• Knowledge is a familiarity with someone or something, which can include information, facts, descriptions, and/or skills acquired through experience or education.
  • It can refer to the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); and it can be more or less formal or systematic.

    • perception
    • learning
    • communication
    • association
    • reasoning;
