not necessarily more or less talkative than extroverts when they do socialize and thus introverts can either be quiet or loud or talkative or silent.
