Define knowledge?

Knowledge can be defined as the state of understanding or familiarity with a subject or fact. It is the information, understanding, and skills that a person has acquired through learning and experience. Knowledge can be explicit, meaning that it is consciously held and can be easily articulated, or it can be implicit, meaning that it is unconscious and difficult to express in words. Knowledge is often seen as a key factor in understanding the world around us and making informed decisions.
