Feel free to guess if you don't know.
What do you understand by the term "data"?
What do you understand by the term "capta"?
What do you understand by the term "information"?
What do you understand by the term "knowledge"?
ETA: Note that "capta" is not a typo. The word intended is not "capita" or "captcha", but "capta", spelt as such.
I'm referring to the terms as used in the general field of data processing, information technolgy, information systems, knowledge bases, and similar disciplines. Also, I'm more interested in people's understanding of the terms than in their knowledge of the definitions.
