Data is raw and disorganized, and can be contextualized into information. Knowledge is the determination of useful information, while wisdom is judging which knowledge is true and applying it to real life.

Data can be defined as raw facts, and information is a collection of raw data. Knowledge organizes this data but is not necessarily useful. Wisdom is the application of knowledge, thereby making it useful.
